Saw this on TV years ago and, while I couldn't get the images of Robson Green and Hermione Norris our of my head when I read it, the book surpasses the television portrayal. As it should. Nuanced and shocking in equal measure, Val McDermid leads the reader through the dark passages of a deranged killer's mind while making uneasy parallels with the workings of Tony Hill's damaged psyche.
A thinking person's thriller, going beyond the sensational aspects of the unfolding events to lay out the rationale behind the irrational nature of the acts.
Believable. Unsavoury and frightening, but believable.
