The Last Temptation by Val McDermid (Tony Hill & Carol Jordan #3) (Paperback)

Facing the aftermath of her breakup with criminal profiler Dr. Tony Hill, Chief Inspector Carol Jordan immerses herself in a high-stakes undercover operation to track down a European drug trafficker and earn his trust. However, she is not the only one being monitored; a serial killer with a psychosexual obsession rooted in the darkest annals of history is also keeping tabs on her.

Meanwhile, in quiet solitude, Tony Hill is coming to terms with the scars of his past, but he’s pulled back into the field when an irresistible case presents itself. An evil force is creeping dangerously close to home, casting a chilling shadow over the life of his long-time colleague and occasional lover.

As the threat draws nearer and Tony and Carol find themselves intersecting on the treacherous path through the shattered psyche of a disturbed individual, they realise they can rely only on each other. Fear creeps in as they begin to suspect that there may be no haven left while a deranged killer inches closer to realising his most twisted fantasies.
