Don't miss the new, devastatingly good thriller from Helen Fields, The Institution. Coming March 2023 - available to pre-order now!

'One of the best crime fiction series out there... Helen Fields always delivers gripping, compelling, thrilling and tense stories full of intriguing characters.' Reader review,

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:

'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
