Sherlock on Masterpiece

In this contemporary version of Sir Arthur Conan Doyle's detective stories, Dr. John Watson is a war vet just home from Afghanistan. He meets the brilliant but eccentric Holmes when the latter, who serves as a consultant to Scotland Yard, advertises for a flatmate. Almost as soon as Watson moves into the Baker Street flat, they are embroiled in mysteries, and Sherlock's nemesis, Moriarty, appears to have a hand in the crimes.
