A sunburned Det. Supt Andy Dalziel returns from his holiday in Australia and finds himself immediately investigating a murder. The dead man is Declan Roach, a researcher at the local university who was found in a university laboratory clean room. The autopsy confirms that he died from nitrogen intoxication but it is not clear at first if it was accidental or not . Roach was working under the direction of Professor Fran Cunningham, who in turn has a major contract with Aphrodite, a major cosmetics firm. She is working on a formula for a rejuvenation cream that will be nothing less than a fountain of youth and there is obviously a great deal of money at stake. Andy meanwhile is thinking of packing it in and emigrating to Australia.
