When two boys find the body of teenager Florence Henderson hanging from a tree in a wood, they post a photo of her suspended body to Facebook - alerting police and family.
Meanwhile, the annual Performance Review is keeping Craven (Maxine Peake) and her team, Watende Robinson (Michael Obiora) and Terry Bird (David Crellin), on their best behaviour - the last thing they need is a case which becomes high profile before they even get to the scene.
The apparent lynching-style of the crime alarms the police. Lance Darcy, a local amateur horror film maker, is questioned alongside Florence's school mates and her distant father, Mark Henderson.
Each day thoughout this series, additional scenes are carried on into films available on BBC iPlayer and the Radio 4 website. Today, we delve into the lives of the boys who discover Florence's corpse.
