A New Comedic Mystery by Steven Gallagher

Main Season
July 9th - 12th 2026
About

On a dark and stormy night at Ackerton Manor, the loathed Roger Ackerton meets a deadly end. Enter Detective Pierre Pierrot, armed with only a corpse, a missing diamond, and five eccentric suspects — each with a motive more absurd than the last. In this whirlwind tribute to Agatha Christie, three actors bring seven outrageous characters to life. Twists, turns, and mistaken identities keep the laughs, and bodies, coming.
