Diet for Death — Janet Laurence

Darina Lisle is accompanying her recently widowed mother for a reviving stay at the Conifers Spa health farm, hoping it will enable her to lose some of the weight gained since her honeymoon in the south of France. Weight is not the only challenge being faced by an entertaining and varied collection of guests: what is healthy eating? Is being overweight something to worry about? The spa itself, run by a friend of Darina's, is in a severe financial crisis, and there are staff troubles. Darina's husband, William, is part of the investigating team called in when death is discovered. Possible motives multiply. Darina herself is faced by personal and career challenges that force her to reassess some long held preconceptions as she tries to sort out the puzzles surrounding the murder, then finds that she is confronting an unexpectedly strong and violent killer.
