Ellen E Jones and Mark Kermode are on patrol, investigating why the police procedural continues to be so arresting for audiences.

Mark meets the film writer and critic Kim Newman who charts the beginnings of the genre and some of its tropes. Next, he talks to the director and documentarian Sandhya Suri, to discuss her feature film debut, Santosh, that follows the journey of a widow turned police constable.

Meanwhile, Ellen discusses how fiction aimed to mimic reality in 90s TV series, Homicide: Life on the Street, with actor from the show, Kyle Secor. She also speaks to Simon Ford, executive producer of the documentary series, 24 Hours in Police Custody, who explains how dramatic structure borrowed from fiction has helped the award-winning programme tell wider stories about the world around us.
