The name came again through the monitor, softened by distance and the hiss of brakes: Willow Halt. The grandmother’s fingers tightened on the photograph, and a little crease appeared across the empty seat. “There was a willow there,” she said, “though I don’t remember a station.” The child leaned against her knee, studying the pale place beneath the boy’s ink-stained hand, while the sleeper listened with her head turned toward the ceiling. Above us, a door slid open, and a draught came down through the boards, carrying the smell of rain on warm stone. On the monitor, the green door swung wider to reveal a strip of platform and the hem of the conductor’s coat.

The boy lifted his fingers from the photograph, leaving four dark marks on the indistinct shoulders, and a narrow line appeared between them. The grandmother brought the picture nearer the lamp; it was the edge of a sleeve, with a button at the wrist. She touched her own cuff, where a matching button hung by two threads, and looked at the child. “I mended that coat on the journey,” she said, “and someone held the cloth for me when the train shook.” The child put her hand over the grandmother’s, then reached for the clean ticket, but it was gone from where she had last held it. In its place, caught beneath the monitor’s frame, lay a thin strip of punched paper, and the Architect eased it free without tearing it.

There were four holes in the strip, and through them I could see the boards beneath, except at the last, where a small eye looked back at me. I dropped the paper; it landed beside the photograph, and the eye vanished as the strip turned over. From the platform came a knock, then another, then a third, each one making the coats on the floor stir at their collars. The boy stood very still, his hand pressed against the ticket sewn to his shirt, and the child moved beside him without taking hold of him. The fourth knock did not come, though we could hear something scraping at the green door, a slow, patient sound that raised a burr of paint along its edge. The sleeper took the lamp from the boy’s mother and held it toward the monitor, but the screen showed only the empty platform and a willow branch brushing the glass.

The grandmother picked up the strip and laid it across the photograph, fitting its holes over the dark marks the boy had left. Through the last hole, a button appeared, and beside it a hand resting on the younger child’s raised arm. The grandmother drew in her breath, then began to hum the tune Victoria had been singing; Victoria joined her, quietly at first, and the scraping stopped. A fourth knock sounded from beneath our feet, so close that the lamp flame bent, and the wooden panel lifted a finger’s width. The child crouched and slipped the photograph into the gap, keeping her palm flat until a small hand received it from below. When she drew back, the hand remained, its wrist emerging from a conductor’s frayed cuff, and the brass punch closed once in the darkness.

The grandmother put a hand to her throat, where the scarf still lay knotted beneath her chin. One end had caught in the sleeve of the nearest coat, and when she drew it free I saw that several threads had been pulled loose, fine as hairs. On the monitor, the key rested across the green threshold while the train gathered speed overhead, its wheels beating a rhythm through the boards. The boy who had come from the passage stood on tiptoe and touched the glass, but his fingers met only a cold reflection of the room behind us. The grandmother unwound her scarf and fed the frayed end into the seam beside the screen. The strand around the key tightened, and the key slid toward us with a faint metallic scrape.

It came through wrapped in a damp twist of wool, heavier than it looked and warm on one side, as though it had been held for a long time. The grandmother laid it in her palm, and the child leaned close to examine the teeth, where a fleck of green paint had caught. “The door?” the boy asked, but the Architect shook his head and pointed to the girl’s paper. Around the painted lock, the little footprints had begun to separate, leaving a narrow white path to its edge. The girl placed the paper on the floor and set the key upon it; for a moment nothing happened, then the lock showed faintly through the metal, its outline no wider than a thumbnail. The sleeper crouched beside them, keeping one hand on the boards as the train passed above.

When the grandmother turned the key, the paper twisted with it, and a sharp crack ran through the wooden panel over the passage. The boy caught at the child’s sleeve, but she shook her head and knelt with him, pressing both hands on the panel where the sleeper had pressed hers. Water welled through the crack, bringing with it a smell of wet wool and old iron, and the coats around us began to lift at their collars. The sleeper reached for the key, then stopped as the child looked up at her. “I can hold it,” the child said, her arms trembling with the effort. Together the grandmother and the girl turned the key the rest of the way, while Marcus counted the strokes of the wheels and Victoria held a single note until the panel settled beneath the child’s palms.

The water drained back through the crack, leaving a small square of paper on the wood, its edges neatly serrated. It was a photograph, though at first I took the pale shapes in it for another row of empty coats; then the boy’s mother lifted the lamp, and I saw faces turned toward a window, the grandmother among them with her scarf bright against her dark dress. Beside her sat the child, younger than she was now, her hand raised against the glass. Behind them stood a figure in a conductor’s coat, holding a brass punch, but its face had been rubbed away so thoroughly that the paper had worn thin. The grandmother touched the seat opposite her own, where the upholstery showed between two indistinct shoulders. “There was someone there,” she said, and the boy from the passage put his stained fingers over the empty place. Above us, the train slowed, and through the monitor’s open green door came the clear call of a station name none of us had spoken.

The first hole appeared with a soft pop, and a bead of water slid down the monitor’s face. The boy touched the four holes in the ticket sewn to his shirt, counting them without moving his lips, while the child held the clean ticket out between them. In the bright pane, a dark point pressed against the glass again; the second hole opened beside the first, and somewhere above us the train bell answered. The Architect reached for the monitor’s cord, but the sleeper caught his hand before he could pull it free. “Wait,” she said, and bent to gather the empty coats, laying them one over another with their sleeves turned inward. The grandmother helped her, smoothing each collar as though someone still wore it.

When the third hole appeared, the boy who had come through the passage stepped close to the screen and put his palm against the damp glass. His hand was small beside the pane, but the dark point withdrew from it, leaving a pale ring around the unfinished row. “They’re making a ticket,” he said, and the child looked down at the one she held. She placed it against the outside of the pane, beneath his hand, and the three holes showed through the paper as bright circles. Behind the glass, a figure shifted in the lamplit room, too near the pane for us to see more than the cuff of a sleeve and a brass punch held in its fingers. Victoria’s song faltered, and the figure paused, its tool poised where the fourth hole should have been.

The boy’s mother set the lamp beside the monitor, and its warmth slowly cleared the mist from the glass. The figure wore a coat like the ones on the floor, with a frayed cuff and a loose button that knocked against the pane whenever its hand moved. The child pressed the ticket harder against the screen, but the boy pulled at her sleeve. “If it finishes, you have to go,” he said, and she turned to the sleeper, who had come to stand behind them. For a moment the sleeper’s hand hovered above the child’s shoulder; then she rested it there, lightly enough that the child could step away. “You waited for me,” she said. “This time I’ll listen.”

The child drew the ticket back, leaving three wet circles on its surface, and offered it through the open seam between the monitor and its frame. The figure’s fingers closed around the paper, and for an instant the brass punch hung motionless against the glass. Then it descended on the ticket instead, piercing the fourth hole with a crisp sound that made the boy flinch. The bright pane went dark, and all around us the coats gave a small rustle, their pockets settling flat; from above came the long scrape of a train beginning to move. On the screen the green door remained open, and the figure stepped away from it carrying the punched ticket, its loose button flashing once in the lamplight. Before the door could close, another hand reached through and left a key on the threshold, its teeth wrapped in a strand of the grandmother’s scarf.

The step stopped just beyond the lamplight, and the tickets hanging along the passage settled one against another. The boy’s mother drew him close, but he leaned forward, holding out the lamp until its warmth reached the edge of the wooden panel. A hand emerged first, small enough to fit the print on the girl’s paper, with four fingertips stained black. Behind it came a boy in a coat much too large for him, its hem trailing through the water between the boards. He looked at the child beside the sleeper and touched his fingers to the dents in the panel. “I knocked four times,” he said, “but she only heard three.” The child lowered the paper and stared at him, her hands tightening around its damp corners.

The sleeper moved aside to give him room, though he remained in the passage, looking past her at the roll of tickets in my hand. When I offered it to him, he shook his head and pointed instead to the ink on my thumb. In the lamplight I could make out a line of tiny writing there, reversed and blurred where my skin had creased. The girl pressed her paper against it, and when she lifted it away, a name had transferred beneath the second handprint. The child bent close enough for her scarf fringe to brush the page, then spoke the name so softly that I nearly missed it. The boy stepped over the threshold at once, leaving a dark print on the board, and the bell overhead gave a single, uncertain stroke.

His coat caught on a nail as he came through, and the grandmother freed it while the sleeper held the panel open. Beneath the coat he wore a shirt with a paper ticket sewn to its front, the stitches uneven and dark with age. He covered it with his hand when the Architect reached toward him, but the child took his other hand and waited until he let her see. The ticket bore no name, only four little holes punched in a row; behind us, the panes on the monitor lit one by one, showing coats filling the passage where he had stood. “They couldn’t come through while I was there,” he said, and the boards shuddered beneath our feet. The sleeper pulled the child against her side, then caught the boy by his sleeve as the passage began to narrow.

Victoria’s song rose above the creaking, and Marcus counted with her while the Architect braced both hands against the panel. The boy tugged free long enough to press his four stained fingers to the girl’s paper, directly over the print that had appeared there, and the hanging tickets ceased to flutter. One by one, the coats slipped forward into the chamber, falling flat and empty around our feet, until the strain left the wood and the Architect could lower the panel gently into place. The child knelt beside the coats, feeling through their pockets as if she expected to find hands tucked inside; from the last one she drew a small, unpunched ticket, clean and dry. She offered it to the boy, but he looked up at the monitor instead. In the single bright pane, someone had begun to punch four holes in the glass from the other side.

The child tucked her chin against the sleeper’s shoulder as the green door opened on the monitor, revealing the lamplit room. One by one, its panes brightened, though no flames appeared behind them, and in each glass I saw the chamber from a slightly different angle. The boy came forward and offered the child the warm lamp; she touched its cracked globe, then drew her hand away when the bell sounded again. “It’s calling them,” she said. Her voice was rough from disuse, and the sleeper shifted her higher, keeping one palm spread across the child’s back. The Architect bent over the open floor, where the folded coats had begun to lift and settle in a wind none of us could feel.

The girl picked up her paper and held it over the gap, but its footprints stayed where they were, crowded around the painted lock. Beneath them, a second handprint slowly emerged, smaller than the first, its fingers curled as though gripping an edge. “I held the boards down,” the child said, watching it appear. “You told me to wait until the knocking stopped.” The sleeper’s hand grew still on her back; then she lowered herself to sit beside the opening, bringing the child down with her. “I heard you,” she said, after a while, “but I couldn’t find the way back.” The child studied the dark space between the boards and rested her hand on the sleeper’s knee.

A scrape came from beneath the coats, followed by three knocks in quick succession, and Marcus’s tenth voice counted them before falling quiet. The boy knelt opposite the sleeper, waiting for the fourth, while his mother held the lamp low enough for its light to reach under the boards. I saw the coats stir apart and a narrow passage beyond them, its walls hung with ticket stubs that fluttered against one another with a dry, papery sound. The fourth knock came from deeper inside, and the child pressed both hands over her ears as the panes on the monitor flashed white. The sleeper reached into the gap, found the edge of a coat and pulled it free; beneath it lay a wooden panel with four shallow dents, each worn pale at the center. She laid her palm against them, and the knocking stopped.

For a moment we heard only the lamp hissing and Victoria breathing between notes of her song. Then the panel eased outward under the sleeper’s hand, and a little roll of tickets spilled through, damp and tightly bound with wool. She passed it to me, but when I tried to lift the outer ticket, the paper clung to the one beneath it, and the ink began to run over my thumb. On the monitor, the lamps went dark except for one pane, where a hand appeared, its fingertips leaving four clear marks on the glass. The child stood with the sleeper’s help and took the girl’s paper, turning it so that the small handprint faced the screen. “That isn’t mine,” she said, and from the open passage came the sound of someone taking a careful step toward us.
