Chapter 14: The Time-Wound Eraser

The drawer was locked, but it opened when Marguerite touched it.

She had been standing in the back room for twenty minutes, which Mr. Cog had allowed without comment. He had made tea, which sat cooling on the counter. She had not drunk it. She could not remember, at present, whether she liked tea. This was one of the smaller losses, barely worth noticing, except that it was hers and now it was gone.

The drawer was at the bottom of a cabinet so old its wood had gone grey. Marguerite had opened every other drawer in the shop over the past weeks — some searching for gadgets, some searching for answers, some searching simply to know what Grandmother had left behind. But this one had been locked, and she had not tried it until now. It opened with a small, apologetic click.

Inside was a pencil eraser.

Just that. Pink, ordinary, the kind you could buy for ten pence at any newsagent. It sat on a square of black velvet, attached to a thin silver chain, and it was warm to the touch. Not hot — warm, like something living, like a hand that had been held. Marguerite picked it up very carefully.

The label was underneath, in Grandmother's handwriting. The writing was steadier than in the final ledger entries, which meant Grandmother had made this years ago, back when she still knew who she was.

Time-Wound Eraser
Undoes one wound that time created. Death, loss, departure.
One use only.
Warning: Also undoes what grew in the wound's place.

Marguerite read it three times. Then she turned the label over. On the back, in smaller letters, almost as though Grandmother had added it later and hoped no one would notice:

If you're reading this, I didn't use it. Good.

Mr. Cog appeared in the doorway. He did not look surprised. He looked, if anything, resigned.

"You found it, then," he said.

"She made this."

"She did."

"And she never used it."

"No."

Marguerite closed her hand around the eraser. It was warm against her palm, patient, waiting. "Why not?"

Mr. Cog came into the room and stood beside her, looking down at the empty drawer. He was quiet for a long time. When he spoke, his voice was very careful, the voice of someone explaining something he has thought about for twelve years and still does not entirely understand.

"She thought about it," he said. "Quite often, towards the end. I would find her holding it, just holding it, not speaking. Once I asked her what she would undo, if she used it. She said there was only one wound worth erasing — the night she gave away all her certainty. The night you were born."

Something twisted in Marguerite's chest. She had stopped crying about that particular fact several days ago, but the grief had not gone anywhere. It had simply settled, heavy and permanent, like furniture.

"But if she'd used it," Mr. Cog continued, "she would have undone the sacrifice. She would have kept her certainty. She would still have been herself."

"And I would have died."

"Yes."

The word sat between them, small and absolute.

"So she didn't use it," Marguerite said. "Because using it would undo the repair she'd made. It would undo me."

Mr. Cog inclined his head. "That is one version, yes."

"What's the other version?"

He turned to look at her, and his face was sadder than she had ever seen it. "She could have used it to undo her own death. To bring herself back. But everything that grew from her absence would be erased. Including, possibly, you."

Marguerite felt the room tilt slightly. She sat down on the floor, still holding the eraser. It was still warm. Still patient. Still waiting.

"I don't understand."

"The wound the eraser undoes," Mr. Cog said gently, "is not the event. It is the absence the event created. If you undo your grandmother's death, she lives. But the absence of her — the grief, the inheritance, the shop passing to you, everything you have learned and lost and become in the weeks since you opened that solicitor's letter — all of it is erased. You return to the moment before the wound. Except you are also part of what grew in the wound's place."

"So if I use it to bring her back, I might—"

"Cease to exist. Yes."

Marguerite looked at the eraser. Pink. Ordinary. Ten pence at any newsagent. She wanted to laugh, but she could not remember, at present, whether she found things funny. That was another small loss, and it made her angrier than the larger ones.

"What if I used it to undo her sacrifice?" she asked. "Not her death. The sacrifice itself. Could I undo the night she gave away her certainty? Give it back to her? Let her have her life and her granddaughter and herself?"

Mr. Cog's face went very still. "You could. The eraser would work perfectly. It always works perfectly."

"But."

"But the sacrifice repaired your future. If you undo it, your future is un-repaired. You were born premature, Marguerite. Your lungs did not open properly. Without your grandmother's repair, you would have died in hospital three days after you were born. You would never have become this person standing here asking these questions."

Marguerite set the eraser down on the floor between them. It sat there, warm and patient, glowing faintly in the dim light of the back room.

"So both options lead to the same place," she said.

"I'm afraid so."

"If I undo her death, I might disappear. If I undo her sacrifice, I definitely disappear."

"Yes."

"And if I do nothing—"

"She stays dead. You stay alive. And you carry the knowledge that you could have tried."

Marguerite pulled her knees up to her chest. She was uncertain of a great many things these days — whether she was brave, whether her grandmother loved her, whether she could trust her own judgment, whether her father loved her — but she was absolutely certain of one thing: this was not fair.

"She never told you what she would have done," Marguerite said. "If she'd been me. If she'd found this after someone else had made the sacrifice."

"No," Mr. Cog said. "But she made it for you. She could have destroyed it. She could have hidden it somewhere you would never find it. Instead, she left it in a drawer that would open to your touch and no one else's. She wanted you to have the choice."

"I don't want the choice."

"I know."

They sat together in the back room whilst the afternoon light faded outside. Somewhere in the shop, the old pipes creaked. Somewhere further away, London carried on with its ordinary life — people catching buses, buying milk, complaining about the weather, living in a world where grandmothers died and stayed dead and you simply had to bear it.

Marguerite picked up the eraser again. Warm. Waiting.

"If I used it," she said slowly, "and I brought her back, and I disappeared — would she know? Would she remember me?"

"No. The wound would be undone. You would never have existed for her to remember."

"Would you remember?"

Mr. Cog was quiet. Then: "I don't know. I am... not entirely subject to ordinary rules. But I suspect not. The ledger would be different. The entries about you would vanish. It would be as though you had never been."

Marguerite thought about the ledger entries in Grandmother's shaking handwriting. Marguerite Tinker, age 0. Repair requested: future. The entry that had explained everything and broken her heart and made her angry and proud and grief-stricken all at once.

If she used the eraser, that entry would vanish.

Grandmother would never have written it.

Grandmother would never have needed to write it, because Marguerite would never have been born sick. Or Marguerite would never have been born at all. Or Marguerite would be someone else entirely, someone who had never stood in this shop losing certainty one repair at a time.

The problem, Marguerite realized with a cold, clear understanding, was not that the eraser didn't work. The problem was that it worked perfectly. It would do exactly what it promised. It would undo the wound.

It would just also undo her.

"Why did she make it?" Marguerite asked. "If she was never going to use it?"

Mr. Cog smiled, very small and very sad. "Because sometimes, knowing you could undo something makes it possible to bear. The grief is lighter when you know you're carrying it by choice."

"That doesn't make sense."

"No," Mr. Cog agreed. "But it's true."

Marguerite stood up. The eraser dangled from its silver chain, catching the last of the afternoon light. She looked at it for a long time. Then she put it back in the drawer, on its square of black velvet, and closed it. The lock clicked softly.

"I'm not going to use it," she said.

Mr. Cog let out a breath he seemed to have been holding for years. "I thought you might say that."

"Not yet, anyway. Maybe not ever. But—" She stopped. She wasn't sure how to explain this, even to herself. "But I need to know it's there. I need to know I could."

"That," Mr. Cog said, "is what your grandmother said. Twelve years ago, when she put it in the drawer and locked it."

They went back to the front room. The tea was cold. Marguerite poured it out and made fresh, and this time she drank it, though she still could not remember whether she liked it or not. It didn't matter. It was warm, and Mr. Cog had made it, and that was enough.

Outside, Puddling Lane was filling with evening shadow. The Monument rose in the distance, keeping watch over the city. Marguerite sat behind the counter with the ledger open in front of her — not reading, just looking at Grandmother's cramped, furious handwriting marching down the pages.

Worth it, the last entry said.

Marguerite traced the words with one finger.

She thought about Gripe, empty and drifting after the Regret Eraser took his grief. She thought about Mrs. Firth's son, who didn't remember breaking his promise. She thought about Tom Dredge, borrowing courage from his future self and having none left when he needed it most. She thought about the Friendship Glue that had held her and Pip to who they'd been instead of letting them grow into who they were.

Every gadget had worked perfectly.

Every repair had solved the wrong problem.

And the Time-Wound Eraser, she understood now, was the worst of all — because it would work perfectly too. It would undo the wound. It would bring Grandmother back, or restore Grandmother's certainty, or erase the sacrifice. It would do exactly what was asked of it, with absolute precision and perfect function.

It would just also erase everything that had grown in the wound's place.

Including love. Including grief. Including her.

Including, Marguerite thought, the certainty Grandmother had died with — that small, stubborn, shaking-handwriting certainty that it had been worth it.

"Mr. Cog," she said.

"Yes?"

"Do you think she would have wanted me to use it?"

He was quiet for a moment. Then: "I think she would have wanted you to have the choice. And I think she would have wanted you to choose yourself. She spent everything she had so that you could have a life. Using the eraser to undo that would be—"

"Ungrateful," Marguerite said.

"I was going to say 'a waste.' But yes. Ungrateful too."

Marguerite closed the ledger. She put it back on its shelf, next to the box of tags and the jar of pens and all the ordinary detritus of a shop that repaired impossible things at impossible costs.

"I'm not going to use it," she said again, to make it real. "Not to bring her back. Not to undo her sacrifice. Not for anything."

"Good."

"But I'm keeping it."

"Also good."

"Because she made it for me. And throwing it away would be like saying the choice doesn't matter. And I think — I think the choice is the only thing that does matter."

Mr. Cog smiled. It was the first real smile she had seen from him in all the weeks she'd been at the shop, and it made him look younger, less like a living ledger and more like a person who had loved someone very much and lost her and survived.

"Your grandmother," he said, "would be very proud."

Marguerite wasn't certain of that. She wasn't certain of much these days. But she thought it might be true, and thinking it might be true was close enough to certainty for now.

Outside, the evening deepened. The shops along Puddling Lane closed one by one, their lights going out like stars in reverse. Marguerite sat at the counter, drinking tea she couldn't remember liking, in a shop she hadn't known existed two months ago, mourning a grandmother who had loved her enough to forget who she was.

The Time-Wound Eraser sat in its locked drawer.

Patient. Warm. Waiting.

And she left it there.
