Hound of the Baskervilles
Wed-Thu 7:30pm; Fri 8:00pm; Sat 3pm & 8pm; Sun 2pm (through 10/2)

Three actors, sixteen roles… The fast-paced production is a comedic retelling of the classic Sherlock Holmes novel by Sir Arthur Conan Doyle, which tells the tale of an attempted murder inspired by the legend of a phantom hound.

The theater is comfortable and small enough so most seats are close to the action. Kids can enjoy the actors’ quick costume turnarounds, spooky music, and sight gags and still get the whole story of The Hound of the Baskervilles.

Cost: $15-$45. Ages: 12+
