Elliana Morris had owned the house for six days when the cold started eating her food. She stood at the bottom of the cellar stairs in her father's old wool coat, holding a candle to a jar of pickled beets. Frost webbed the glass. The jar had been fine yesterday. Half her savings sat on these shelves in cans and jars, the buffer that was supposed to carry her through winter while she fixed the roof upstairs. A draft moved past her ankle. She followed it three steps and lost it. The cellar was long and low, stone walls sweating in patches, and the cold came from somewhere she couldn't see. She had been hunting the leak for two nights. Every crack she sealed with rag and wax pushed the chill somewhere else, like squeezing a balloon. She set the candle on the supply shelf and watched the flame. It leaned left, toward the back wall. She walked the wall with her palm out. Behind a stack of crates, the stone went cold enough to sting. She dragged the crates aside. Cans rolled and clattered on the floor. The wall behind the crates wasn't a wall. Cobwebs hung in a curtain across an arched opening, thick as gauze. Someone had bricked it up once and someone else had knocked the bricks back out. The rubble sat in a neat pile to the side, as if whoever cleared it had meant to come back. Elliana pulled the webs down with the broom. A stone archway stood behind them, older than the house by the look of the masonry. The dark inside it wasn't flat. A faint glow sat somewhere deep in the passage, low and steady, the color of a banked coal. The draft poured out of the opening in a slow, cold river. She stepped back. Her breath came out white. The air from the archway smelled like wet stone and, under that, something warmer she couldn't name. Not smoke. Not rot. Something alive. The realtor had said Moonveil House was built in 1889 by a widow who left no children. He had not mentioned a tunnel. Elliana crouched and held her hand near the threshold. The draft was steady. Constant. Whatever was on the other end was open to the air, and it was warm enough that the difference had been ruining her food for a week. She couldn't seal it. Sealing it meant living above a hole she didn't understand. She looked at the ruined jars, then at the glow. “All right” she said as she went back upstairs to grab a lantern.

Elliana came back down the cellar stairs with the lantern her father had used for storm nights. The frame was rusted at the corners. The glass was cloudy with old soot. She shook it and heard oil slosh, then struck a match and lit the wick. The flame caught weak and yellow. She turned the knob higher. It did not get brighter. She stepped through the archway. Cobwebs dragged across her hair. The passage sloped down. The stone walls were cut, not natural. Her lantern lit maybe six feet ahead and then the dark closed again like water. She counted her steps out of habit. At twenty she looked back. The cellar opening was already a pale square the size of a coin. She stopped. If the flame went out she would not find the wall by touch alone. She thought about turning around. Then she saw the writing. Someone had scratched it into the stone at shoulder height, just past the entrance, where she had missed it going in. The letters were deep and old. TURN BACK. Under that, in the same hand, smaller: THE DEAD KEEP THE DOOR. Elliana held the lantern close. Her hand shook and the light shook with it. She read the words twice. She thought of the neat pile of bricks in her cellar. Someone had left this warning. Someone else had ignored it and opened the wall anyway. Ahead, deep in the tunnel, the faint glow she had seen from the cellar was still there. Steady. Warm-colored. Closer now than it had any right to be. She could go back up, brick the arch herself, and sleep above a sealed hole for the rest of her life. Or she could see what was burning down there. She walked toward the glow. She kept one hand on the wall so she would not lose the line. The lantern coughed once and held. The passage curved. The glow grew. It was not firelight. It was steadier than fire, the color of a low sunset held still. The tunnel opened. Elliana stopped at the edge of a wider chamber. The glow came from somewhere beyond it, past a second archway cut into the far wall. Two figures stood on either side of that archway. She lifted the lantern. They were skeletons. Armored. Tall helms with narrow slits. Spears held upright in bone hands, the tips level with each other. Their jaws hung open in fixed grins. One had a spark of orange light where an eye should have been. Then the other. Elliana did not move. She did not breathe. The lantern rattled in her grip and she clamped her other hand around it to make it stop. Neither skeleton turned its head. Neither lowered its spear. They only watched her, and waited.

Elliana held still at the edge of the chamber. The two skeletons watched her with steady orange pinpricks in their skulls. She could not read them. Their spears had not moved. Their heads had not turned. She did not know if lifting her foot would end her. She tried a word. "I'm not here to steal anything." Her voice sounded thin in the stone. Neither skeleton answered. The one on the left tilted its helm a fraction. The spear tip did not drop. She took a slow step forward. The lantern shook. Neither guard moved to stop her. She took another. The left skeleton lowered its spear across its body, not at her, and turned toward the second archway. The right skeleton did the same on its side. They fell in beside her, one at each shoulder, boots of bone clicking on the stone. She understood then. They were not blocking her. They were taking her somewhere. The second archway opened into a larger hall. The glow she had followed since the cellar came from this room. It was not fire. It was the light coming off a mound of gold at the far end. Coins spilled across the floor in a slow tide. Rings and chains and cut stones caught her lantern and threw it back a hundred times. Rising out of the pile was a chair built from bones, tall and pale, the arms ending in curled finger joints. A figure sat on it. Small, robed in dark cloth stitched with faded gold. A crown of black iron and blue stones sat on a bare skull. He watched her come with eyes that held the same orange light as the guards, but quieter. The skeletons stopped ten paces from the throne and stepped back. Elliana stood alone in the coins. "Put the lantern down," the figure said. His voice was dry and level. "You won't need it here." She set it at her feet. The flame kept burning. She straightened. "You are under your own house," he said. "This is Desdemona. I am Silas. I keep the door you came through." "The dead keep the door," she said. "I saw the writing." "I wrote it." She swallowed. "Why let me pass, then." "My guards asked me. You didn't run." He tilted his skull. "Most run." "What is this place." "Not for the short answer." He leaned forward, hands on the bone arms of the chair. "You came from the house above. Who told you the tunnel was there." "No one." He was quiet a moment. The orange in his eyes dimmed and brightened. "Then we have a problem," he said. "The door only opens for someone it was waiting for. I did not send for you." He stood. The coins shifted under his feet. "Sit," he said, and pointed to the floor at the base of the throne. "I need to know how you found me before I decide what to do with you."

Elliana sat on the coins where Silas had pointed. The metal was cold through her clothes. He stayed on his feet in front of the throne of bones, hands folded, waiting for her answer. She tried to think of one that would keep her alive. "I moved into the house six weeks ago," she said. "The cellar went cold. I found the archway behind the crates. I came down because I wanted to know what was under my own floor." "Who owned the house before you." "I don't know. The sale went through a bank." Silas tilted his skull. The orange in his eye sockets narrowed. "Someone unsealed that door from your side. Not you." "I know. The bricks were stacked in a pile. Whoever did it meant to come back." He was quiet. Somewhere behind her, past the guards at the archway, a sound started. A dry scrape, like a chair pulled across stone. Then a wail, thin and climbing. Elliana turned her head. A shape came fast out of the dark between the columns. It was not a skeleton. It had no bones at all. It was a smear of grey air with a face pulled long, and it came straight at her across the coins, arms out. She threw herself sideways. The thing's fingers passed through her shoulder and the cold went into her chest like a swallowed nail. She hit the gold and rolled. It turned in the air to come back. Silas moved. He lifted a gold staff she had not seen him holding, crowned with a blue stone, and struck the butt of it once against the stone floor. The sound was small. The result was not. Blue flame burst around the grey shape, wrapped it, and ate it in one breath. The wail cut off. Ash drifted down onto the coins and went out. The two skeleton guards were already at the archway. A third figure struggled between them, another grey shape, this one bound in a loop of pale light one of the guards had cast around it. They dragged it back into the dark corridor without a word from Silas. Their boots clicked and faded. Elliana stayed on her hands and knees. Her shoulder still burned cold. Silas lowered the staff. He looked at the place where the soul had been, then at her. For the first time his voice was not level. "That should not have happened," he said. "Nothing in this hall moves without my say." "It came for me." "I saw." He was quiet a long moment. "I don't know why." He stepped down off the pile of coins and stopped an arm's length from her. The crown caught the lantern light. "Stand up," he said. "The interrogation is finished. We have a worse question now. Something in my hall wants you dead, and it did not ask me first."

Elliana got to her feet. Silas had gone back up the coin pile to speak with the guards who had dragged the second grey shape into the corridor. He waved her toward the archway she had come through. "Wait there," he said. "Don't cross it. Don't touch it. I need a moment." She walked back across the hall. Her shoulder still ached from where the spirit had pushed cold through it. The archway rose ahead of her, stone laced with old cobweb, a faint glow bleeding out of the dark inside. One skeletal sentry stood beside it. The other must have gone with the guards down the corridor. The one that remained was wrong. It had been still as furniture on the way in. Now its helmed skull turned in small jerks, tracking her, then the arch, then her again. Its spear tip drifted off the vertical. The orange in its eye sockets pulsed, dimmed, flared. Elliana stopped six paces short. "I'm just going to stand here," she said. Her voice came out steadier than she felt. "He told me to wait." The sentry took one step sideways and planted its spear across the opening. Her stomach dropped. That arch was her only way back to her cellar. To her house. She thought of the warning carved in the tunnel wall: the dead keep the door. She had assumed that meant Silas. "You know me," she tried. "You walked me in." The skull cocked. The orange guttered like a candle in wind. Then the spear came off the arch and swung level at her chest. Elliana stepped back. "Silas." The sentry lunged. She threw herself down. The spear point scraped the stone where her ribs had been. She scrambled sideways along the wall, hands raw on grit, cornered against cold rock. The skeleton pivoted with that same jerking wrongness and brought the spear up for a second strike. A blue streak came through the archway. A fox, small and pale, wrapped in cold blue flame, shot past her legs and slammed into the sentry's knee. Bone cracked. The spear went wide. The fox turned in the air, and where it landed it was not a fox anymore. Silas stood in its place, robed, crowned, gold staff already in his hand. The blue stone at its head burned white. He struck the floor once. Blue fire climbed the sentry from boots to helm and held it there, shaking. The orange in its sockets snuffed out. The armor dropped in a clatter. Silas stepped over the bones and took Elliana's elbow. His grip was cool and exact. "Something is happening to my souls," he said. "You are not going back through that door tonight." "My house — " "Will still be there. You won't, if you cross now." He guided her away from the arch, into the hall. "You'll stay in the palace until I know what is hunting you. That is not a request." Elliana looked back once. The archway glowed, empty, quiet, closed to her.
