MacDuff: Murder Strikes Three

"A short and hard-boiled tale of the murders of a college professor and two of his colleagues. Facing Detective Reuben Mallock are several problems, among them the appearance of the professor’s monstrous son on the day of the murder, the silence of a beautiful young woman who seems to know more than she is willing to tell, and an acute case of jitters on the part of a group of racketeers."
