Rea Carlisle has inherited a house from an uncle she never knew, but as she clears out the dead man's possessions, she finds a leather-bound catalog of his victims. Her father is a Northern Irish politician who wants to avoid scandal, so Rea turns to disgraced police inspector Jack Lennon. In this fourth book in the series (after Stolen Souls), though, Lennon is himself the lead suspect in a murder investigation led by one of the force's toughest cops, DCI Serena Flanagan. The timing is suspicious, and Lennon needs to find out if they are all victims of a grisly conspiracy.
