Sherlock: The Great Game Finale Sneak Peek

Sherlock wraps up its too-brief, three-episode run tonight on PBS’ Masterpiece Mystery! with another strong entry, “The Great Game.” Based on an Arthur Conan Doyle short story, the adventure has Benedict Cumberbatch’s Holmes chasing after a terrorist who straps explosives to innocent people and has them deliver cryptic messages to our hero, with deadlines for him to solve the clues before the victims go ker-blooey.
