Hell is other people, and Mary lives with Mother and Uncle Henry. In Mary's dream, her mother and uncle have murdered twenty three people and now the Devil arrives to exact retribution. He puts an idea into Mary's head, and when she wakes to her hellish reality, she carries out his suggestion with startling effect. But is she going to hell for her crime, or has she just left it? Easy to stage, this compact play combines the elements of surprise and satirical humour with a macabre and effective twist in its tail.
