Making the seemingly-endless wait for new “Sherlock” episodes a tad bit more bearable, Masterpiece unveiled a new trailer for Season Four during 2016 San Diego Comic-Con.
Slated to go live on PBS sometime in 2017, the popular series returns with marquee stars Benedict Cumberbatch and Martin Freeman.
And according to the preview, it seems Season 4 will begin as Doctor Watson and his wife Mary prepare for their biggest challenge yet- becoming first-time parents!
