Vagabond Players’ centennial season, filled with works the company successfully staged in decades past, includes "Something’s Afoot," a musical spoof of Agatha Christie’s “Ten Little Indians.” Sure, it was a flop on Broadway in 1976, but has long been popular elsewhere. This revival should offer a clue why. Oct. 16 to Nov. 15 at Vagabond Players, 806 S. Broadway. $16 to $24. ?410-563-9135. vagabondplayers.org.
