First edition. PBO. Perma Books M-4082. Near fine, unread copy in pictorial wrappers. A high-priced call girl who knew too much about too many men, and they had too much to lose if she talked, is found murdered. Four people confessed to her murder --- much of the evidence points to one of them in particular. Dr. Michael Gray thinks that none of them is guilty. The killer is still at large!!
