Due to the busy schedules of those involved with Sherlock (particularly stars Benedict Cumberbatch and Martin Freeman, who portray Sherlock Holmes and John Watson, respectively), it's always a long wait between seasons. This year, we'll be treated to a special one-off episode set in Victorian-era London, seperate to the previous seasons, serving as a throwback to the time period whence Sherlock Holmes creator Arthur Conan Doyle penned the original novels. This brand new image of Cumberbatch and Freeman was released ahead of Sherlock's 2015 San Diego Comic-Con panel, with the duo looking spick and span in 19th century attire. Are you excited about this more classical take on the acclaimed BBC series?
