Harold Shipman: Doctor Death

On the 20th anniversary of the arrest of Britain’s most prolific serial killer, this new documentary investigates how Dr Harold Shipman got away with secretly poisoning and murdering more than 250 of his patients across three decades.

Speaking for the first time, former detectives from Greater Manchester Police who were at the heart of Britain’s biggest-ever murder investigation give their vivid insights into a case which shocked the nation.

Shipman, a well respected family doctor from the small town of Hyde near Manchester, was initially arrested in 1998 for the murder of one of his patients, 81-year-old Kathleen Grundy. Soon, however, detectives were widening their investigation as more suspicious deaths came to light. ■
