Students from a university mystery club decide to visit an island which was the site of a grisly multiple murder the year before. Predictably, they get picked off one by one by an unseen murderer. Is there a madman on the loose? What connection is there to the earlier murders? The answer is a bombshell revelation which few readers will see coming.
