Eleven years ago, Nora Vane met Sasha at a friend's wedding.
Last November, Sasha was found unconscious on a Surrey road.
Nora has decided to find out what happened in between.
She is good at this. She has always been good at this. A spreadsheet of cancelled plans, colour-coded by probability. A list of friends who stopped calling. A three-day-old voicemail. The shared calendar Sasha had proposed two years into the friendship - it makes sense, Sasha had said, if we're trying to coordinate, it's easier to see when the other person is free.
Seven weeks of methodical investigation. Three women who will not return Nora's calls. A doctor who tells her, carefully, to allow the investigation to continue through its own process. A message recovered from a group chat Nora did not know existed, dated four days before the end:
She's already looking and I haven't gone anywhere yet.
Nora is thorough. Nora is analytical. Nora has known Sasha for eleven years.
But a record only captures what the recorder chooses to see. And the closer Nora gets to what happened in those last weeks, the closer she gets to a question she has not allowed herself to ask.
What I Did to Her is a psychological thriller that reads twice. The first time, you follow Nora's investigation. The second time, you understand what you were willing to believe.
For readers of Liz Nugent, Tana French, Louise Doughty, and Lisa Jewell - a story about love that watches, attention that controls, and the precise moment when the reader understands what the narrator cannot.
