Chapter 12: What Grandmother Knew

Marguerite had seen Mr. Cog make tea three times before, but she had never seen his hands shake.

They shook now, just slightly, as he filled the kettle. He did not look at her. He set the kettle on the small electric ring in the back room, found two cups (one with a chipped handle, one with a faded pattern of roses), and arranged them on the counter with the sort of care usually reserved for objects that might break if handled too roughly. Which was, Marguerite realised with a twist in her stomach, precisely what was happening. Mr. Cog was treating her as though she might shatter.

"I want to know everything," she said, because silence felt worse than speaking. "No more half-truths. No more 'conversations for another day.' I want to know what Grandmother did."

Mr. Cog's shoulders sagged, just a fraction. He was a small man — shorter than Marguerite's father, though considerably tidier — and when he sighed, it seemed to come from somewhere much larger than the space he occupied.

"Yes," he said quietly. "I rather thought you might."

The kettle began to hiss.

---

They sat in the back room, where the shelves climbed the walls in a geometry that defied any sensible building code, and Mr. Cog told her the story from the beginning.

Eudora Crawe had discovered her ability quite by accident when she was twenty-three years old. She had been living in a flat in Islington — a perfectly ordinary flat with mould on the bathroom ceiling and neighbours who played music at inconvenient hours — when she found a music box in a junk shop on Upper Street. It was broken. The spring inside had snapped, and the ballerina no longer turned. Eudora, who had no particular skill with mechanics but a great deal of affection for broken things, had taken it home and wished, very hard, that it would play again.

It did.

The cost, which she did not notice until three days later, was that she could no longer remember her favourite song. She knew she had once had a favourite song — the ghost of it lived somewhere in the back of her mind — but when she tried to recall the melody, there was only a sort of hollow space where certainty should have been.

"She thought she was going mad," Mr. Cog said, and his voice was very steady, as though steadiness was the only thing holding the words together. "She tested it. Fixed a cracked teacup. Lost her certainty about whether she preferred Earl Grey or English Breakfast. Repaired a child's broken kite. Lost her certainty about whether she was afraid of heights."

"And she kept going," Marguerite said. It was not a question.

"She did." Mr. Cog took a sip of his tea, which was still too hot, and set it down carefully. "Because she discovered that the repairs were not random. They were impossible repairs. The sort that ought not to work. A clock with no mechanism. A photograph torn so badly the faces were unrecognisable. A promise that had been broken for twenty years. She could fix them all. And the costs — well. She thought, at first, that they were manageable."

The kettle had stopped hissing. The back room was very quiet.

"How long?" Marguerite asked. "How long did she do this before—" She could not quite finish the sentence.

"Fifty years," Mr. Cog said.

Fifty years. Marguerite tried to imagine it and could not. Fifty years of fixing impossible things. Fifty years of losing pieces of herself, one repair at a time, until there was almost nothing left.

"The ledger," she said suddenly. "You've been keeping the ledger this whole time."

Mr. Cog inclined his head. "I met your grandmother when she opened the shop. I was seventeen. I had failed my A-levels rather spectacularly and was working in a bookshop three doors down. She asked if I knew how to keep records. I said yes, though I did not, particularly. She hired me anyway." He paused, and something flickered across his face — grief, perhaps, or the memory of it. "I have been keeping the ledger ever since."

"Show me," Marguerite said.

Mr. Cog rose without a word and retrieved the ledger from its place behind the counter. It was heavier than Marguerite remembered. He set it on the table between them and opened it to the first page.

The handwriting was Grandmother's — young, confident, not yet cramped by age or uncertainty. The first entry was dated 3 March 1976.

Mrs. Pemberton's lost letters. Found and returned. Cost: certainty about whether I take sugar. I believe I do. Two sugars. Or one.

Marguerite read the next entry. And the next. The pages turned, and the years accumulated, and the costs grew larger.

Mr. Dalton's wedding ring. Returned to correct finger (long story). 12 June 1981. Cost: certainty about whether I was ever in love. I think I was. But I cannot be entirely sure.

Young Timothy Voss, age 6. Nightmares removed. 2 September 1989. Cost: certainty about whether I am a good person. The jury, as they say, is out.

Promise repaired: Mr. and Mrs. Hough's marriage vows. 19 November 1995. Cost: certainty about my own name. Eudora. I checked my birth certificate. It says Eudora. So that is settled, at least for now.

The handwriting grew shakier as the years passed. By the time Marguerite reached the entries from the early 2000s, Grandmother's script had become so cramped and furious that it was difficult to read, as though she had been writing very quickly, trying to capture thoughts before they slipped away entirely.

Repair attempted: the Gripe marriage. Failed. He wanted me to bring her back. I told him the cost was too high. He said no cost was too high. I said that was exactly the problem. He left. I do not think he believed me. 14 April 2008. No cost incurred — I refused the repair.

Marguerite looked up sharply. "Gripe came here before?"

"Yes," Mr. Cog said. "He has been searching for someone who could undo his wife's death for a very long time. Your grandmother was not the first person he asked. But she was the first who could have done it — and did not."

"Because of the cost."

"Because of the cost," Mr. Cog agreed. "And because your grandmother understood something that Mr. Gripe, in his grief, could not. She understood that some things, once broken, are meant to stay broken. Not because they cannot be fixed, but because fixing them—" He stopped, searching for the right words. "Because fixing them would break something else. Something more important."

Marguerite turned the page.

The final entries were dated in late 2014 and early 2015. The handwriting was barely legible.

Cannot remember if I locked the door. Cannot remember if I ate breakfast. Cannot remember the name of the girl who delivers the post. I know her. I know I know her. But I cannot be certain.

Mr. Cog says I should stop. He is probably right. He is often right. I think he is often right. I am not certain.

And then, at the bottom of the page, dated 4 February 2015, the entry that Pip had read aloud weeks ago in this very room:

Marguerite Tinker, age 0. Repair requested: future. Cost: all remaining certainty. Performed by: E.C.

Marguerite's hands were shaking now, too. She gripped the edge of the ledger as though it were the only solid thing in the room.

"Tell me," she said. Her voice sounded very far away. "Tell me what happened."

Mr. Cog folded his hands in his lap. When he spoke, his voice was quiet and precise, the way it always was when he was holding something together by sheer force of will.

"Your grandmother had a daughter," he said. "Your mother. They were not close — your mother thought the shop was nonsense, thought Eudora was wasting her life fixing other people's problems when she could not fix her own. They had not spoken in years when your mother rang to say she was in hospital. You had been born two months premature. The doctors said you would not survive the night."

Something was tightening in Marguerite's throat, and she did not trust it.

"Your grandmother came to the hospital," Mr. Cog continued. "She sat beside your incubator for three hours. I do not know what she did, exactly. I was not there. But when she returned to the shop the next morning, she could not remember her own name. She stood in the doorway and asked me who I was. She asked me where she was. She asked me—" His voice cracked, just once, on a single syllable. "She asked me if she had children."

"But I lived," Marguerite whispered.

"You lived," Mr. Cog said. "The doctors called it a miracle. Your mother called it luck. Your grandmother—" He paused. "Your grandmother spent the next twelve years in a care home in Enfield, unable to remember who she was, unable to find her way to the granddaughter she had saved. I visited her every week. She did not know me. But every week, I read her the ledger. I thought—" His hands tightened in his lap. "I thought she should know what she had done. Even if she could not remember doing it."

The room was very still.

"She died last November," Mr. Cog said. "In her sleep. Peacefully, they said, though I do not know how one measures such things."

Marguerite could not speak. Could not move. Could only sit with the weight of it, the terrible, unbearable weight of knowing that she was alive because her grandmother had given away everything — her name, her certainty, her very self — to repair a future that had not yet existed.

"There's more," Mr. Cog said quietly.

"How," Marguerite managed, "could there possibly be more?"

Mr. Cog rose and crossed to the far corner of the back room, where a small wooden chest sat on a shelf beside the cracked Courage Thermometer. He opened the chest, reached inside, and withdrew a single piece of paper. It was yellowed at the edges and covered in handwriting so shaky it was almost illegible.

He set it on the table in front of Marguerite.

The handwriting was Grandmother's. The date was 16 November, twelve years after the final ledger entry. Someone — a nurse, perhaps, or Mr. Cog himself — must have brought her a pen and paper in the care home. The message was two words long.

Worth it.

---

Marguerite did not cry. She had been raised — though she had not known it at the time — by a woman who had given away her own certainty so that Marguerite could be certain of living, and although that woman was dead, and although Marguerite had never truly known her, old debts ran deep.

She sat very still and looked at the two words written in her grandmother's shaking hand, and she understood, for the first time, what inheritance really meant.

It was not the shop. It was not the gadgets or the ledger or the shelves of broken things waiting to be repaired. It was the choice. The same choice her grandmother had made fifty years ago, and every day after, until there was nothing left to give.

The choice to fix what was broken, even when the cost was yourself.

"There's something else you need to know," Mr. Cog said, and this time his voice was so quiet that Marguerite had to lean forward to hear it. "The Time-Wound Eraser. It exists."

Marguerite's head snapped up. "What?"

"It exists," Mr. Cog repeated. "Your grandmother built it twenty years ago. She never used it. It is in the locked drawer beneath the counter. She left instructions that it was not to be opened unless—" He stopped.

"Unless what?"

"Unless you asked for it."

The room seemed to tilt slightly. Marguerite gripped the edge of the table.

"She could have used it," Mr. Cog said. "At any point in those twelve years, she could have used it to undo her own sacrifice. To erase the wound of losing herself. The Time-Wound Eraser undoes one wound that time created — a death, a loss, a departure. She could have erased the night she repaired your future. She could have had her certainty back. Her name. Her life."

"But she didn't," Marguerite said.

"No," Mr. Cog said. "She did not."

Because she chose you, Marguerite thought, and the thought was so large and so terrible and so full of love that she could not hold it and look at it at the same time.

Mr. Cog rose and began clearing the tea things. He moved slowly, methodically, as though the simple act of washing up was the only thing keeping the world in its proper shape.

Marguerite sat at the table and stared at the two words written in her grandmother's hand.

Worth it.

"What do I do now?" she asked.

Mr. Cog did not answer immediately. He dried the chipped cup with a tea towel that had seen better days, set it on the counter, and regarded her with the quiet, steady gaze of someone who had spent fifty years watching people make impossible choices.

"Now," he said, "you decide what sort of Tinker you are going to be."

He filled the kettle again. Outside, the city rumbled on, indifferent and enormous. Inside, the shop waited, full of broken things and impossible repairs and the ghost of a woman who had given away her name so that her granddaughter could have a future.

Marguerite picked up the piece of paper, folded it carefully, and placed it in her pocket.

She did not yet know what she would do. But she knew, with a certainty that felt like a small, bright flame in the centre of her chest, that whatever she chose, it would cost her something.

Everything did.
