Stephen King has called Pelecanos 'perhaps the greatest living American crime writer', and one of the reasons for this praise may be the total verisimilitude of his writing: this is crime fiction that makes most entries in the fields seem glossy and insubstantial. The plot here involves unsolved crimes and a killer who has never been brought to justice. In 1985, a ruthless individual was kidnapping teenagers, killing them and dumping their mutilated bodies in public parks. 20 years have passed, and detectives Gus Ramone and Dan Holiday -- who worked on the original case -- have taken different career trajectories: Gus has made Detective Sergeant, while Dan has lost his job over a series of irregularities. But then a boy is found murdered in a public park, and both men find themselves seeking closure on a dark case from their pasts. All the things that distinguish Pelecanos' best writing -- flinty characterisation, solid plotting and a marked social concern -- are present here. If you haven't already, it's time to join the legions of Pelecanos admirers. --Barry Forshaw.
