A dead man leaves his money to his father and niece, but who is the dead man? A man's body lies on a narrow ledge in a remote Arizona canyon, but who is he? Is the old gold mine really a mine? Why was the girl murdered behind the mountain cabin? What's it like to be lost in a desert mountain range without food, water, or shelter? Finally, who are the mysterious riders, and what are they up to in the dead of night?

Join Art Parker, his daughters Heather Parker and Mary Ann Markham, and their best friend Jennifer Martin as they travel to southern Arizona to try to answer these questions and stumble upon the solution to several murders as well as other illegal activities. The Cochise County Sheriff's Department is not amused, but that's a normal reaction to this team of amateur sleuths.
