/sherlock-special-2015-photo-benedict-cumberbatch-martin-freeman/Way back in November, we got our first official look at Sherlock Holmes (Benedict Cumberbatch) and Watson (Martin Freeman) for this year's Sherlock Special. Now, shooting on this episode has finally begun, with both actors spotted on set. Production is taking place in London, and as you can see in the photos below, it appears our heroes are out of time.

The /tv/sherlock/Sherlock Christmas Special was written by series creators Mark Gatiss and Steven Moffat. It is expected to air this December, just in time for the holidays, and it is coming in place of a full season. About the show, Martin Freeman said earlier this year:

"Steven and Mark have had a great idea what they can do next, and it is an exciting, mouth watering idea..."

A fourth season of Sherlock is expected to begin shooting this year as well. Though, no specific details or plans have been confirmed at this time. In the meantime, take a look at these images below and see if you can figure out what is possibly going on. While we won't hear about the plot until closer to the air date, there is sure to be plenty of fan speculation before then:
