In London, the police set up a new Unsolved Murders Unit to catch the criminals nobody else can. In Geneva, millionaire art collector Miles Faulkner was pronounced dead two months ago. On a luxury liner en route to New York, the battle for power within a wealthy dynasty is about to turn to murder. And at the heart of all three investigations are Detective Chief Inspector William Warwick and ex-undercover operative Ross Hogan.
An unputdownable story of murder, revenge and betrayal.
