Water Rats

The Nemesis crew hear gunshots coming from inside a yacht in the dead of night. Boarding the yacht they find a bloodbath; two dead bodies and a badly injured woman who makes a garbled statement.

The detectives are called in to investigate when a young woman believed to have been stalked by an admirer called "Desperate Dave" is reported missing.

The Water Police are called to a robbery scene where a quantity of fireworks were stolen off a barge. Just as they arrive at the scene, an explosion sends the owner and his assistant flying.
