The final series of the Victorian crime drama (already available on Amazon Prime Video) begins with a less jaunty than usual title sequence – Drake is in his grave, after all, while Reid, Jackson and Caitlin/Long Susan are on the run.

With Reid (Matthew Macfadyen) in a daze after watching his friend Bennet die, Jackson (Adam Rothenberg) takes charge, and the American’s questionable past comes in useful in more ways than one.

But Reid has ‘police’ stamped through him like a stick of rock and he’s soon back on his feet – although you might find his and Jackson’s idea of being discreet (the walls of Whitechapel are thick with their ‘Wanted’ posters) laughable.
