The fantastic BBC series Sherlock doesn’t return to airwaves for a few more months, but thankfully a teaser trailer has been released online to offer fans a tantalizing look at the show’s third season while we wait.  The teaser trailer offers a brief glimpse of nearly all of the show’s characters, including Benedict Cumberbatch as the titular Sherlock and a mustached Martin Freeman as his trusty companion Watson.  It's admittedly not much, but when it comes to Sherlock, every morsel must be savored.  Hit the jump to watch the teaser trailer and click here to read our recap of the show’s panel from Comic-Con.  Sherlock season three will air first on the BBC in the UK, followed by its US debut on PBS in early 2014.
