DI Humphrey Goodman and his team are back solving increasingly puzzling murders on the beautiful island of Saint Marie. From a body on a volcano to a two-part story which takes the team to London, the crime is not just troubling Humphrey but also causing him to question his relationship with Martha. Meanwhile, the team are concerned for Sergeant Florence Cassell when an old friend is found dead. Dwayne is forced to confront his past as he grapples with the death of his father and JP turns to Dwayne for marriage guidance. Selwyn's intervention in a case puts Catherine at the centre of the mayoral elections, while the team continue their investigations into strange deaths and unexplained events. The sixth series of the hugely popular show delivers its usual recipe of fun, emotion and intrigue - with a few surprises too - all served up in the glorious Caribbean sunshine.
