Fan demand meant the show was picked up by Amazon Prime and now it returns to BBC1 - who axed it after the second series
The year is 1894 and the sleazy gin joints and brothels of Whitechapel continue to be haunted by the spectre of serial killer Jack the Ripper, who is still at large.
But the impoverished residents of East London will soon have even more tragic events to endure.
The third series of Ripper Street kicks off with a devastating train wreck, which claims the lives of 55 people.
And as the search for the armed robbers who hijacked the locomotive gets underway, Det Insp Edmund Reid (Matthew Macfadyen) is reunited with his former H Division colleagues, Bennet Drake (Jerome Flynn) and Captain Jackson (Adam Rothenberg).
Drake has been promoted to Inspector with the Manchester City Police, but finds himself back in London, heroically pulling survivors from the train.
“Drake is multi-layered,” says Jerome, 52. “He’s probably the richest character I’ve played on TV.”
Ripper Street was cancelled by the BBC after the second series, only to be rescued by Amazon Prime , and this is the first time season three has been seen on terrestrial TV.
And to excite fans further, Jerome confirms, “We’re now about to start filming season four.”
