This polished mystery seems more the work of a seasoned genre master than the first novel it is. Det. Supt. Duncan Kincaid, spending his vacation from Scotland Yard at a Yorkshire time-share along with several other guests, finds his holiday anything but relaxing. Immediately after he arrives at the elegant estate, he overhears a heated argument between the snobbish caretaker and her sarcastic assistant manager. Late that evening, the assistant is electrocuted in the Jacuzzi. To the consternation of Yorkshire police, Kincaid assumes an active role in the investigation, which becomes more urgent after two more deaths.

A week's holiday in a luxurious Yorkshire time-share is just what Scotland Yard's Superintendent Duncan Kincaid needs. But the discovery of a body floating in the whirlpool bath ends Kincaid's vacation before it's begun. One of his new acquaintances at Followdale House is dead; another is a killer. Despite a distinct lack of cooperation from the local constabulary, Kincaid's keen sense of duty won't allow him to ignore the heinous crime, impelling him to send for his enthusiastic young assistant, Sergeant Gemma James. But the stakes are raised dramatically when a second murder occurs, and Kincaid and James find themselves in a determined hunt for a fiendish felon who enjoys homicide a bit too much.
