The key was in the right-hand pocket of the winter coat she was taking to the dry cleaner's. She found it when she was checking for tissues — he always left tissues in his pockets, had done since she'd known him, and she had stopped mentioning it the year they moved in together because the complaint had become part of knowing him rather than an inconvenience. She didn't find any tissues. She found a key on a ring with no other keys, which was strange, because you don't carry a single key on a ring unless you want it to be easy to remove.
She set it on the kitchen counter and finished gathering the coat. At the dry cleaner's, the woman asked if she'd checked all the pockets and she said yes. On the way home she stopped for coffee she didn't drink, sitting in the window of the caf— on the corner and looking at the street.
When she got back the key was where she'd left it. She picked it up and held it for a moment — a standard door key, nothing distinctive, nothing written on the ring — and then put it in her own pocket and went to make dinner.
Marcus came home at seven-thirty, which was his usual time. He kissed her, asked about her day, opened a bottle of wine, and they ate together at the kitchen table. He was in a good mood. He had been in a good mood for three weeks, which she had noticed and attributed to a project at work that was apparently going well.
She said nothing about the key.
She didn't know yet what she was doing with the information. She only knew that she was not ready to give it back.
It was not difficult to find. London is a city of rental records, and Marcus's name, which was the only name she knew to search, appeared on a lease that had been filed with the council two years and four months ago. The flat was in Hackney. Sixteen minutes on the Overground from the station where he changed lines on his way home from work.
She found this out on a Thursday morning, alone in the flat, using her laptop while he was at the office. She sat with the information for a long time. Two years and four months. They had been together for six years and living together for four. The lease predated the last holiday they'd taken together. It predated the trip to her parents' for Christmas last year, and the one before. It predated the night he had, unprompted, said I can't imagine my life without you in it, which she had written in her journal because she thought it was the kind of thing you wrote down.
She closed the laptop and washed up the breakfast things.
On a Saturday when Marcus was supposedly at a friend's football match, she took the Overground to Hackney. She found the building on a residential street that was quieter than the main road, with a small park opposite and a dry cleaner's on the corner, which she noticed with something like a laugh that didn't quite arrive.
The key opened the main door and the door on the second floor at the end of the corridor. She did not let herself in right away. She stood in the corridor for a moment, listening. There was no sound from inside. She went in.
The flat was clean and ordered and clearly used. Not lived in — there was no mess, no evidence of daily accumulation — but used regularly, the way you use a room you return to. The kitchen had mugs and a French press and coffee, the good kind. There were two pillows on the bed with different pillowcases. The windowsill had three plants that were all still alive, which meant someone was watering them.
She stood in the middle of the living room for a while, trying to understand what she felt. Rage was available; she could sense it at the edges. But what was actually present was something quieter: a comprehensive alteration of her knowledge of the past six years, re-filing itself without being asked.
On the bookshelf there were books she had given him that she had assumed he kept somewhere else, having misplaced them, him having said I think they're in a box from the move. There was a photograph of Marcus and a woman at what looked like a wedding. They were both laughing at something outside the frame. He looked the way he looked in photographs where nobody had told him to smile.
There was a drawer in the kitchen. She opened it and found an envelope with his name on it and inside it a bank statement with a balance she had not known about. Not a remarkable amount — just enough to understand that there had been, for years, money she hadn't been told about. The accounting of a person who had imagined, and then prepared for, a division.
She took a photograph of the bank statement with her phone. She returned the statement to the envelope. She put the envelope back in the drawer. She straightened the corner of the drawer mat where her hand had disturbed it.
She left the flat, locked both doors behind her, and walked back to the Overground. On the train she looked at the photograph on her phone and thought: he has been building an exit for two years. And then, correcting herself: he has been building an exit. Two years is only what I can prove.
Marcus came home that evening at six, which was early for a football day. He said the match had been rained off. He brought beer and a bag of crisps and seemed genuinely pleased about this — pleased to be home, pleased to see her, in the slightly-too-warm way that she now understood was the specific mood of a person who has recently been somewhere they should not have been.
She had been thinking, while she waited, about the shape of the decision. Not whether to leave — that was already resolved, the way some things resolve quietly and ahead of the moment you might have expected. But when, and how, and what she wanted to have arranged before the arrangement became visible.
He opened a beer and offered her one and she said yes. They watched television and she laughed at the same things she always laughed at and he fell asleep on the sofa before eleven, as he often did. She watched him sleep for a moment, which she had done thousands of times, in this flat and in the flat before this one and in the small room at the back of a shared house where they had first slept together.
He was the same person he had always been. That was the part she kept returning to. She had not made an error of judgment about his character. He had not changed. He had simply been this person, always, and she had not had access to all of him at once.
She went to bed and slept well, which surprised her slightly, and put the key back in his coat pocket in the morning before he was up. She smoothed the pocket out. She put the coat back on the hook.
She had two weeks. She had already started.
