Sam Marlowe kept a photograph of the stolen relic pinned above his desk, and every crime boss in the city wanted him dead for chasing it. He'd taken the job three days ago. Now a purple ogre in a black pinstriped suit stood on the sidewalk outside, cracking his knuckles. Sam watched through the blinds. The ogre wore two-tone shoes and a tie loud enough to hear across the street. A big pistol bulged under his jacket. Knuckles Malone. Every hood in town knew the name. He'd trailed Sam from the docks, and now he waited by the only door out. Sam's office had one exit and no back stairs. If he stepped through the door, Knuckles would fold him like a road map. Sam poured a drink he didn't touch. He needed the ogre gone, or he needed him confused. With a brain that size, confusion was easier. Sam found a spare fedora on the coat rack. He set it on his desk lamp and angled the shade to throw a man's shadow on the blinds. From the street it would look like Sam, sitting, working late. Then he grabbed his phone. He dialed the number on a matchbook from a rival boss's club. He kept his voice low and hurried. "Tell your boss the detective's got the relic in his office. Right now. Send men." He hung up before they could ask questions. Then he waited by the window. Ten minutes crawled. A long black car rolled up and stopped hard. Three more hoods climbed out, purple and huge, hands inside their coats. They saw Knuckles. Knuckles saw them. "You're on the wrong corner," one called. "This corner's mine," Knuckles said. His voice came slow, like gravel in a bucket. The first hood shoved him. Knuckles swung. The punch lifted the smaller ogre off his feet and dropped him in the gutter. The other two piled on. Fists cracked against jaws. A gun went off into the sky. Somewhere a woman screamed and glass broke. Sam slipped out the side while all four ogres tore at each other. He kept to the shadow of the building and walked fast, not running, hat low. Behind him a body went through a shop window. He made it two blocks before he let out his breath. He'd bought himself the night. But he'd also told a crime boss the relic sat in his office. By morning, that boss would send men to search it. They'd find nothing, and they'd know Sam had played them. Sam stopped under a dead streetlamp. He couldn't go back to the office now. Not tonight, maybe not ever. And the only lead he had on the real relic was a name he'd overheard at the docks, a name he still couldn't place. He turned up his collar and started walking toward the water.

The docks stank of fish and diesel. Sam had a name he'd overheard here three days ago, nothing more. He walked the piers and listened. Dockhands shrugged when he asked. A fog rolled in off the water and swallowed the streetlamps. He was chasing a shadow, and the night was slipping away. Then he saw the shop. A window full of little ships and painted harbors. Inside sat a model of a rusted German submarine on a tiny dock, its shoreline fading into cotton mist. A brass plate read Fogbound Harbor. Sam remembered the name now. Not a man. A place. A slip down at the far end. He found the slip. A boat rocked against the pilings. On the deck stood a shark-faced man in a pea coat and rubber waders. A hook curved where his right hand should be. He gutted a fish with the hook and flicked the guts into the water. This was Captain Finn Blackwater. The name from the docks. "You're the detective," Blackwater said. His teeth were rows of white needles. "Word travels. Every hood in the city's been down here sniffing." Sam kept his hands loose. "I'm looking for the relic." Blackwater laughed, wet and sharp. "So is everyone. It's cursed, that thing. Bosses killing bosses over it." He drove the hook into the deck rail and left it there. "I had it. I want it gone. Give me a reason it should be you." "I'm the only one not trying to shoot you for it," Sam said. The captain studied him a long moment. Then his black eyes flicked past Sam's shoulder. His grin fell. Sam turned. A huge purple shape came down the pier. Black pinstriped suit, loud tie, two-tone shoes catching the dock lights. Knuckles Malone. Fresh cuts crossed his face from the street fight. He'd survived it, and he'd tracked Sam here. "Detective," Knuckles said. His voice ground like gravel. "You cost me a bad night." He drew the big pistol from under his coat. Blackwater moved fast. He kicked a rope free, and the boat drifted from the pilings. "Not on my dock," he growled. He yanked the hook from the rail. Sam dropped behind a stack of crates. Knuckles fired. The shot splintered wood by Sam's ear. The ogre lunged onto the boat, and it tipped hard under his weight. Blackwater swung the hook and caught Knuckles across the arm. The pistol splashed into the black water. The two crashed together on the pitching deck. Sam saw his chance. He grabbed the mooring line and hauled the boat tight to the pier. "The relic," Sam shouted. "Where?" Blackwater, pinned under the ogre's fist, spat blood. "Hidden. Cannery. North end. Take it and go!" Knuckles roared and drove Blackwater down. Sam let go of the line. The boat swung out into the fog, both men still fighting. Sam ran. He had his lead now. But Knuckles knew where it pointed, and one of them would reach the cannery first.

Sam ran until the fog thinned. He had the cannery's location now, but Knuckles Malone had heard it too. The ogre had survived Blackwater's hook. He was hunting Sam through the dark streets, and one wrong turn meant a bullet. Sam needed the enforcer gone before he could reach the relic. He couldn't outrun him. So he decided to outthink him. He made for the one place Knuckles wouldn't follow. Eight stories of brown stone rose ahead, cell windows barred, a helipad crowning the roof. The police station. A hood with a gun didn't walk through those doors. Sam did. He climbed the steps and asked for the only cop who might listen. Lieutenant McSnork worked Homicide. Sam had crossed him before. The Ork was squat and grey-green, with small horns and a cigar clamped in pointed teeth. He looked up from his desk and frowned. He didn't like Sam. He liked liars less. "Marlowe." Smoke rolled from the cigar. "You look chased." "Knuckles Malone," Sam said. "He opened fire on me at the docks tonight. He's outside now, waiting for me to leave." McSnork stood. His yellow eyes narrowed. "Malone. Crime boss muscle." He chewed the cigar. "You bring shooting to my streets?" "He brought it. I brought it here, to you." The Ork studied him a long moment. He didn't trust Sam. But a gun going off near citizens was a line he wouldn't let a hood cross. He grabbed his coat. "Show me." They stepped out under the station lights. Knuckles waited across the street, purple face bruised, one hand under his coat. He saw the badge on McSnork's chest and froze. "Malone," McSnork called. "Hands where I see them." Knuckles hesitated. His hand twitched toward the holster. That was the mistake. McSnork drew first, fast for a squat thing, and three uniformed cops spilled out behind him. Guns leveled from every side. The ogre weighed it. One cop he might beat. Not four, not under the station's own lights. Slowly he raised both hands. "Discharging a firearm at the docks," McSnork said. He snapped cuffs around the thick wrists. "You'll sit in a cell while I check the story." They walked Knuckles up the steps and through the doors. At the threshold the ogre turned his bruised face back to Sam. He said nothing. He didn't need to. His look promised he'd remember. McSnork stopped beside Sam. He didn't smile. "Malone's off the street. For now." He bit down on the cigar. "But you lied to me once, Marlowe. I don't forget that either." He turned and followed his men inside. Sam stood alone on the steps. The hunter was in a cage. The path to the cannery was open. But Knuckles wouldn't stay caged long, and a lieutenant who half-trusted him now watched his every move. Sam pulled his coat tight and headed north.

Sam reached the cannery before dawn. It sat locked and dark. A guard slouched by the loading door, rifle across his knees. Two more walked the fence. Sam crouched behind a stack of crates and watched. He had the location. He couldn't get inside. Every minute he waited, the relic slipped further out of reach. He pulled out the phone in the alley booth and dialed the one man who solved locks and papers. Lysander answered on the second ring, calm as ever. "You found your cannery," Lysander said. "And now you can't open it." "Guards on every side," Sam said. "I need a way past them." "Then don't go past them. Go through the one door they don't watch." A pause. "Sit tight. I'm sending someone who can walk in the front." Sam didn't like the sound of that. He liked it less when she arrived. She came from the shadows on high heels, and the guards stopped breathing. Red hair fell over the horns. Wings folded tight against her back. Sam knew her by reputation. Scarlett Inferna. Mister Big's girl. The kind of woman a smart man crossed the street to avoid. She stopped beside Sam's crates without looking at him. "The elf sent me. He owes me now, not you." "Why help me at all?" Sam asked. "Mister Big wants the relic." She checked her nails. "I want him wanting less." She stepped into the light. The guard at the door stood fast, rifle forgotten. She said something Sam couldn't hear. The man's face went slack. He unhooked a ring of keys and handed them over. Then he walked off toward the fence like a sleepwalker, taking the other guards with him. Whatever she'd promised them, it led away from the door. "Two minutes," Scarlett said. "That's all they hold." Sam ran for the door and worked the keys. The third one turned. The lock gave. He shoved the heavy door inward and slipped through into the dark cannery. Inside, machines sat still under grey dust. Sam moved down a row of rusted vats. He found a back office, its window painted black. On the desk sat a small wooden model of a harbor, boats and piers carved fine. He knew at once it was no toy. This was the thing the bosses were killing over. He reached for it. The office phone rang. Loud. Once, twice. Sam froze. Someone knew the relic lived here. Someone was checking the line. He grabbed the model and turned. Through the black window, headlights swept the yard. Car doors slammed. Not police. Scarlett was already gone. The guards she'd led away were shouting now, awake again, pointing at the open door. Sam had the relic in his hands. He also had a building full of Mister Big's men between him and the street. The lock was open. So was the trap.

Sam clutched the wooden harbor model and ran for the loading door. Headlights filled the yard. He could not walk out the front with the relic in his hands. Every hood in the city knew what it was. Carrying it in the open would paint a target on his back. He needed a place to hide it, fast. He ducked behind a rusted vat and pressed the model against his chest, thinking. The office door burst open. Knuckles Malone filled the frame, his purple bulk blotting the light. The ogre held a pistol the size of a wrench. His loud tie hung crooked over his black pinstripes. "Marlowe," he growled. "You got somethin' that ain't yours." He'd hunted Sam across the city, and now he'd cornered him at last. Sam did not run. He set the wooden model on the floor, in plain sight, and stepped back with his hands raised. "Take it," he said. "It's yours. Tell your boss you found it." Knuckles blinked. His slow brain chewed the offer. He shoved the pistol into his holster and reached for the prize. "Smart human," he grunted. The moment the ogre's fingers closed on the model, a small grey shape stepped from the dark behind him. Mister Big. The goblin came no higher than Knuckles' belt, but the men in the doorway froze at the sight of him. Gold chain. Yellow eyes. A smile full of teeth. He was the boss nobody in the city dared name aloud. "Knuckles," Mister Big said softly. "That belongs to me." Knuckles turned, still gripping the model. Confusion crossed his heavy face. Two loyalties pulled at him at once, and his hands did not know which to obey. "Boss said bring it to him," the ogre mumbled. "Not you." "Wrong boss." Mister Big snapped his fingers. His men raised their guns. Sam slid sideways along the vats while the two crews stared each other down. Scarlett had wanted her Mister Big wanting less. Instead Sam had handed the relic straight into a fight between him and the rival crew. He reached the loading door and slipped into the cold yard. Behind him the shouting started. Then the shooting. He did not stop until the cannery was two blocks gone. He pressed his back to a wall and breathed. His hands were empty. The relic was lost. But he was alive, and the two crews were now killing each other over a wooden toy instead of hunting him. A phone booth glowed on the corner. Sam dialed. Lysander answered on the second ring. "You're breathing," the elf said. "You didn't keep the relic." "They've got it," Sam said. "Both of them. They're tearing each other apart to hold it." "Then you know where it will be," Lysander said. "With whoever's left standing." Sam watched smoke rise over the rooftops. Whoever won that fight would own the relic next. And he meant to be there when they did.

The shooting stopped an hour before dawn. Sam waited in a doorway and watched the cannery. When the smoke thinned, one truck rolled out. Knuckles Malone sat behind the wheel, alone, the wooden harbor model on the seat beside him. Mister Big's crew had lost. Malone had won, and he still blamed Sam for the double-cross that started it all. As long as the ogre walked free, Sam couldn't show his face on the street. Every corner held a gun with his name on it. Sam had one card left. He crossed town to the police station and found Lieutenant McSnork at his desk, cigar clamped in his teeth. The squat Ork looked up with yellow eyes and did not smile. McSnork had helped Sam once before, and he'd regretted it. He trusted Sam about as far as he could throw the building. "You again," McSnork said. "Last time cost me paperwork." "Knuckles Malone is driving a truck across the city right now," Sam said. "He's got a gun and a grudge. He shot up the docks and just shot up a cannery. Bodies in there, Lieutenant. Yours to count." McSnork chewed the cigar. "And you know this how?" "I watched it," Sam said. "Pick him up and you close two shootings tonight. Leave him loose and he kills someone by morning." The Ork studied him a long moment. He didn't like Sam. But he liked killers on his streets even less. He stood, grabbed his fedora, and barked orders at two officers. "Get the truck. Alive if you can." Sam rode along and pointed the way. They caught Malone at a stalled light. The ogre saw the badges and reached for his holster, but three barrels through the window changed his mind. Cuffs wouldn't fit his wrists, so they used chain. The wooden model sat on the seat where he'd left it. McSnork bagged it as evidence and never asked what it was. "He's off the street," McSnork told Sam. "For a while. Don't make me sorry." Sam found a phone and called his office. Dolly answered on the first ring. Her voice was flat, the way it got when she'd been scared and wouldn't say so. "You're alive," Dolly said. "I hoped. I didn't count on it." "Malone's in a cell," Sam said. "I can walk again." "Good. Lysander called twice." A pause. "The relic's in a police evidence bag now, Sam. You handed it to the one place you can't just walk into and take it." Sam looked back at the station. McSnork carried the wooden model inside under his arm. The ogre was caged. The street was safe. But the relic he'd chased across the city now sat locked in a building run by a cop who didn't trust him, guarded by law instead of guns. "I'll figure it out," Sam said. "You always say that," Dolly said, and hung up.

The relic sat in an evidence locker eight floors up. Sam stood across from the brown stone police station and knew he couldn't just walk in and take it. McSnork had bagged the wooden model himself. The Ork trusted Sam about as far as he could spit, and Sam had nothing to trade. He needed leverage. So he called the one man who dug through papers instead of faces. Lysander met him in a diner two blocks from the station. Sam's partner wore a navy suit that cost more than a cop's yearly pay, and he ordered nothing. He worked cases for sport, funded by family money, and he liked a puzzle the police wouldn't touch. "You want the model back," Lysander said. "McSnork won't give it. So you need something he wants more." "I've got nothing," Sam said. "You have me." Lysander slid a folder across the table. "Three bodies in the warehouse district. Same six weeks. The police called it coincidence and closed the file. I don't believe in coincidence." Sam opened the folder. Names, dates, a map. "How's this help me with McSnork?" "It doesn't. This does." Lysander laid down a second page. A city waste contract, signed and stamped. "Paid to a company that doesn't exist. Harbor district. Someone in the mayor's office is stealing." Sam saw it then. A dishonest cop wanted a bribe. An honest one wanted a bigger fish. He found McSnork at his desk, cigar down to a stub. The Ork didn't look up. "You again. I told you not to make me sorry." Sam dropped the contract on the blotter. McSnork read it. His yellow eyes went flat and hard. "Where'd you get this?" "A friend who reads papers," Sam said. "Someone's robbing the harbor district blind. Same district where your shopkeepers won't meet your eyes. You've been hunting the thread. I'm handing it to you." McSnork chewed the dead cigar. He knew the mayor kept things quiet. He'd been looking for the line he wouldn't cross, and now it lay on his desk. "What's the price," he said. Not a question. "The wooden harbor model in your evidence room. It's not tied to any murder. Sign it out to me." A voice cut in from the doorway. "That contract is mine to untangle." Aldric Quillscale stood there, the mayor's chief administrator, silver scales catching the light, feathered crest stiff. He'd traced the phantom company himself and meant to fix it before the mayor heard. He hadn't counted on a detective finding it first. "Give me the papers," Aldric said, "and the model is yours. Both of you stay quiet." McSnork looked at Sam. Sam looked at the raptor. A trade, three ways. They made it. An hour later Sam walked out of the brown stone station with the wooden model under his arm. Then a clerk called after him. Someone had already posted bail for Knuckles Malone.

Sam walked out of the police station with the wooden harbor model under his arm. He had it at last. But the clerk's words still rang in his ears. Someone had posted bail for Knuckles Malone. The ogre was loose again, and he wanted Sam dead. Sam couldn't go home. His office was ash. Every hideout he knew, the mob knew too. He needed a spot no one would think to check, and he needed it in the next hour. He found a payphone and dialed Lysander. "You have the model," his partner said. Not a question. "And nowhere to sit with it. Malone's out. He'll hit every rat hole in the city." "Then don't pick a rat hole." A pause. "Go where he already burned. He won't watch a corpse twice." Sam looked at the wooden model. Lysander was right. Malone had already torched Sam's office. He'd crossed it off his list. Nobody guards a dead building. Sam took the long way to the four-story brownstone. The neon sign still buzzed near the roof, throwing orange light on the scorched stone. The lower floors were black with smoke. The front door hung on one hinge. Sam slipped inside and climbed through the wreck of his own life. Dolly Valentine was already there. She sat on an unburned crate near the window, a flashlight in her lap, his old case files stacked at her feet. His secretary. The one person who'd kept looking when he vanished. She stood when she saw him, and her jaw tightened. "You're alive," she said. "I wasn't sure." "Dolly. You shouldn't be here." "Neither should you. It smells like a fire." She looked at the model under his arm. "That's the thing everyone's killing over." "It is." She didn't reach for it. She reached for a chair instead, dragged it up, and set it steady. "Then sit before you fall down. You look terrible." Sam sat. For the first time in days, no one was hunting him at that exact moment. He set the model on the crate. It was just carved wood, a little harbor with tiny ships. Hard to believe men had died for it. Dolly clicked off her flashlight. "I saved what I could from the files. Your notes. The docks stuff." She said it flat, the way she said everything. "Figured you'd need them." Sam started to thank her. Then he saw her face change. She was looking past him, at the window. Outside, the orange glow of the sign lit up a figure on the street below. Tall. Robed in white. Three eyes turned up toward the burned office. The Mayor stood there, still as a photograph, staring straight at the window where Sam sat with the relic. Dolly's voice dropped. "Sam. Who is that?" Sam didn't answer. He'd hidden from every crook in the city. He had never once thought to hide from the man who built it.

Sam didn't move. The three-eyed figure below stayed still. Then it raised one white hand, six fingers spread, and pointed at the door. An invitation, or a command. Sam picked up the wooden model. He looked at Dolly. "Stay up here," he said. "No." She stood. "You've run from everyone in this city. You're not running from this alone." She took the flashlight and went down the stairs ahead of him. They met the Mayor on the burned ground floor. Up close he was taller than the doorframe. His white suit caught the neon glow from above. Both mouths were shut. All three eyes fixed on the model under Sam's arm. "You made this city," Sam said. "So the drunk was right. The old bones do shake loose." "I did not come for the carving," the Mayor said. "Someone left the walls. That has never happened. You touched every corner of my city chasing that wood. You saw the seams. Tell me where a person could slip out." Sam's mouth went dry. He thought of the cannery, the harbor, the fog. Places that felt too thin, too made. He hadn't known why. Now he did. A new figure stepped in from the street behind the Mayor. Silver scales, a feathered crest, a black cutaway coat. Aldric Quillscale, the administrator who had bound Sam, McSnork, and the mayor's office to silence over the harbor graft. He moved fast for a man his size. "Sir," Quillscale said. "You should not be out here." "He knows the harbor," the Mayor said, not turning. Quillscale's yellow eye flicked to Sam, then to the model, then back. Sam read the flick. The administrator was afraid. Not of Sam. Of what Sam might say in front of his master. "The harbor district is my file," Quillscale said. "I will handle the gap." Sam saw the play. Quillscale wanted him quiet. The fake waste contracts. The dead men no one solved. All of it sat in the same harbor where the walls had worn thin. Whatever left the city had left through the rot Quillscale was hiding. Sam could stay silent and keep his deal. Or he could trade the one thing he had left. He held out the wooden model. "You want the seam," he told the Mayor. "It's in the harbor. Same place your administrator's been burying bodies and paying a company that isn't real. The wall's thin there because nobody minded it. Take the carving. It came from that ground. It'll lead you straight to the hole." The Mayor took the model in six-fingered hands. Both mouths opened, then closed. "Then I will look at the harbor," the Mayor said. He turned and walked into the street. Quillscale stared at Sam. "You just broke our silence." "I know," Sam said. The relic was gone. And now the man who built the world was walking toward the one secret that could bury them all.

Sam followed the Mayor to the harbor. Dolly came too, walking fast to keep up. Quillscale trailed behind them, silent, his scaled hands twitching. The fog thickened as they reached the water. Sam had chased the wooden model to this same shore. Now the man who built the city carried it toward the edge of everything. The harbor lay still and wrong. Boats rocked but never drifted. A gray U-boat sat grounded on the bank, out of place and rusting. Far off in the mist, long-necked shapes rose and dipped, calling to each other. Sam had felt this spot was thin before. Now he understood. The wall here had worn through, and something on the other side was pressing back. The Mayor stopped at the water's edge. He raised the wooden model in six-fingered hands. "The seam is here," he said. "I will close it and burn the carving." Sam saw a shape in the fog. Not a boat. A man in a captain's cap, waders, a hook where one hand should be. Captain Finn Blackwater. The shark-faced sailor who had first sent Sam after the relic, then cut a boat loose to save his life. Blackwater waved his hook and shouted across the water. "You can't open it!" Blackwater called. "That's how the thing gets through. The wall keeps it out, not in!" Sam's stomach dropped. The Mayor had it backward. Something wanted out of the other side, into the city. Quillscale had buried bodies here for years. The rot had thinned the wall from within, and now a door hung ready to swing wide. "Don't touch it," Sam said. "You open that seam, you let it in." The Mayor turned all three eyes on him. "I made this wall. Nothing comes through it." "You made it," Sam said. "Then he rotted it." He pointed at Quillscale. "Ask him what's under the dock." Quillscale said nothing. His yellow eyes fixed on the model. The Mayor looked at his administrator for a long moment. Then he set the wooden model on the ground, whole, and did not break it. "The wall stays shut," the Mayor said. He walked into the fog. The long-necked shapes sank below the water. The harbor went quiet. Sam let out a breath. He had stopped the breach. But the model still sat on the wet stones, uncracked, undestroyed. The Mayor had left without burning it. Dolly picked it up. She held it out to Sam. "He didn't take it," she said. Sam stared at the carved wood in her hands. The relic was still real. Still the key to the thinnest wall in the city. And every crime boss who wanted it was still alive, still hunting. Blackwater's boat had already slipped back into the mist. "We're not done," Sam said. He took the model. It felt heavier than before.

The fog still hung over the water when Sam turned the wooden model in his hands. The Mayor was gone. Blackwater's boat had slipped away. Dolly stood close, watching the carved boats and the little grounded U-boat, all frozen in the wood. Sam knew what the relic could do now. He didn't know why it worked, or who he could hand it to without dooming the city. Every boss still wanted it. He needed answers before someone took it by force. "Somebody knows what this is," Sam said. "Better than me." A voice answered from the mist. "I do." A thin man stepped out along the bank. Ginger curls stuck out under a cap with a feather. He wore a tweed coat with patched sleeves and a grin like he'd won a bet nobody else knew about. Sam had never met him, but he'd felt eyes on his back for days. The stranger held a small notebook, one finger keeping a page. "You've been following me," Sam said. "For a week." The Watcher didn't blink. "You carry the seam in your hands." Dolly moved between Sam and the stranger. "Say what you mean." "The carving isn't a map," the Watcher said. "It's a lock." He nodded at the harbor, at the still boats and the shapes sunk under the water. "Every boat, every wreck, carved where it sits. Match the model to the real harbor, the wall opens. Break the model, the wall opens for good." Sam's mouth went dry. "The Mayor almost burned it." "Then he almost let the thing out." The Watcher flipped his notebook shut. "The bosses think it buys power. They're wrong. It buys a door. Whoever cracks it drowns the city." Sam looked at the wood. He'd chased it thinking it was worth killing for. It was worth more, and worse. He couldn't hand it to a boss. He couldn't give it to the cops. He couldn't destroy it. He couldn't even keep it, not with Malone hunting him. "Who taught you this?" Sam asked. "Someone who told me to look away at the end." The grin held. "I never do." "Then help me hide it," Sam said. The Watcher shook his head. "I track things. I don't carry them." He tucked the notebook into his coat and stepped back into the fog. "But I'll warn you. The one nobody names already knows you have it. He doesn't want power. He wants the door." He was gone before Sam could ask more. Dolly touched Sam's arm. "You know what it is now." "Yeah." Sam wrapped the model in his coat, hiding the carved boats. His hands weren't steady. "It's a lock. And I've got it, and there's a boss out there who wants to open it. Not to win the city. To sink it." The question of what the relic did was answered. A worse one had taken its place. Sam started walking, the door to the city held against his chest.

Sam carried the wooden model back to his burned-out office, the carved boats pressed to his chest. Dolly waited in the doorway. Lysander stood by the window, sorting salvaged files by lamplight. Sam set the model on the desk. "A boss out there wants to open this. I don't know his name. I can't hit a man I can't see. If I sit here, he takes me from behind." Lysander tapped a file. "Then name him. Bosses leave tracks. Contracts, bribes, bodies. This one leaves none." He slid a page across the desk. "No name. No face. Nobody in the district will speak of him. That silence is the track." Dolly leaned over the page. "A man everyone's scared to name. The Watcher said the same thing. The one nobody names already knows." Sam looked at the model. He thought of the Mayor, who had come to his window and spared this lock. "There's one person who'd know a rival that quiet," Sam said. "The man who built the walls." The lamp guttered. The room went cold. A tall figure filled the doorway, dressed all in white, three eyes above two stacked mouths. The Mayor stepped inside without a sound. Dolly backed against the wall. Lysander set down his file and said nothing. "You still have it," the Mayor said. His eyes moved to the model. "Good." "Somebody wants to open it," Sam said. "Drown the city. I need his name." The Mayor was quiet a long moment. "He is the other half of me," the Mayor said. "I built the city. He wants it gone. We were one thing once. Now we move apart." "He got a name?" "He answers to the Boss." The Mayor's voice went flat. "He worships what the wall traps. He would open the door to reach it. He has felt the city shake. He has seen a hand bleed through." Behind the Mayor, the shadows in the stairwell thickened. A second figure stood there, the Mayor's mirror. Black hair, three burning red eyes, black coat. The Boss had followed the Mayor up. He had heard everything. "You," Sam said. His hand found nothing but the model. "Me," the Boss said. His eyes fixed on the carved boats. "You have my door." The Mayor turned to face his mirror. Neither moved toward the other. The two burning shapes stood filling the stairwell, white against black, and the whole floor seemed to lean between them. "Run," the Mayor told Sam. "Take it and run." Sam grabbed the model. Dolly caught his sleeve and pulled him toward the back stairs. Lysander went ahead, sweeping the files under his coat. Behind them the Boss spoke once more, plain and final. "I know your face now, detective. I know your girl. There is nowhere in the city I cannot reach." Sam ran into the dark with the lock in his arms. He had his enemy's name. Now the Boss had his.

Sam ran until his lungs burned. He didn't stop until the harbor fog swallowed him whole. Dolly stayed at his side. Lysander pulled up beside them, coat bulging with files. The wooden model dug into Sam's ribs. The Boss knew his face now. He knew Dolly's. Running only bought minutes. The lock was the thing everyone wanted, and Sam finally understood the truth. As long as it existed, they'd hunt him forever. "We can't hide it," Sam said. "We can't sell it. Every faction wants it whole. The only way out is to break it." Lysander studied the carved boats by lamplight. "Break it wrong and you turn the key," he said. "You'd flood the city yourself." A voice answered from the dark. "He's right." The Watcher stepped out of the fog, grinning, notebook already open. Sam had met him once before, the strange man who knew things nobody should. "The lock opens the wall," the Watcher said. "But a lock can jam." "How," Sam said. The Watcher pointed past the pier. The fog thinned. Sam saw still boats that rocked but never drifted. A grounded warship rested on the bank. Far off, long necks rose through the mist and called to each other. This was the place the wall trapped. This was the other side. "The lock only works here," the Watcher said. "Bring it to the seam. Force it against the tumbler. It splits or it opens. You get one turn." He tapped his notebook. "I won't watch the moment. I never do." He walked back into the fog. Dolly caught Sam's arm. "That's a coin flip with the whole city on it." "It's the only flip we get," Sam said. "He finds us tonight either way." Lysander knelt at the water's edge. He ran his fingers along a groove in the stone where the fog bled through. "The seam's here," he said. "Two halves of a wall. One weak line." Sam pressed the wooden model into the groove. The carved boats caught, then stuck. Something clicked deep inside. The ground shook. A hand pushed against the fog from the far side, five fingers spreading, testing. "Turn it or lose it," Lysander said. Sam gripped the model and wrenched it the wrong way, against the tumbler, with everything he had. Wood screamed. The hand jerked back. The model cracked down the middle. Both halves went dead in his palms. The shaking stopped. The fog rolled back over the still boats and the warship, and the seam sealed cold. Sam knelt in the wet stone, holding two useless pieces of wood. No lock. No door. Nothing left to hunt him for. Dolly let out a breath. "It's over." "The lock is," Sam said. He looked at the broken halves. "But I jammed his door in his face. The Boss doesn't have another key." He stood. "So now he needs a new way through. And he still knows my face."

Sam stood at the door of the black house. The lock was gone. Inside, the Boss waited in the dark, and he would not walk a single step toward the white towers on his own. Sam had the Mayor's word. He had an open cell. He had no way to march a city-hating thing across town to the one meeting it would never choose. The Watcher sat on the curb nearby, notebook open on his knee. He had followed Sam since the docks, grinning like a man watching the end of a bet. Sam knew him as the one who told the truth no boss would. "He won't come," Sam said. "He'll walk into the wall before he walks to the Mayor." "Then don't lead him," the Watcher said. He did not look up from his page. "Chase him." He closed the book. "He runs from the Mayor. Make this place worse than the room. He'll run the only way left." Dolly stepped from the shadow of the house. She had refused to wait at the towers. "You want to herd him," she said. Plain, blunt. "Like cattle." She looked at the black doorway, then at Sam. "Fine. I'll be the thing he runs from on this side." "No," Sam said. "He knows your face. He threatened you." "That's why it works," she said. "He wants me. He'll chase me toward the one door I run through." She did not wait for his answer. She never had. Sam went in first. The dark inside pressed on his skin like cold water. The Boss turned. Two eyes, wrong and bright, found Sam's face. "You freed me," the Boss said. "You should run." "I came to finish it," Sam said. He tipped over a lamp. Oil spread. He struck a match and dropped it. Fire climbed the wall. The Boss hissed and backed from the flames, toward the only open door. The Boss burst out into the street. Dolly stood waiting. "Hey," she called, and ran. The Boss went after her, fast and furious, exactly as the Watcher said. Sam ran beside her. Block after block, the two of them drove the thing toward the glow at the city's center. The white towers rose ahead, pale and tall, grown from the ground like bone. Dolly reached the great white steps and spun aside. The Boss did not stop. He hit the towers' tall door and it swung wide. He stumbled through, into light. Sam came through behind him. The Mayor stood at the window, three eyes open, waiting as promised. The Boss saw his other half and froze. "No," the Boss said. "Not with him." "I know you're right," the Mayor said softly, the same words he'd given Sam. He stepped forward. The Boss stepped back and hit the closed door. Trapped. Both halves in one room. The thing Sam had chased for twenty days. Sam grabbed Dolly and pulled her against the wall. The air began to hum. The two figures faced each other across the white floor, dark and light, split down a seam Sam could almost see. "This ends one of us," the Boss said. "It ends both of us," the Mayor answered. "We were one." He reached out his six-fingered hand. The Boss, hating it, reached too. Their fingers met. Light flooded the room. Sam shut his eyes and held Dolly. A sound like the whole city drawing breath rolled over them. Then silence. Then nothing but the hum of the towers settling. Sam opened his eyes. The floor was empty. Two halves gone. Where they had stood lay the small enamel figure, the two faces fused now into one face, whole, no seam. The city would not flood. No boss would open a wall that no longer had a weak point to open. The hunt was over. Dolly stood close, her hand still in his. For years she had never said a word. Sam had never said one either. He looked at her, at the dust on her white dress, at the fact that she had run toward the thing that wanted her. "You should've stayed back," he said. "You needed a face he'd chase," she said. "I had one." She did not look away. Sam thought of his brother, found in pieces, no one looking. He had gone looking for a relic and found a whole city to save. He had saved it. He picked up the fused figure and slipped it into his coat. Outside, the fog over the harbor was thinning. Sam took Dolly's hand and led her down the white steps, into a city that would wake up tomorrow and never know how close it came. That was enough. For once, finishing the job was enough.
