Corpse! is set in London in 1936, and tells the story of twin brothers, one of whom plots to murder the other in the most unusual circumstances. Evelyn, an out-of-work actor, engages the genial Irishman Powell, with a shady past, to do away with his suave, sophisticated, monied twin. Their plotting in Evelyn’s Aladdin’s cave of a flat is punctuated by the visits of a delightfully theatrical landlady. As with most foolproof plans, things do not go as they should and people are not what they seem. Corpse! is not so much a whodunit as a whodunit to whom!
