April 1889 – six months since the last Jack the Ripper killing, East London is emerging into a fragile peace, hopeful that this killer’s reign of terror might at last have run its course. Nowhere is this truer than in the corridors of H Division, the police precinct charged with keeping order in the chaos of Whitechapel. Its men hunted this maniac; and failed to find him. Starring Matthew Macfadyen, Jerome Flynn and Adam Rothenberg.
