The Man Who Murdered Sherlock Holmes (Mercury Theater). The Baker Street sleuth and his creator, Arthur Conan Doyle, team up to sing, dance, and redress a real-life miscarriage of justice. The case's deeper issues get slighted in John Reeger's script, but the show is an entertaining whodunnit with a top-flight cast. Through March 20.
Le Switch (About Face Theatre). A gay New Yorker remains ambivalent about the legalization of same-sex marriage, even after he meets a sweet and sexy flower vendor from Montreal. As in his previous work, playwright Philip Dawkins displays a knack for portraying contemporary LGBT life with an endearing mix of warmth and wisecracks. Through February 21.
London Wall (Griffin Theatre Company). John Van Druten's rarely revived 1931 workplace comedy about the typists at a London law office and the cocky young solicitor who thinks he’s God’s gift to them. Robin Witt’s crisp, period-perfect production is filled with sparkling performances. Through February 14.
The Year of the Rooster (Red Theater). A born loser pins his hopes on a rooster whose kill-everything philosophy makes him a natural in the brutal world of cockfighting. Jeff Kurysz plays the bird with a strangely affecting combination of aggression and vulnerability. Through February 6.
