See Sherlock as you’ve never seen her before in "Miss Holmes," as Sherlock and Watson are both women in the Greater Boston Stage Company's play opening April 5th. Jamaica Plain's Marge Dunn is playing Sherlock Holmes in the play that was written by Christopher Walsh, and based upon the characters by Sir Arthur Conan Doyle. “I love a good mystery,” said Weylin Symes, director and producing artistic director. “When I found Chris Walsh’s version of Sherlock Holmes, I immediately knew I wanted to produce it. The idea of a traditional Sherlock Holmes mystery with a female Holmes and Watson is so simple, elegant and obvious that I’m surprised no one thought of it before now.
