Synopsis

An infamous drug baron is tortured before being coldly executed in his London home. The body of a drug dealer who appears to have met a similar fate is found in the dark waters of Loch Ness.

As more bodies are found, Detective Superintendent Jock Anderson of Inverness CID fears that he is hunting a calculating serial killer; but although he is suspicious that perhaps more than one murderer is at work, there are few clues and few leads to follow until Jock is provided with some unusual assistance from a novel source.
