Captain Mark Halloway hated this fort, but he hated losing men more. Three days ago, Daniel Crewe walked past the north wall and never came back. Now Halloway stood in the snow-packed yard, watching soldiers load wooden crates onto a wagon. He had not wanted this posting. A superior officer had sent him here to open trade with the Blackfeet and keep the peace. Instead he kept writing names in a ledger of the missing. Private Tim Smith hauled a crate up onto the wagon bed and did not set it down gently. He slammed it. The horses shifted in their harness. Daniel had been his bunkmate. Their last words had been an argument about boots left by the door, and Tim had not stopped thinking about it. "You're going," Halloway said. "Daniel went north along the river. You follow it. You find him." Tim straightened. His face was too young for the cold. "I find him. Yes, sir." "Take enough food for a week. Powder, dry wood, a blanket roll." Halloway nodded at the crates. "The river bends hard past the pines. Stay on this side of it." "And if he's dead?" The question landed flat in the yard. Halloway did not answer fast. The Blackfeet had come to him with stories. A thing larger than a wolf. A thing that walked upright. He had written it in his report as folklore. He still believed that. "Then you bring back what's left," Halloway said. "And whatever took him." Tim stared at him. "Something took him. Something took him, and nobody here will say it." "Folklore doesn't take men, Private." Halloway heard how thin it sounded. Tim shouldered a pack. He loaded a short-handled axe, a rifle, and a sack of hardtack. He checked each strap twice. Then he walked to the gate and waited for it to open. The soldiers dragged the timber gate wide. Beyond it the land ran white and empty to the snow-dusted rocks along the river. Wind cut through the opening. Tim stepped into it alone. Halloway watched the private shrink against the snow. The boy moved steady, head down, following the water north. Smart. Careful. Maybe careful enough. Then Halloway saw them. On the far ridge, past the pines, figures stood against the white. Blackfeet. Four, maybe five, wrapped in hide. They did not move. They watched the private walk into the open the way men watch a deer step toward a trap. Halloway's chest tightened. He raised a hand to call Tim back. The wind swallowed his voice. Tim kept walking, smaller now, nearly to the bend where the river turned behind the trees. The watchers on the ridge turned their heads and followed the boy with their eyes. Then they looked across the valley, straight at Halloway. One of them lifted an arm and pointed north, past the private, toward something Halloway could not see. He shut the gate himself. He had sent the boy out. Now he had to decide whether to go after him.

Halloway rode out at dawn. He had sent one man north with a week of food and a blanket. Now he knew the boy would freeze before he froze right. Halloway had no gear for the deep cold or the broken ground along the river. He needed better. He needed men who had crossed that country and lived. So he turned his horse toward the Blackfeet camp. The teepees stood in a cluster near the trees, snow banked along their seams. A warrior worked a horse at the edge of the camp. He was tall and heavy through the shoulders, his black hair in two braids. He did not stop brushing the animal when Halloway reined in. Running Wolf. Halloway had traded with him twice. Both times the man had watched him like a slow storm. "Your soldier walked north," Running Wolf said. He did not look up. "Another one." "Two," Halloway said. "I need to follow. I came for gear. Snowshoes. Furs. A guide if you'll sell one." Running Wolf set the brush down. He led Halloway inside, where a fire burned low and old men sat along the hide wall. One of them began to speak. Running Wolf translated in a flat voice. "He says the thing in the north is not new. It ate men here fifty winters ago." Running Wolf paused. "A man who starves in the cold and eats the dead becomes it. The hunger never leaves him. He stops aging. He wears a soldier's coat, old, from a war before your war. He looks young. He looks human. He is not." Halloway kept his face still. Folklore. He had written that word in his report. But Daniel was gone, and now Tim walked the same trail. "I don't need the story," Halloway said. "I need to reach my man." Running Wolf stared at him a long moment. Then he nodded. He gathered a bundle: wide snowshoes, a heavy fur, strips of dried meat. He pushed them into Halloway's arms. "No charge," Running Wolf said. "You will pay in the north." Halloway strapped the gear to his saddle. "Guide me." "No." Running Wolf's jaw tightened. "My people do not walk toward it. We lost brothers to it. I will not lose more." He stepped close. "Your man who went three days ago is dead. The one you sent yesterday still walks. Ride hard and you may reach him before dark." Halloway mounted. The furs weighed warm against his legs. He had what he came for. He had no guide, and he carried a story he did not believe pressing against one fear he could not name. Running Wolf caught the bridle. "Soldier. The old uniform. If you see a young man in it, smiling, cold and alone out there—do not share your fire with him." Halloway turned the horse north. Behind him, the camp went quiet. Ahead, the river bent into the pines, and the mountain rose white and silent above the trees.

Halloway rode until the pines thinned and the river turned to ice. Snow lay deep over the grass, the frosted blades poking through like white hair. His horse balked. He dismounted, strapped on the wide snowshoes, and went forward on foot. Something dark broke the white ahead. He crossed to it and stopped. Bones lay half-buried in the drift. A skull grinned up at him, picked clean. Snow filled the ribs. Rags of a soldier's coat clung to one arm, the blue faded, the fringe torn. Halloway crouched. He could not tell the man by his face. The cold had taken that. He dug with his gloved hands until he found a strip of leather at the hip, and a book beneath it. The journal was swollen with ice. He pried the cover open. On the first page, in careful ink, a name: Daniel Crewe. Halloway shut the book. Three days of hope died in his hands. Running Wolf had been right. Daniel was dead, and he had died out here alone. There was no reason to search north anymore. The man he came for was bones. Then Halloway heard the scream. It came from up the slope, past a rocky rise. A man's voice, high and breaking. Halloway knew it. He had heard that voice every morning on the parade ground. Tim. Tim was alive, and Tim was screaming. He ran. The snowshoes slapped the drift. The rise opened onto a cave mouth cut into the rock, snow banked on the stone above it. The screaming came from inside, then stopped. The silence was worse. Halloway drew his saber and stepped into the dark. Cold air breathed out at him, sour with rot. His eyes adjusted. Tim lay on the ground, one leg twisted wrong, dragging himself back with his elbows. A shape crouched over him. It looked like a young man. It wore a coat older than Daniel's, the cut of a war before Halloway's war, the buttons dull. Its skin was pale and tight over the bones of its face. It turned and smiled at him, and its teeth were red. "Captain," Tim said. His voice shook. "Captain. It don't bleed. I cut it. It don't bleed." Halloway's mouth went dry. The story he had written down as folklore stood in front of him, smiling, cold and alone in the dark. A young man in an old uniform. Running Wolf's warning rang in his skull. "Come away from him," Halloway said. He raised the saber. His hand was steady. The rest of him was not. The thing in the old coat rose to its full height. It did not run. It stepped toward him, slow, still smiling, like a guest come for supper. Behind it, Tim screamed again for him to run. Halloway did not run. He planted his feet between Tim and the creature, and the dark closed around the three of them.

The creature moved fast. Halloway swung the old saber, and the rusted blade bit into its arm. No blood came. The thing hissed and drove its fingers into his side. Pain tore through him. Halloway staggered back against the cave wall. His hand pressed the wound. It came away hot and red. Tim shouted his name from the floor. The creature did not finish him. It stood over him and smiled with red teeth. When it spoke, its voice was dry, like wind over stone. "Montgomery Hemsworth," it said. "That was my name, once. Fifty winters I have eaten alone." It looked at Tim, then at Halloway. "I am tired, Captain. I would give this to another and die." Halloway held his side and said nothing. The thing crouched close. "Eat the boy. His flesh. His blood. The curse passes to you, and I am free to rot. Refuse, and I take you both tonight." It tilted its head. "Live forever, or die in this hole. Choose." Tim had dragged himself to the wall. His twisted leg bent wrong under him. He heard every word. His face was white, but his eyes were steady. "Don't," Tim said. "Captain. Don't you do it." He pressed his back to the stone. "I came out here for Daniel. I knew what might be waiting. You don't trade me. You don't." Halloway looked at the boy he had sent north alone. He had filed the creature as folklore. He had been wrong about everything but this. He would not be wrong about this. "No," Halloway said. The creature's smile dropped. "Then you both feed me." It lunged. Halloway was ready. He let his wounded side fold, dropping low, and brought the saber up with both hands. The rusted point took the creature under the jaw and drove up through its skull. The thing froze. Its pale fingers clawed the air. Halloway twisted the blade the way he'd been trained to twist it, and leaned his whole weight in. Steel was not enough to kill the old hunger alone. He knew that. But the Blackfeet said fire was the thing it feared. Halloway reached into his coat with his free hand and found the flint and the oil-soaked rag he carried for his lamp. He struck sparks against the rag until it caught. "Burn," he said, and pressed the flame to the creature's ancient coat. The dry cloth took like paper. Fire ran up the old uniform, over the pale chest, into the open mouth. The creature screamed, and the scream was almost a word. It beat at the flames and could not stop them. Halloway pulled the saber free and shoved the burning thing away, toward the back of the cave. It fell among the bones it had left there. The fire ate it down to black. Then it stopped moving, and the smell of old smoke filled the cave. Halloway dropped to his knees beside Tim. The wound in his side ran steady. He packed snow against it with a shaking hand. Tim gripped his arm. "You didn't do it," Tim said. "You didn't." He kept saying it, like he needed to hear it out loud. "No," Halloway said. "I didn't." He bound his wound with a strip torn from his shirt. Daniel was dead and buried in the snow outside, and there was nothing to carry home but his journal and his name. But Tim was alive. Halloway got the boy's arm over his shoulders and lifted him. The leg was broken, not the boy. They went out of the cave into the white glare. Halloway's horse still waited at the tree line. He set Tim across the saddle and walked beside him, one hand on the boy, one hand on his wound. The pines closed behind them. The cave and its black bones fell out of sight. It was dark when Fort Henry rose out of the snow, its timber walls and the flag stiff on the pole above the gate. Men ran out with lanterns. They took Tim down gentle and carried him to the surgeon. Halloway stood a moment in the open gate, bleeding and cold, and looked north at the country he had been sent to tame. He had written the creature off as a story. He had sent two men into it, and one came back. He would write the truth in his report this time, and let the officer who sent him here read it. Then he walked inside, and the gate swung shut against the dark behind him.
