Watched the third and unfortunately final (for the season) episode of Sherlock last night. This one has the big reveal of Moriarity and boy it was a corker. Slap together chunks from Doyle's The Bruce Partington Plans and The Final Problem and overlay that with some truly diabolical plots from the world's only 'consulting criminal' Jim Moriarity (People wired with explosives and forced to read text messages over the phone to Sherlock) and you get a slam bang conclusion to the first series of Sherlock Holmes adventures in the here and now. Writer Mark Gaddis really pulled out all the stops for this one, jamming enough plot twists for any three episodes into one.
The good news is, the producers have confirmed that the series will be back for a second season. The slightly bad news is that they're not sure exactly when, given Steven Moffat's busy schedule. But anyway, Holmes and Watson will be back, and that's a good thing.
