The Lost is the beginning of a new crime series, and introduces readers to Jonah Colley, an armed response officer with the Met. Ten years ago, the abduction of Colley's young son ended his career as a police detective and almost destroyed him. A plea for help from an estranged friend leads Jonah to a scene of carnage, and a brutal attack from which he's the only survivor. Discharged from the force and under suspicion himself, his search for the truth throws doubt on everything he thought he knew - and forces him to question what really happened all those years ago.
