The fourth series of 'Ripper Street' will come to Amazon Prime Instant Video in January, Amazon has announced.
The show is set in Victorian London, and again stars Matthew Macfayden and Jerome Flynn as detectives on the hunt for a killer.
Series four takes place at the time of Queen Victoria's Diamond Jubilee and sees appearances from a host of new faces, including David Threlfall ('Shameless') and Matthew Lewis ('Harry Potter').
"'Ripper Street' has a tremendously loyal fan base and is nothing short of a British institution," said Jay Marine, vice president of Amazon Video EU. "We're delighted to be launching the new series exclusively for Prime members in the UK.
"[Screenwriter] Richard Warlow has crafted another dramatic, thrilling and unmissable series to take Reid, Drake and Jackson even further on their journey through the depths of Victorian crime.
"We can't wait to kick off the New Year with another great series, and we know fans will be hooked from the first minute."
'Ripper Street' started life on the BBC, but was cancelled after two series. Amazon resurrected it and commissioned a third series, which was eventually shown on the BBC.
There's no word on whether series four will make its way to the Beeb.
The first episode will be feature-length, and will be available from January 15th. Amazon will air subsequent episodes one a week, every Friday.
