Murder and mystery abound in this ingenious play from the master of the genre. Initially the plot seems to concern a greedy husband plotting to kill his wife. Disposing first of his brother-in-law, Jack enlists the help of his girlfriend in his plan to murder Sarah. But his scheme goes horribly wrong and he, not his wife, ends up dead. There are so many possible suspects and motives that the truth eludes us all ... although Cliff seems to be on the right track.
