She Left Herself Behind - Harriet Crowe

Fourteen months ago, Claire Ashford's sister disappeared.

Yesterday, the police formally closed the case.

Claire is the only person still looking.

She has stopped sleeping. She has stopped living. Her kitchen table has become an archive - forty-three lines of investigation colour-coded and refined, a map of Sara's last known movements, a photograph of a man with his hand at her sister's waist that no one was willing to investigate.

And a single sentence in Sara's journal, written three weeks before she vanished: He wants to know what I know.

Claire is certain she knows what happened. She has a therapist she trusts, a support group she has come to rely on, a method she has refined into a discipline. She is close.

But something else is closing in too - something she cannot name, small wrongnesses that accumulate in her attention and refuse to go away.

And when she finally understands what it is, she will have to decide whether she still wants to find the truth.

She Left Herself Behind is a British psychological thriller for readers of Tana French, Paula Hawkins, and Sarah Waters - a story about obsession, betrayed trust, and how far one woman will go when the system gives up on her family.
