Something is definitely off at Lord Edgar Hillcrest’s eerie Victorian mansion, Mandacrest. The recently widowed Egyptologist has brought his new bride home to greet the crude characters who populate the premises, including a one-legged stable boy, a frumpy maid with secrets and a couple of terrifying, other-worldly creatures. The dizzying array of eight characters is trumped only by the play’s crowd-pleasing conceit: all are played by two lone, multi-costumed actors. The horror, the romance, the sheer shamelessness of the whole thing; The Mystery of Irma Vep is certain to knock audiences silly.
