"Death in Paradise" returns with a fantastic fourth series which sees DI Humphrey Goodman (Kris Marshall) and his team solving ever more mysterious and impossible murders. Having now settled into life on the idyllic sun-drenched island of Saint Marie, bumbling detective Humphrey Goodman continues to both frustrate and impress his colleagues with his inimitable style of investigation. From a ghostly stabbing during a seance to the confounding drowning of a bride-to-be at her hen party, Humphrey's brilliant puzzle-solving mind is pushed to the limits as he is called upon to crack a whole host of cases. He may be as forgetful, accident-prone and clumsy as ever, but his instinct for working out who the killer is hasn't diminished. And in this fourth series the murderous puzzles Humphrey has to solve are more mystifyingly challenging than ever before.
