Welsh’s sizzling new novel, Crime, is a thrilling journey into the bright glamour of the Sunshine State and a seething underworld of utter darkness. Now bereft of both youth and ambition, Detective Inspector Ray Lennox is recovering from a mental breakdown induced by occupational stress and cocaine abuse, and a particularly horrifying child sex murder case back in Edinburgh. On vacation in Florida, his fiancée Trudi is only interested in planning their forthcoming wedding, and a bitter argument sees a deranged Lennox cast adrift in strip-mall Florida. In a seedy bar, Lennox meets two women, ending up at their apartment for a coke binge, which is interrupted by two menacing strangers. After the ensuing brawl, Lennox finds himself alone with Tianna, the terrified ten-year-old daughter of one of the women, and a sheet of instructions that make him responsible for her immediate safety. Lennox takes the girl to an exclusive marina on the Gulf coast, and quickly suspects that he has stumbled into a hornet’s nest: a gang or organized paedophiles, every bit as threatening as the monster that haunted him back in Edinburgh. His priority is to protect the abused girl, but can the edgy Lennox trust his own instincts? And can he negotiate her inappropriate sexuality as well as his own mental fragility? In Crime, Welsh has written a shocking and gripping story about the corruption and abuse of the human soul and the possibilities of redemption.

Justice can be a blunt instrument "Men like him usually tell the story. In business. Politics. Media. But not this I repeat, he is not writing this story." Ritchie Gulliver MP is dead. Castrated and left to bleed in an empty Leith warehouse. Vicious, racist and corrupt, many thought he had it coming. But nobody could have predicted this. After the life Gulliver has led, the suspects are corporate rivals, political opponents, the countless groups he's offended. And the vulnerable and marginalised, who bore the brunt of his cruelty - those without a voice, without a choice, without a chance. As Detective Ray Lennox unravels the truth, and the list of brutal attacks grows, he must put his personal feelings aside. But one question refuses to go away... Who are the real victims here?

"The truth is what we say the truth is . . . " Former detective Ray Lennox is determined to start a new life. He has left Edinburgh Police behind for a fresh career and a fresh relationship in Brighton. Then he meets Mathew Cardingworth. Rich, smooth-talking and immaculately dressed, he is seemingly a pillar of the local community - yet he soon draws Lennox back to a past that he's desperate to forget. As Lennox identifies the links between Cardingworth, a series of violent attacks and the disappearances of a group of foster care boys, he is forced to ask what must he sacrifice to expose the truth?
