Nine Man's Murder

Nine graduates of Damien Anderson's Detective Training Agency assemble at an isolated vacation home for a class reunion, but their host remains elusive ... until he is found dead in a closet. Soon thereafter, the murders begin. One by one, the graduates are eliminated by a mysterious person who has decided to pit his or her wits against the guests'. As a snowstorm traps the party, the survivors realize that the murderer must be one of them. Yet the killings continue, despite locked doors and windows. What is the killer's motivation? Is an old grudge at work? Could the explanation be related to a series of mysterious accidents on the set of a film titled Nine Man Morris, which the classmates had investigated fifteen years earlier?
