Donal investigates the seemingly motiveless murder of 51-year-old Penny Bell, who was found dead in her car on 6 June 1991, in Uxbridge, near London. Having been stabbed over 50 times, Bell's death appears to have been at the hands of someone she knew. Donal explores the theory that she may have been being blackmailed in the days and weeks prior to her death.
