Sophie Hannah's unguessable thrillers have readers hooked!

'INGENIOUS! I challenge anyone to unravel this clever whodunit' 
'Sophie Hannah could well be our modern Christie, such a deliciously complicated plot. Her best yet!!' 
'This murder mystery really did blow my mind. It kept me awake at night! Absolutely brilliant' 
'This lived up to its press for me. I loved every page -- a truly impossible puzzle!!' 

What if the only way to prevent a murder is by confessing to it?

Jemma Stelling has confessed to a murder - 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 murderous 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?

Can someone be guilty of the opposite of murder?
