The much awaited "Sherlock" Season 3 scheduled air date is around the corner, January 1, 2014. There are enough spoilers and official synopses now to guess 'almost' correctly what is going to happen in the new instalment of BBC's "Sherlock."

In an interview with Wales Online, Benedict Cumberbatch, who plays Sherlock, said that in the upcoming Season 3 of "Sherlock," there is a "fantastic trajectory in Sherlock's character arc." The actor indicated that his character will return after two years to find that he is not "really fitting in."

From the position of not "really fitting in," Sherlock will move to "doing incredibly well," according to Cumberbatch. He will form a "bond again with John." However at first, Sherlock will get it "so wrong, so so wrong."

Talking about the upcoming three episodes, Cumberbatch said: "They have some extraordinary adventures in the first and second episodes and then in the third they are challenged by a situation and a master villain who brings him to his knees. What's exciting about this series is we see Sherlock in real peril."

The new villain, Charles Augustus Magnussen, is expected to appear in the third episode, "His Last Vow," of "Sherlock" Season 3. An official synopsis released by BBC describes the new antagonist as the "Napoleon of Blackmail." Cumberbatch said that the new antagonist is not a "mad chaotic villain" unlike Prof. Moriarty.

"He will chime with people who know what a bully is - he is the archetypal bully and his means and methods are chillingly everyday in our culture. He's a smart creation, very real and not fantastical." Cumberbatch said. "He's got a foreign perspective on the English culture which Holmes so perfectly personifies and the fact that he fights on the side on the angels. He sort of reduces what Holmes protects."

The premiere episode, "The Empty Hearse," will pick up two years after Sherlock's fake death. The most loved fictional detective will return to stop a terror attack on London's underground rail system. As a prequel of the upcoming season, a mini-episode of "Sherlock," called "Many Happy Returns," is scheduled to air on Christmas Day on BBC. This bonus episode will show the time-jump and reveal that someone is not convinced that Sherlock is dead.
