Watson: “Me, Sherlock. In court. On Tuesday. They're giving me an ASBO.”Tonight's episode was a loose adaptation of Sir Arthur Conan Doyle's 'The Dancing Men'—and when I say 'loose' I mean pants falling down, baring your arse loose. If Steven Moffat hadn't mentioned it on Twitter, I probably wouldn't have noticed. The only similarity I picked up on was that both stories have a secret code as their central theme. In 'The Dancing Men' it was a code based upon a system of hand-drawn stick men, in 'The Blind Banker' it was a system of graffiti style Hangzhou numerals. Apart from that, and a couple of possible references to 'The Sign of Four' and 'The Valley of Fear,' I caught nothing.
