Negative Buoyancy — Valerie Goldsilk

After dumping her boorish boyfriend, Madeleine LeMesurier takes a break from her job at a Hong Kong-based detective agency and signs up for a scuba diving holiday in Thailand. Despite the presence of hunky Australian investment banker Robert Maine on the dive boat, the vacation turns out to be far from idyllic. A series of strange accidents, a missing diver, and a baffling death are simply the beginning. Just as Madeleine begins to realise that some of her fellow divers are not what they claim to be and that a strange conspiracy is unfolding around her, a gang of modern-day pirates boards the ship.
