Who leaves a wedding early? In The Sign of Three, it’s the best man, namely Sherlock (Benedict Cumberbatch, The Fifth Estate, Star Trek: Into Darkness). John Watson (Martin Freeman, The Hobbit, The Office UK) may live to regret offering the role to a man who didn’t realize he was John’s best friend, but more importantly, one of the guests at John’s wedding to Mary Morstan (Amanda Abbington, Mr. Selfridge) may not live to see the end of the day.
Too bad that Sherlock is unable to focus his tremendous powers of deduction on the murder that’s hatching right under his nose, but then the responsibilities of a best man are more diabolically exhausting than preventing a very clever killing. Written by Steven Moffat and Mark Gatiss, award-winning series co-creators and producers of Doctor Who, and Doctor Who writer Steve Thompson, The Sign of Three presents a “night do” of a wedding to remember. (One episode; 120 minutes, TV-PG)
