'Sherlock' video: Holmes as Watson's best man in 'The Sign of Three'Add to Favorites | Sherlock
What kind of a best man is Sherlock Holmes? That question will be answered in the second episode of "Sherlock" Season 3, "The Sign of Three." A video clip from the episode indicates that the results of this social experiment could be amusing.
If nothing else, there's a brain.
The central event in "The Sign of Three" is John Watson's ( Martin Freeman) wedding to Mary Morstan ( Amanda Abbington). As other characters realize right at the beginning of the clip, Watson is certain to ask Holmes ( Benedict Cumberbatch) to be his best man.
But that means a speech. There are also a whole lot of other wedding traditions that Sherlock will have to face in this oddest of mysteries. Also, because this is "Sherlock," we can expect the detective to solve a murder or two before the reception is over.
"The Sign of Three" airs Sunday, Jan. 26 on PBS.
