Sherlock fans, clear your schedule: according to Vulture, its third season is heading online next Monday, and it'll be available to stream exclusively at Netflix. While it's certainly one of Netflix's smaller exclusives — after all, the season has already aired — the show has a passionate fanbase and has seen plenty of accolades. It also appears that Netflix may have locked up Sherlock's first two seasons as well, adding another big series to its roster. Netflix has been in a heated battle with Amazon and Hulu to lock up exlcusive content lately — some original, others just popular — and Sherlock serves as only a further piece of ammunition in the battle.
