A small child wanders across a busy Arizona highway! In a hair-raising rescue, sixteen-year old twins Tom and Suzanne Jackson save the little girl from almost certain death. Soon, the brother and sister team up with best friends Kathy and Pete Brunelli on a perilous search for the child’s past. The mystery deepens as one becomes two, forcing the deployment of secretive technology tools along Apache Canyon Drive. The danger level ramps up with the action, and the “mystery searchers” are born.

There’s a dead man walking and it’s up to the mystery searchers to figure out “why.” That’s the challenge from Mrs. Leslie McPherson, a successful but eccentric Prescott businesswoman.
