A London detective makes a gruesome discovery that could solve the riddle of his son's disappearance in this crime thriller series debut.

Det. Sgt. Jonah Colley of the Metropolitan firearms unit has been wracked with guilt for the past ten years, ever since his son went missing under his care. The tragedy broke up his marriage and left him estranged from his best friend, Det. Sgt. Gavin McKinney. But now Gavin calls him out of the blue. Desperate for help, he needs Jonah to meet him at Slaughter Quay.

Jonah arrives to a horrifying crime scene where Gavin was brutally attacked and left for dead. As the only survivor, he is also a person of interest. But even while under suspicion himself, Jonah is determined to find out what happened. Uncovering a network of secrets and lies about the people he thought he knew, he's forced to question what really happened all those years ago.

The Lost is the first book in the Jonah Colley thrillers by the award-winning, Sunday Times-bestselling author of the David Hunter series.
