Start with Perfect Remains. 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 Edinbugh, a violent and psychopathic killer gains more confidence with every life he takes.
