Watch Sherlock Holmes Online – The film, set in London of 1891, opens with Holmes (Robert Downey, Jr., Watson (Jude Law) and James ([Lawrence Chiru]) racing to prevent a human sacrifice ritual conducted by Lord Blackwood (Mark Strong). Holmes and Watson stop the sacrifice just in time and neutralize Lord Blackwood, after which the police, led by Inspector Lestrade (Eddie Marsan), arrive and arrest him. Blackwood’s hanging occurs three months later, during which Holmes has become bored without a new case, while Watson prepares to move to new quarters to share with Mary Morstan (Kelly Reilly) whom he intends to wed. Blackwood requests Holmes’ presence on the day of his execution. Holmes finds that Blackwood has seemingly mystic powers, causing one guard to be struck with a seizure and scaring the other guards and prisoners, while having written numerous occult symbols on his prison cell. Blackwood promises to Holmes that there will be three more deaths after his execution that will change the very nature of their world. Blackwood is executed, declared dead by Watson himself. – read more
