Manhunt

After French student Amelie Delagrange's body is found on Twickenham Green in 2004, Detective Chief Inspector Colin Sutton of the Metropolitan Police is appointed as senior investigating officer, tasked with leading the investigation.

DCI Colin Sutton and his team are trying to identify the white van spotted close to the crime scene at the time of the attack from an extensive trawl of CCTV images, but there are 25,000 possible vans that need to be checked.

Detective Chief Inspector Colin Sutton briefs the team in preparation for Bellfield's arrest, but when they raid his home, they can't find him.

DCI Colin Sutton is tasked with reviewing Operation Minstead, an 11-year inquiry to catch the "Night Stalker," a notorious serial rapist active in Southeast London. Colin questions the team's focus on DNA but also realizes how inadequate their resources are for an investigation of this scale. When an attack that fits a lot of the criteria is screened out, Colin's instincts yield a new lead.

Colin presents his findings to DCS Hamish Campbell and suggests a strategy called `Minstead Lite'.

The Force Tasking Group must decide whether to fund Colin's high stakes gamble; not only is it expensive, but there's absolutely no guarantee it will work.
