At a party given on his boat by former rock drummer Boy Buckley, Rupert Galliers and his wife Emerald fall overboard and Rupert is pronounced dead whilst Emerald is in a coma. Jim learns that Galliers was heavily in debt, had caused a company to go bankrupt, imported cocaine and was unfaithful. This leads to the conclusion that one of the party-goers had cause to murder him. Jim must find out which one.
