How Sherlock (Benedict Cumberbatch, The Last Enemy, War Horse, The Hobbit) manages to survive snipers, explosives, and a poolside face-off with his insane arch-nemesis Moriarty — or end up in Buckingham Palace’s inner chambers, clad only in a sheet — are just the initial tantalizing questions answered when Sherlock returns with its gripping second season opener, A Scandal in Belgravia. The central enigma concerns Irene Adler (Lara Pulver, True Blood), a beautiful entrepreneur whose special relationship with the rich, powerful and royal has allowed her to amass coveted information powerful enough to topple the government. A worthy match for the aloof detective, Adler masterfully maneuvers her many assets in a game that Sherlock is ill-prepared to fight: love. Two brilliant minds lock together, producing a heat that brings a blush to John’s cheek and a potential change to a celibate, cerebral detective. But who will come out on top? Award-winning series co-creators and producers of Doctor Who Steven Moffat and Mark Gatiss reunite favorites Dr. John Watson (Martin Freeman, The Office UK, The Hobbit) and Mrs. Hudson (Una Stubbs) in an all-new adventure. (One episode; 90 minutes, TV-PG)
