Series 3, "The Sign of Three" In his introduction to "The Sign of Four," in a recent republication of Sir Arthur Conan Doyle's works, Martin Freeman writes about his first thoughts on auditioning for a modern-day version of the Sherlock Holmes stories: "What would 'modern' mean, in TV terms? Deductions being rapped? Holmes and Watson bombing around London in a Lexus on their way to meet with Lestrade, a wheelchair-bound lesbian with a penchant for Class-As at lunchtime?" Unfortunately, we have no rapped deductions (yet), but we do have what is definitely a first for the Sherlock Holmes canon: a dubstep version of Sherlock Holmes' theme tune. The dubstep version is, by far, the theme tune's best remix, which is the first twenty seconds of "Stag Night"; like "How It Was Done," it's pure, unadulterated fun, one of those songs you can discretely (or perhaps not so discretely) rock out to. It then transitions into the tune that accompanies Sherlock and John on their drunken excursion to investigate the flat of the Mayfly Man, where the music is as distorted as their blurred vision and alcohol-addled minds. I don't know what Arnold and Price will have in store for us in Series 4, but "Stag Night" will be hard to beat for pure entertainment!
