Fans of the television show 'Sherlock' will be very pleased with the show's latest news, the BBC recently confirmed that the popular detective series will be returning in 2015.

'Sherlock,' which stars Benedict Cumberbatch and Martin Freeman, will reprise their roles for a 4th season, as well as a new special.

The three episodes for the upcoming series will be filmed later this year, and the special is set to go into production in January 2015, BBC One announced.

"A special, plus a new series of three episodes-it's a record-breaking run! Of course, it's far too early to say what's coming, but we're reasonably confident that the very next thing to happen to Sherlock and John, is the very last thing you'd expect," co-creator Steven Moffat said in a statement.

But can this series repeat the success of season 3? When PBS aired the premiere of last season on Jan 19th, it garnered their highest-ever rating figures, which was viewed by an average of 4 million people.

"Series Four! At last ! It's always special to return to Sherlock but this time it's even more special as we're doing... a special! Not only THAT, we'll then be shooting three more episodes which will take Sherlock and John Watson into deeper and darker water than ever before," co-creator Mark Gatiss said in a statement. "The whole Sherlock team are terrifically excited to return for four new adventures. The Game is on-again!"

"It's taken a little while to get the dates sorted as none of the boys are exactly sitting back twiddling their thumbs but there was unanimous goodwill to make this work, so we're thrilled that 221b is going to be inhabited again," executive producer Sue Vertue said in a statement.
