Sherlock Holmes can tell a software designer by his tie and an airline pilot by his thumb. He has a unique analytical brain and, unlike anyone else in the world, he staves off boredom by solving crimes. When a chance encounter brings soldier John Watson into Sherlock's life, it's apparent the two men couldn't be more different, but Sherlock's intellect coupled with John's pragmatism soon forge an unbreakable alliance.
In season three, Sherlock returns but will things ever be the same again?
