""...not for the feint-hearted, but you will enjoy one heck of a dark rollercoaster. ""
When bodies start washing up along the banks of the River Thames, DI Henley fears it is the work of Peter Olivier, the notorious Jigsaw Killer. But it can't be him; Olivier is already behind bars, and Henley was the one who put him there.
She'd hoped she'd never have to see his face again, but Henley knows Olivier might be the best chance they have at stopping the copycat killer. But when Olivier learns of the new murders, helping Henley is the last thing on his mind.
Now all bets are off, and the race is on to catch the killer before the body count rises. But who will get there first – Henley, or the Jigsaw Killer?
