William McIlvanney changed the face of crime fiction with DI Laidlaw. He wrote three Laidlaw books but left one manuscript tantalisingly unfinished. One young fan, Ian Rankin, took Laidlaw as inspiration for his own detective, John Rebus. Now, Rankin is back to finish what McIlvanney started. The Dark Remains, the story of Laidlaw's first case, is written by William McIlvanney and Ian Rankin. Set in Glasgow and featuring an original gritty detective.
