What are the motives behind the murders of all the guests? Each of the guests is guilty of a crime, but not one that could be prosecuted in a court of law. Does each receive his/her just deserts? In other words, has true justice been accomplished by the end of the novel? Is the murderer insane as all the guests claim? Or is he/she acting with clear-headed logic and rationality?
