Based on the true story of Albert Goozee, who, on a summer's afternoon in 1956, knifed to death his 53-year-old landlady Lydia Leakey and her 14-year-old daughter Norma at a popular New Forest picnic spot. Goozee claimed to have become trapped in an adulterous affair with his middle-aged landlady, and that he had been blackmailed into returning every time he had tried to leave or break off the relationship. Goozee was tried only for the murder of the teenage girl, convicted and imprisoned for life.
