The line inside the watch curved toward its rim, and the older woman stopped beneath the porch, sheltering it with her hat. Up close, her face had the familiar crease beside the mouth, but her hair was almost white where the rain had loosened it from its pins. My mother stepped outside without her coat and stood before her, leaving the door wide enough for me to watch. “Did you wait on the train all this time?” she asked. The woman shook her head, and a bead of water fell from her chin onto the watch glass. “I waited at the door,” she said, “until I could remember which side you were on.” Behind me, my older self came down the stairs slowly, one hand sliding along the banister.

The conductor reached the hall as the woman held out the watch, but when he tried to take it, the line tightened into a blue loop around the minute hand. He drew back, and my father, who had followed with the box, set it open on the table beside the door. The ticket lay inside with its corner fitted neatly in place, though a dark seam still divided the two pieces. “The list has room for her,” the conductor said, unfolding it again, “but she must be named by someone who came for her.” My older self looked at my mother, then at the woman beneath the porch light, whose fingers had begun to shake around the watch. “I came back,” they said, and the older woman lifted her eyes to them. “I know,” she answered, “but you didn’t come back alone.”

My mother took the watch from her then, cupping it between her palms as she had cupped my cold hands on winter mornings. The blue loop loosened, and from upstairs came the scrape of the chair, followed by the boy calling for us to wait. He appeared at the top of the stairs with Elsie and the woman, the length of thread stretched between their hands; as they descended, it paid out behind them, slipping from the closed window without breaking the latch. The older woman put out a finger, and the thread wound itself around it once, leaving a thin blue mark in her skin. My older self crossed the threshold and stood beside her, close enough that their sleeves touched. “I left my mother at the door,” they said, and this time they did not turn away. On the conductor’s list, the hidden name darkened completely, and my mother read it aloud.

The watch began to tick again, softly at first, while the older woman stepped into the hall and let my father close the door against the rain. My mother took off her wet hat and hung it on the peg, then reached for the other hat and placed it beside her own. For a little while nobody moved; even the boy stood still, his mitten resting on the banister, while the conductor folded the list and put it away. Then a bell sounded from the train beyond the garden, and the thread slipped from the older woman’s finger, drawing a blue line across the floor toward the letterbox. Something thin passed through the brass flap and fell onto the mat. I picked it up before the water beneath it could spread, and found a fresh ticket, whole except for one torn corner, with my mother’s name written on the back.

The figure in the carriage doorway raised its hand a second time, but the knock reached us from inside the room, beneath the chair. The boy climbed down at once, leaving the wet print on the seat, and my older self caught the chair before it rocked against the wall. “Who did you leave?” I asked them. They kept looking toward the train, where the figure stood with rain running from the brim of a hat I recognized as my mother’s. My mother came to the window and laid her hand over mine, and the figure lowered its arm. “She stayed aboard when I came here,” my older self said. “I shut the window and went home without her.”

Downstairs, the conductor’s watch stopped ticking. He appeared in the doorway with the list unfolded, and my father followed him, carrying the box against his chest as though it contained something that might wake. The conductor held the paper toward the light; beneath the boy’s name was a blank line, and below that a second name had begun to show through, letter by letter, in the same careful hand as mine. My mother leaned forward, but my older self folded the bottom of the list back before she could read it. “You said there was time to close the window,” they told the conductor. “You didn’t say what would be left on the other side.” He glanced at the latch, then at the train. “I didn’t know you had brought her with you.”

The woman took the blue thread from the sill and passed one end to Elsie, who held it without being asked. Together they stretched it across the room; it reached the door but no farther, although the loose end continued to tremble in Elsie’s fingers. The boy put his mitten beneath it, and a drop of black water fell onto the floorboards, followed by another, until they made a trail toward the stairs. My father set down the box and opened it, revealing the pale square of the ticket inside, clean except for the crooked mark where my name had begun. He looked at my older self. “You put it back?” They nodded, and he fitted the missing corner into its place; the word TOMORROW vanished beneath his thumb, while outside the figure stepped down from the carriage.

My mother moved toward the stairs, but my older self stood in her way, their hand braced against the doorframe. “I heard her call after me,” they said, “and I kept walking because I thought the door would close if I turned around.” My mother touched their cheek, then slipped past them and followed the black drops down to the hall, with me close behind. At the front door she paused only long enough to lift the latch; cold air entered, smelling of wet soil and the iron rails beyond the gate. The figure was halfway up the garden path now, carrying the empty watch open in both hands. As it came beneath the porch light, I saw my mother’s face under the hat, older than either of us remembered, and on the watch glass a fresh line was appearing, drawn from within.

She tapped twice against the pane, and the answer came at once from the open window above the garden: one knock, followed by the faint scrape of a chair. The train had stopped with its doors still shut, and rain gathered along the outside of the glass, blurring the white gate. Elsie stood beside the woman and pressed her forehead to her arm, watching the curtain lift and settle. “I thought you had forgotten,” the woman said, so quietly that I could not tell whether she was speaking to the boy or to the room. He put on the mitten again and held out his covered hand, but she took his bare one instead. My name remained on the pane above them, each pencil stroke darkening as the light outside grew thin.

The conductor came down the aisle with his watch in one hand and the folded list in the other, stepping over the box my father had placed between his feet. “There is time to close it,” he said, looking toward the house, “but the person expected must go to the window.” My mother reached for my coat before I could move, pulling its collar straight beneath my chin as she had done that morning, though her fingers would not stop trembling. My older self opened my hand and looked at the ticket corner lying there, the word TOMORROW faint beneath a smear of black. “I kept it once,” they said. “I thought if I never gave it back, tomorrow could not arrive.” They did not tell me what had happened instead, but when the conductor tried the carriage door, they were the first to follow me onto the wet gravel.

The garden smelled of turned earth and rain, and the path to the house was bordered by rows of flattened flowers, their petals caught against our shoes. Wren carried the box while my father held an umbrella over us, though the wind pushed the rain beneath it and soaked the boy’s hair. At the cream door the woman stopped, her hand on the latch, and asked Elsie to stay with my mother; Elsie shook her head and took hold of her sleeve. Inside, the stairs creaked under our weight, and through the open upper window came the steady sound of water dripping from the sill. The chair stood beneath it as it had in the glass, but no one sat there now, and a small wet footprint marked the seat. The boy climbed onto it and reached for the window, only to draw back when the curtain lifted and a hand appeared outside, blue thread wound around one finger.

I put the ticket corner on the sill, and the hand closed over it before I could decide whether to let go. The boy caught the loose thread with his mitten, pulling hard enough to strain the stitches, while the woman leaned past him and drew the window down; for a moment the sash held against the wrist, and then the hand slipped away, leaving the corner behind. The latch dropped with a small, ordinary click, and downstairs the conductor’s watch began to tick so loudly that we could hear it through the floor. My mother gathered me against her, and the boy, still standing on the chair, unwound the thread from his mitten and laid it carefully beside the ticket. On the other side of the glass, rain washed the garden clear, revealing the train waiting beyond the gate with its carriage doors open. A figure was standing in one of them, and when it raised its hand to knock, my older self stepped back from the window and said, “That was where I left her.”

The scratching stopped after the first letter, a crooked mark that might have belonged to either name. The boy stood on tiptoe to see it, his mitten pressed against his chest, while the conductor held the open watch beneath the ticket. The blue loop shifted under the watch glass, though his hands were perfectly still. “It can’t finish without the corner,” my older self said, and my father shut the box before anyone could reach inside. The woman bent to the boy and asked him what he remembered of the room. He rubbed the mitten’s cuff between his fingers and said, “The chair was for her, when she came to shut the window.”

The woman looked at the glass, where only our carriage was reflected now, and then at Elsie beside her. “I used to wait there until you were asleep,” she said, though I could not tell which of them she meant. Elsie took the woman’s hand and turned it over, studying the damp crease across her palm as if she might find an answer there. The conductor slipped a fingernail beneath the watch glass, but my older self caught his sleeve. “If you let it out, will the window open again?” they asked. He closed the watch without replying, and from the ticket came another slow scrape.

My mother reached past me and tried to peel the ticket from the pane, but the black bead spread beneath her thumb, fastening it more firmly. The boy climbed onto the seat beside her and held up the mitten, its loose thread dangling toward the sill. Before anyone could stop him, he laid the cuff against the unfinished letter, and the thread passed through the glass as easily as a needle through cloth. The carriage gave a long shudder; outside, the gardens returned, slipping past in the opposite direction, their open gates flashing white in the rain. Wren caught the boy’s ankle as he leaned forward, and I took his other hand, feeling the cold water squeeze from the wool onto my wrist. On the pane, the crooked mark lengthened into a name I knew: mine, written in the careful hand my mother had taught me.

The conductor pulled the list from his coat, and for the first time the space beside the boy’s name was dry. “He has his place,” he said, folding the paper, “and yours is waiting.” My mother drew me away from the window, but I kept hold of the boy until he stepped down beside Wren; then my older self came close and pressed something into my palm. It was the ticket’s missing corner, taken from the box while we had all been watching the glass, and on its underside the word TOMORROW had returned. The train slowed beside a garden gate, and beyond it the upper window stood open once more, its curtain lifting into the grey air. This time the woman rose before anyone else, and when the knock came, she answered from inside the carriage.

Wren tapped once more, and the figure lowered its arm. The window in the reflected room stayed open a hand’s breadth, admitting a strip of grey light that fell across the empty floor. “You can answer it?” I asked, but Wren only put their palm against the glass and waited. The boy took the pencil from the list and laid it beside Wren’s hand, its point directed toward the room. A second knock came from the other side, and the pencil rolled beneath his fingers, leaving a thin black line on the window. My older self caught my wrist as I reached to touch it, then let go when they saw the line had stopped at the edge of Wren’s palm.

The conductor unfolded the list, keeping the mitten over the words beneath the boy’s name. “Two from here, one from there,” he said, and tapped the rhythm against his watch. The woman looked up sharply, her hand closing around Elsie’s. “That was how I called him in from the garden,” she said, and the boy turned toward her, his bare foot leaving a damp mark on the seat. She tapped twice on the glass, more gently than Wren had, and the figure in the chair rose. For a moment its head was lost above the frame of the carriage window; then it bent and placed a small hand on the reflected sill, with blue thread wound around one finger. The boy held up the mitten, and the loose loop at its wrist trembled.

My mother tried to pull him back, but he slipped down from the seat and stood with his face close to the glass. “You were waiting for me,” he said, and the figure turned enough for us to see the edge of its cheek, pale against the dark room. The woman made a sound and pressed her knuckles to her mouth; my father steadied the box as the carriage began to sway. The boy laid the mitten against the window, and water ran from it in a narrow stream, tracing the seam between the frame and the wall. When the figure reached through the reflected opening, the glass bowed inward beneath its hand, and my older self seized the mitten by the cuff. The blue thread pulled taut between their fingers and the figure’s, drawing the boy forward until Wren caught him around the waist.

I took the ticket from my pocket and pushed its blank square against the thread. At once the figure’s hand stopped, and the carriage lurched so hard that I fell against my mother; the ticket remained on the glass, held there by a bead of black water. My older self eased the mitten back, and the thread slipped free, leaving the figure standing at the open window with its hand raised. The room faded as the carriage straightened, but the ticket did not fall, and behind its pale square something began to scratch. The conductor opened his watch at last, and we saw that its face was empty except for a small blue loop caught beneath the glass. “Keep the mitten,” he told the boy, while the scratching continued, slowly forming the first letter of a name.
