Following its cancellation, then pick-up by Amazon Prime, Ripper Street has had a rocky journey – but finally after already airing on Prime, the third series of the period crime-drama returns to BBC One Friday, 31st July at 9pm.

Four years have passed. Time that has seen Reid (Matthew Macfadyen), Drake (Jerome Flynn) and Jackson (Adam Rothenberg) split and isolated from one another. But when the robbery of a goods train leads to a cataclysmic locomotive disaster on Leman Street itself, the men and their resentments are reunited to seek its cause.

Meanwhile, Long Susan (MyAnna Buring) has made good on her promise to take control of Obsidian Estates, and has turned it into a legitimate business of huge philanthropic ambition. But such aspirations have a price – one which is paid by all those to lose their lives in the Leman Street Disaster.
