'Watch out Rebus, there's a new detective in the running to become Scotland's top cop...a real cracker of a page-turner that is truly difficult to put down.' Scotland Correspondent

Your darkest moment is your most vulnerable...

Stephen Berry is about to jump off a bridge until a suicide prevention counsellor stops him. A week later, Stephen is dead. Found at the bottom of a cliff, DI Luc Callanach and DCI Ava Turner are drafted in to investigate whether he jumped or whether he was pushed...

As they dig deeper, more would-be suicides roll in: a woman found dead in a bath; a man violently electrocuted. But these are carefully curated deaths - nothing like the impulsive suicide attempts they've been made out to be.

Little do Callanach and Turner know how close their perpetrator is as, across Edinburgh, a violent and psychopathic killer gains more confidence with every life he takes...

An unstoppable crime thriller from the #1 bestseller. The perfect read for fans of Karin Slaughter and M. J. Arlidge.

What others are saying about Perfect Crime:

'Addictive, absorbing and absolutely page turning, the fifth book in the DI Callanach crime thriller series lives up to its name... I haven't read any of the previous books in this series, but that didn't matter, it reads perfectly as a standalone.' Reader review

'Perfect Crime is exciting and shocking in equal measures. Old foes return, new psychopaths are introduced, and there's a bit of personal stuff going on too. This is easily one of the best police procedural/crime series around.' Reader review

'This series of books are just fantastic. They are dark, creepy, addictive and I can't recommend them highly enough.' Reader review
