Manhunt is the real-life story of how the 2004 murder of French national Amelie Delagrange on Twickenham Green was eventually linked to the 2003 murder of Marsha McDonnell and the 2002 abduction and murder of Milly Dowler as she traveled home from school.
Walking home following a night out with friends, 22-year-old Amelie was savagely attacked and struck several times on the back of the head with a hammer. Although relatively experienced in murder investigation, DCI Colin Sutton was assigned to the case by London's Metropolitan Police. Hard-working and instinctive, Sutton dedicated himself to finding Amelie's killer. Despite very little evidence, his painstaking approach and the diligence of his fellow officers gradually led to breakthroughs in the case.
