James Mallard signed a confession admitting that he had stolen a car belonging to his doctor with whom he and his family have long been unhappy. He had hinted to the doctor just before the incident that he would do him some harm. Mallard has now retracted his confession and asserts his innocence. He argues that he was forced into a confession by Sergeant Attrass who has long victimised him because of his criminal past. The prosecution argue that the initial confession was absolutely correct. They have eye-witness testimony linking Mallard to the crime and insist the Sergeant has treated Mallard quite fairly.
