Patti has found that having a "keen, analytical mind" as her teachers call it might be a great help studying science which she loves but it has not done much for her social life. The summer camping trip with her two cousins, Jolene and Juliebelle, was supposed to help, but camping with two battling sisters is no help for anything. At Golden Groves campground, however, things begin to change for the better, at least for Patti, with the arrival of a handsome camper who is smart enough not to be roped in by Jolene. Then, on her morning nature walk, Patti finds a corpse. Who better to look for clues than someone with a "keen, analytical mind" like hers?
