Watch Whitechapel Season 3 in Australia

The new series of the police drama set in London's East End begins with the first of a two-part story. The team investigate the gruesome murder of four people in a seemingly impregnable tailor's workshop. The crime sends shockwaves throughout the area - what can Chandler and Miles learn from history that could help them to solve these particularly grizzly killings?

A second mass murder occurs with no signs of an obvious break-in and no forensic evidence for Chandler and the team to use. The crimes begin to take on an almost supernatural edge and local residents wonder how they can sleep soundly in their beds when doors and locks offer no protection from whoever is responsible.

As Chandler and Miles attend the christening of Miles's daughter, a fox runs through the streets of Whitechapel with a human arm in its mouth. Later, more body parts from the same victim are washed up by the Thames, all containing evidence of a fatal poisoning. The only clue to the identity of the victim is a tattoo on the headless torso - can the team crack this gruesome case before the killer strikes again?

The police drama series set in the East End continues with the second of a two-part story. When traces of the aphrodisiac Spanish fly are found in murder victims, Chandler and Miles question what kind of killer they could be up against. The team are taken to the heart of a dark obsession where romance and love take on a sinister turn.

When a babysitter is murdered and a dangerous patient and former Whitechapel resident escapes from a psychiatric unit, the area is hit by a series of terrifying events. Fearing that a spree killer is on the loose, Chandler, Miles and the team must act fast to prevent more deaths. Meanwhile, Chandler's quest to bring in a suspect alive jeopardises his relationship with Miles.

The drama series concludes with the second in a two-part story. With the body count rising, Miles and Chandler clash over the direction of the investigation. Having already survived the killer's wrath once, Morgan Lamb is of particular interest to the team - especially Chandler. As the chase escalates, will the detectives be able to put their differences aside in the face of their toughest adversary yet?
