The key turned a second time, and the desk shifted against the keeper’s knees. Marcus waded forward to help, but the keeper put out an arm and told him to leave it where it was. A seam had opened in the floor beneath the desk, and through it came a thin current carrying scraps of blue paper. The boy knelt and caught one against his palm; when he lifted it, we saw a fragment of a timetable with the edge of a station name still visible. The conductor took it from him and held it toward the light from the high window, but the water had softened the print beyond reading. Minnie kept her sister’s label above the surface while the child pulled gently at the thread between their fingers, drawing her attention back to the seam. Something on the other side knocked once, then waited.

The keeper moved the stones from the ledger and turned several pages, their wet fingertips leaving blue crescents on the paper. “Your sister signed for a passenger,” they said to Minnie, stopping at a line ruled through in ink. Beside the line was a date matching the one on Minnie’s label, and beneath it a signature with the same long, slanting strokes as the note. “Who was it?” Minnie asked, but the keeper shook their head and showed her where the name had been scraped away. The conductor bent over the page, its scarf trailing in the water, and touched the damaged paper with unusual care. “Someone wanted the journey recorded,” it said, “but not the person who made it.” At that, the child held up the little glove, and the keeper’s gaze dropped to its empty cuff.

Water pressed up through the seam until the floorboards trembled. The boy took the key from his pocket and looked at the mark on his palm, where the blue had begun to spread into the lines of his skin. Before anyone could stop him, he pushed the joined tooth into the narrow opening; there was a click, and the desk lurched aside. Marcus caught the ledger before it fell, while Victoria seized the lamp and raised it over the water. A square hatch lifted beneath the desk, bringing with it a rush of cold air and the smell of soaked wool. Minnie dropped to her knees and reached into the darkness, the red thread pulling taut as the child leaned beside her. A hand took Minnie’s wrist, and she held on as a woman’s face rose slowly through the water, her hair plastered across one cheek.

Minnie brushed the hair aside, though her own hand was shaking too much to do it neatly. The woman opened her eyes at the touch and looked first at Minnie, then at the child and the glove between them. “I left you a note,” she said, her voice catching as Marcus helped her onto the floor. Minnie drew the folded paper from her coat and pressed it into her sister’s hand, but her sister only closed her fingers around it and stared at the open hatch. Below us, in the place she had come from, the hollow strokes of an oar had begun again. “I locked the door,” she whispered, as the keeper hurried to lower it, “because something was following me.”

The cart began to move at the second stroke, its wheels following the rails into the trees while the lamps at Willow Halt dwindled behind us. The conductor stood at the rear with one hand on the pole, watching the dark gather where the platform had been. Water soon covered the sleepers, then the rails themselves, though the cart rolled on beneath it without a ripple. Marcus drew the child’s feet onto the seat, and she leaned against Minnie, keeping her finger crooked so the red thread would not slip free. Ahead, the trees opened onto a broad stretch of water in which the last light of morning lay strangely motionless. The oar sounded again, and a low roof emerged from the mist, its chimney just above the surface.

A narrow landing projected from the roof, and there the cart stopped beside a boat whose bow was tied to an iron ring. The person we had seen in the water stood in it, holding the oar upright; their rolled sleeves were dry, but blue ink had gathered in the creases of their hands. “The label,” they said, and Minnie took the folded note from her coat without opening it. The keeper held out a hand, but the boy caught Minnie’s sleeve with his uninjured fingers. “You pulled me,” he said, showing the blue mark across his palm, and the keeper lowered their eyes to it. “I thought you were the one they had sent,” they answered, and laid the oar across the boat to make room for us.

Inside, the upper room was reached through a trapdoor in the roof, with the floodwater standing a few inches below its sill. Books floated against the shelves, their pages spread like pale fins, and on the desk lay a ledger held open by two stones. The keeper took Minnie’s label and placed it over a blank space on the page; as the paper touched it, a name appeared in the child’s small, uneven hand. Minnie bent close, but the letters blurred under the water that rose suddenly through the floorboards. The keeper pressed the label down with both palms, and the knocking we had heard beneath the platform began again, this time from under the desk. The child slipped from Marcus’s grasp and knelt beside it, calling softly, “I’m here,” while Minnie held fast to the thread between them.

The knocking stopped, and a little glove floated out from beneath the desk, its fingers dark with ink. The child reached for it, but Minnie caught her wrist; for a moment they both held still, looking at the glove as it turned slowly in the rising water. Then the child took Minnie’s hand and guided it down until they lifted the glove together, water streaming from its empty cuff. Beneath it, caught in the grain of the floorboards, was a second label bearing the same fingerprint and the name of Minnie’s sister. The keeper stared at it, their fingers loosening on the ledger. “She was collected,” they said, and from somewhere below the flooded room came the hollow scrape of a key turning in a lock.

The three lights came on together, moving between the rails with a slow, uneven sway. As they drew nearer, we saw that the lowest belonged to a handcart, its iron wheels turning without a sound, while the others hung from poles at either end. There was no one pushing it; a coil of wet rope lay in the bed beside a long wooden oar. The conductor backed against the cabinet and kept one hand on its door. “It shouldn’t have come this far,” it said, though it reached out when the cart stopped and caught the nearest pole to steady it. Water dripped from the axle onto the dry boards, and the child in red crouched to touch the spreading dark patch.

A luggage label was tied beneath the cart’s handle, its thread knotted so tightly that Marcus had to loosen it with the point of his knife. On the label was written STILLWATER, and below it, in smaller letters, *Return the passenger before the lamps go out.* Minnie read the words twice, then turned toward the cabinet, where her own label hung motionless behind the glass. “They mean me,” she said, but the child shook her head and held up her damp fingertip. It fitted the ink impression when Minnie opened the cabinet and brought the label close, though the conductor caught her wrist before she could lift it from its hook. “A name can be put on the wrong thing,” the conductor said, looking not at Minnie but at the child.

The boy climbed into the cart and found a shallow pool beneath the rope, clear enough to show the grain of the wood. When he dipped the key into it, the water stirred, and a little square of reflected sky gave way to the image of a flooded room: shelves, a high window, and a person seated at a desk with their sleeves rolled above the elbows. The person looked up as if they had heard something, and the child called out before Minnie could stop her. A hand rose through the water and closed around the boy’s injured fingers; he cried out, and Marcus caught him about the waist while Victoria set down the lamp and gripped his other arm. Minnie leaned into the cart, the red thread stretching from her finger to the child’s, and pressed her sister’s note against the water. The hand released him at once, leaving a blue mark across his palm, and the note floated for a moment on the surface before the image vanished.

Minnie unfolded the wet paper, but the original message had not washed away; beneath it, in the same slanting hand, a new line had appeared: *Bring the label, not the child.* The conductor read it over her shoulder and went back to the cabinet, where it stood for some time with its fingers resting on the glass. At last it opened the door and untied the label itself, bracing for the knock beneath the platform, but no sound came. Minnie tucked the label inside the note, and Marcus lifted the child into the cart beside the coil of rope; the boy followed, holding his marked hand close to his chest. As the rest of us climbed aboard, the lamps at Willow Halt began to go out, and far down the track we heard the first hollow stroke of an oar.

The name on the tag was STILLWATER, though the last two letters had bled into the brass where the boy’s injured hand touched them. Victoria brought the lamp close, and the conductor read the name with one finger following beneath it. “There used to be a stop there,” it said, “before the water came up.” The timetable was still on the shelter floor; Marcus picked it up and found a blank space between Willow Halt and the next printed station, wide enough for a name that had been rubbed away. Minnie tucked her sister’s note inside her coat, taking care not to disturb the thread around her finger. When the boy offered her the key, she folded his hand over it instead and asked him to keep it until they knew what it opened.

They crossed back to the platform while the lamps burned steadily in the brightening air. The rails were slick, and Marcus carried the child in red over the second one after her shoe slipped against the iron. At the clock, the conductor stopped beside a locked wooden cabinet that none of us had noticed earlier; its glass front was filmed with dust, but behind it hung rows of luggage labels, each tied with a different color of thread. The boy tried the key, and the cabinet opened without resistance, releasing a smell of paper and river mud. Most of the labels were blank, though one near the bottom bore Minnie’s name in the same blue hand as the note. She touched it, and from somewhere beneath the platform came a soft, familiar knock.

The child climbed down from Marcus’s arms and held the lamp while Minnie untied the label. Its reverse was marked with a date and the words *ONE PASSENGER UNCOLLECTED*, and beneath these was a small impression, as if someone had pressed a fingertip into wet ink. Minnie set her own finger over the print, but it was too small for hers; the child put out her hand, then drew it back when the cabinet doors began to swing shut. Marcus caught one door against his shoulder, and Victoria took the label from Minnie before it could be trapped between the panels. The knocking quickened below us, followed by a scrape that traveled along the boards toward the edge of the platform. “Give it back,” said the conductor, and when Victoria slipped the label onto its hook, the cabinet fell still and the sound beneath us ceased.

For a while no one moved, though the lamp flame steadied and a bird began calling from the wet trees beyond the track. Minnie took the child’s hand and looked at the label through the glass, her thumb resting on the pale crease of her little finger. “Was it her they left there?” she asked, and the conductor pulled its scarf close before answering that it did not know. The boy turned the key over, examining the joined tooth, and found a line of blue ink newly visible along the edge of the tag: *Ask for the keeper at Stillwater.* Far down the track, a light appeared between the trees, too low and slow to be a train, and beside it another light rose from the ground. As we watched, a third flickered on, and the conductor backed away from the platform edge.

The glove rose by its fingertips, dragging the timetable from the case before it fell open on the shelter floor. For an instant its empty palm faced the grandmother, and she reached down as if to take it, but the child caught her sleeve. On the other side of the glass, the girl had begun pulling at the red thread, unwinding it from the glove the porter had given her. With each turn around her finger, the glove in the case grew stiller, until at last it lay flat among the comb and the yellowed lining. The clock continued backward, its hands passing noon, then eleven, while the darkened letters above it shed fine black flakes onto the platform. “You must stop it,” Victoria said, but the conductor only stooped to gather the timetable, its small hands trembling against the damp paper.

The girl pressed the unwound thread to the glass, and the child in red put her little finger against its end. A red loop appeared around it, loose enough to slip over the knuckle, and the grandmother bent to untie it; the child gently pushed her hand away. “I remember the clock,” she said, watching the girl through the pane. “I couldn’t see it from the bench, so she tied this on me and said she’d find me even if I went to sleep.” The girl nodded, though her eyes remained on the grandmother, and the porter took off his cap and held it against his chest. Minnie smoothed the child’s wet hair back from her forehead, then laid her palm against the glass between the two small hands.

The window shuddered, and a crack ran from the broken tooth beneath the bench to the place where Minnie’s hand rested. Through it came the smell of warm bread and coal smoke, so sudden among the wet wood and moss that the boy lifted his head. “Come through,” Minnie said, but her sister shook her head and pointed past them, toward the rails. There, beyond the shelter door, the dark platform was receding as though carried away on an unseen train; Marcus caught the doorframe, and Victoria’s lamp swung, throwing their shadows across the glass. The conductor seized the broken key from the boy and fitted its jagged end into the slot, but it would not turn until he put his injured hand over the conductor’s and pressed with all his weight. The key moved with a sharp click, and the platform stopped slipping, though the crack in the window widened enough to admit a thin, bright blade of morning.

Minnie’s sister slid her fingers into the opening and passed the note back through, folded now around the red thread. “You can find me,” she said, and Minnie took the paper, holding it close as the glass began to cloud. The porter lifted the leather case from his side of the window, and when the mist cleared, he and the girl were gone; only the clock remained, ticking forward again beneath its blackened sign. The child drew the thread from the note and tied it around Minnie’s finger, making the knot clumsy but firm. Outside, the rain had stopped, and along the opposite platform lamps were coming on one by one, although the sky above the shelter was brightening. The boy pulled the key from the slot and found the lost tooth joined to it once more, with a small new tag hanging from the bow. On the tag, in the same slanting blue hand as the note, was written the name of a station none of us recognized.
