The true crime series returns with the case of pharmacist Mitesh Patel. In 2018 he called police to tell them he had returned home to find his wife, Jessica, murdered. However, it was all a lie. Within weeks, Mitesh's double life as a gay man had become apparent to the police. Far from being a committed husband and pillar of the Hindu community, he had been plotting an affair with his lover in Australia.

Carol Taggart, a 54-year-old mother of three, appears to have been murdered by her own son in Scotland.
