Play by Norman Robbins.

Set in a sinister old library, presided over by a portrait of a grim-faced, mad-eyed old man, a dusty lawyer reads a multimillion-pound will to an equally sinister family, one member of which was werewolf tendencies, another wanders around in a toga of Julius Caesar, and a third member is a gentle old lady who plants more than seeds in her flower beds. By the third act, there are more corpses than live members left in the cast. Are they all they seem to be? All is revealed as the plot twists and turns to its surprising conclusion.
