'So clever, and has the perfect twist' GILLIAN McALLISTER
'An ingenious puzzle of a novel that crackles with energy and menace' NICCI FRENCH
What if the only way to prevent a murder is by confessing to it?
Jemma Stelling has confessed to a crime - one she can't have committed. She has an unshakeable alibi: when Marianne Upton was stabbed to death outside her home, Jemma was at the police station confessing to a deadly obsession with Marianne and a plan to kill her in precisely the way she was killed.
So is Jemma innocent? Or is she an ingenious, cold-blooded murderer?
