A confession of murder proves problematic for DI Richard Poole and the team when a wife admits to killing her husband but the body is nowhere to be found. Can Richard solve the mystery? And could his feelings be clouding his judgment?

With Richard struck down by a tropical disease and Camille in Paris, it is left to Dwayne and Fidel to solve the apparently impossible murder of a local diver. As if their job isn't tough enough, they also have to contend with holidaying British cop DS Angela Young, who proves to be even more annoying than Richard.
