Manhunt

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 review findings to DCS Hamish Campbell and suggests a strategy called Minstead Lite, but Hamish wants Colin to stay on to see this new approach through.

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.

The team is losing morale: it's highly unlikely Minstead Man will appear again after such a close call, and the surveillance may be cut short before they can catch their culprit.
