Cruise Ship Serial Killer

Before they can even set up the office of CSCI, Cruise Ship Crime Investigators, the two agents are called to a mid ocean ship where a spree-killing has started. Too far into the Pacific to turn back, nine days before seeing Polynesia, and the killing is nightly. With the murderer at large no port will allow them to dock even if they do arrive, and the ship will be running low on fuel and food.
