On this week's show we take a trip back to Victorian London for Netflix's YA-themed Sherlock show The Irregulars, plus a jaunt to Wales for the final series of the BBC's Keeping Faith. And then, for reasons, we also review the *fourth* series of Lottery-winner drama The Syndicate, in which a group of dog groomers strike it rich. Plus we get very excited about the penultimate episode of Unforgotten (spoilers are clearly signposted but occur between 5:20 and 11:21), and explore some of the great shows that began their lives on the big screen.
