Masterpiece Mystery! Sherlock, Season 2
The struggle goes on in 21st-century London as the updated team of Sherlock Holmes and Dr. Watson battle the worst that modern criminality has to offer, including a computer-savvy arch-villain who wants to rule the world. Benedict Cumberbatch (War Horse, Tinker Tailor Soldier Spy) returns as the world's foremost consulting detective, with Martin Freeman (The Hobbit, "The Office" UK) as the stalwart, if edgy, Dr. John Watson, and Andrew Scott ("Lennon Naked") as the unassuming mastermind of evil, Jim Moriarty.
