Contrary to popular belief, the special episode won't be a shortie uploaded on video sharing website YouTube. Co-writer Mark Gatiss assured fans of a lengthy episode through this tweet!

For some reason, people seem to think the #Sherlock special will be about 7 mins long. It’s episode 10, my dears. It’ll be 90! — Mark Gatiss (@Markgatiss) July 8, 2014

Sherlock is a modern take on the classic adventures of Sherlock Holmes (played by Benedict Cumberbatch) and his trusty sidekick Dr. Watson (played by Martin Freeman). Set in the 21st century, the show follows the duo as they solve crimes in London.

Notorious for making fans wait years before returning to the small screen, Sherlock ended its third season without a set air date for it's fourth. Fans, however, were hoping for a Christmas return of their favorite TV detective.

These hopes were dashed a few months ago when Gatiss announced that it would be at least another two-year wait before the next season airs.

But no matter the length of the wait, fans will never lose faith that their beloved Sherlock Holmes and his gang will return to their screens once more.
