Death in Paradise: Erupting in Murder

A scientist studying a live volcano is found dead halfway up the mountain, and the evidence points to a heart attack. Humphrey is convinced one of the dead man's colleagues murdered him - an unlikely possibility, since they all have alibis. Away from the investigation, the inspector eagerly awaits Martha's return to the island, while JP settles into married life and Dwayne makes an error of judgment while talking to a journalist. Kris Marshall, Josephine Jobert and Danny John-Jules star in the sun-soaked whodunit, with guest appearances from Douglas Hodge, Natasha Little and Sally Bretton
