The death of Fay Partridge, a young widow who ran the very select Throstlecombe Holiday Camp on the north coast of Devon, presented the police with a singular problem. Her death posed the question, first of all, of how rather than who... For Mrs Partridge died very suddenly of a liver complaint most unlikely in a woman of her age. And her two poodles, whom she had taken to the vet on the day of her death, expired the same day from the same cause. Toxic necrosis was the verdict on each, but neither the doctor who conducted the post-mortem on Mrs Partridge, nor the veterinary surgeon who examined the poodles, could find any trace of poison to account for the condition. For Detective Chief Inspector George Masters and his team, the assignment was something of a relaxation.
