There's always something beneath the surface.
When a body crops up under strange circumstances in the town of Shawton, two local inspectors - Joel and Gina - are baffled by the case, pushing them to request the services of one vaguely notorious plonker: Anna Pendleton.
With the many tides closing in around her, the young private detective must solve the mystery of what is lurking beneath the water, and discover why everyone has been acting so strangely before the whole town succumbs to the terror from the deep.
Anna Pendleton's second adventure in the Pendleton Case series,
The Mystery of the Mutant Water Devils,
is a snappy, blood-filled horror-comedy, and a triumphant follow-up to
The Case of the Giant Carnivorous Worm.
