Manhunt

Detective Chief Inspector Colin Sutton of the Metropolitan police takes on the role of senior investigating officer, when French student Amelie Delegrange's body is discovered on Twickenham Green in 2004.

The team tries to identify a white van seen close to the crime scene of an attack, a task that proves to be difficult with 25,000 possible vans to check.

Bellfield's home is raided by DCI Sutton's relentless team as they hope to finally make an arrest, but they still can't find the suspects.
