If you’re a “Sherlock” fiend like me, you’ve probably already been watching the episodes online (if you’re a citizen of the United States, like I am), or you have been plopping down in front of the television, eager to see what is going to happen next (if you’re in the U.K.). Either way, you are still fanning yourself over the first episode and are eagerly awaiting the next episode.

The first episode, “A Scandal in Belgravia” was simply amazing, so the anticipation level is astronomically high for the next episode, “The Hounds of Baskerville.” If you can’t wait to see what happens in the episode, BBC has put out a worldwide trailer that gives you a little look at the mystery Sherlock (Benedict Cumberbatch) and John (Martin Freeman) are going to be solving this Sunday.

The episode is a TV adaptation of “The Hound of the Baskervilles” by Sir Arthur Conan Doyle, and also stars Mark Gatiss, Rupert Graves and Una Stubbs. The episode also guest stars Russell Tovey (“Being Human”).

You can check out the video (which is awesome!) below. Make sure to write what you think about the video and the popular BBC show in the comments section below.
