Hawaiian Hangover

Agnes and Eleanor have won a lottery and fly to Hawaii for the trip of a lifetime. Agnes has planned plenty of activities, including a snorkelling outing, though she mostly means to bask on the beach. The outing takes a grim turn when she spots a body floating in the water, still wearing scuba gear. The grieving honeymooners who arrive soon after insist the dead man was their guide. Now the two friends find themselves working alongside the local police, and their holiday becomes an oceanic investigation as they search for a killer.
