"I think I'll surprise John. Pop into Baker Street, who knows? Jump out of a cake." "Baker Street? He isn't there anymore. It's been two years. He's got on with his life." It has been two years since Sherlock Holmes dived from the roof of St Bartholemews, coat flapping like a superhero's cape. Two whole years since Benedict Cumberbatch's eyes flashed at the sight of an intriguing murder (on-screen at least); two years, a couple of Hobbit films, a Star Trek adventure and an astronomical ascension in fame for both Cumberbatch and Martin Freeman. Both stars have been plagued by the question since 'The Reichenbach Fall': comedian Jack Whitehall was joking the about theories with Cumberbatch just a few weeks back on Graham Norton's show. Some of us haven't got on with our lives that much; the Sherlock Series 3 trailer only hit the net days ago, and yet more than a million people have watched it. It's maybe the biggest drama to come out of the BBC for a decade: no surprise they're making pride of New Year's Day, slotting it in at 9 o'clock in the evening. Here we go again; the theories will no doubt spiral across cyberspace, but how many of these theories are mad, and how many of them must be true? Let's look at the facts, eliminate what must be false, and hopefully, blow your mind with a couple of ideas that you hadn't even considered. One last time: how did Sherlock Holmes fake his own death?
