For Inspector Michael Angel, the savage murder in a hospital of the criminally insane 20 years ago marks the beginning of this gruesome trail of enquiries to find a missing nurse. In spite of obstruction from the Chief Constable, this quirky Yorkshire policeman with only his two pet cats for consolation reduces the suspects to one, by resorting to an unusual and original strategy. A dead woman wearing one stocking inside out, an American class ring, a missing videotape of the lovely Lola, and two dead cats all play their part in this scramble to find the killer in this unusual and chilling mystery.
