Veteran rock band the Flowers of Progress are on the island to record a new album after years of being apart, and with a major sponsorship deal hanging in the balance, tensions are running high.
However, their reunion proves to be short-lived when lead singer Stevie Smith is electrocuted in the swimming pool. It seems the victim had a stormy relationship with his brother and fellow band member Jim, while there are rifts between the others and more than one has an axe to grind.
But how could any of them have done the deed when they were all in the studio at the time? To add to Humphrey's problems, he is still finding his feet without Camille, although the arrival of new officer JP helps lighten Dwayne's workload.
