We recently got a glimpse of what’s to come in Season 3 of Sherlock with the release of the teaser trailer. But since it will be a while before we get more episodes of the BBC series, something has to hold us over til Season 3 airs in 2014 and that’s where The Sherlock Files: The Official Companion to the Hit Television Series comes in.

The 160-page full-color trade paperback by Guy Adams, which was released last month, covers the events of Sherlock Season 1 and Season 2, and contains Dr. John Watson’s blog entries regarding cases that he and Sherlock Holmes have worked on, police reports, newspaper clippings, photos, and other case clues. Embedded throughout the book are Post-It notes left by Sherlock, and sometimes there’s rebuttables from Watson.

Along with being an actual Case Files type of book, The Sherlock Files also includes interviews with the series stars, like Benedict Cumberbatch and Martin Freeman, as well as the writers and co-creators Mark Gatiss and Steven Moffat, who all talk about the scripts, behind-the-scenes production, filming experiences, and comparisons between Sir Arthur Conan Doyle’s original stories and their televisions, as well as how previous Sherlock Holmes movies have influenced the modern-day series.

The book is packed with information and background details for the characters and episodes, so I decided to put together this list of 10 Facts About Sherlock From ‘The Sherlock Files: The Official Companion to the Hit Television Series’ to give you just a tiny taste of what The Sherlock Files has to offer.
