Sherlock faces his biggest challenge of all – delivering a Best Man’s speech on John’s wedding day. A case of stolen letters leads Sherlock Holmes into a long conflict with Charles Augustus Magnussen, the Napoleon of blackmail, and the one man he truly hates. But how do you tackle a foe who knows the personal weakness of every person of importance in the Western world? MASTERPIECE: "Sherlock: The Last Vow" airs Sunday, February 2, 2014 at 10 p.m. on WXXI.
