When Eugenia Potter picks up some pot shards and carved shells on her ranch near Tucson, Arizona, she decides that she is meant to discover the people who lived there years ago. Remembering a brochure advertising a "Hike Into History" at the Medicine Wheel Archaeological Camp in Cortez, Colorado, she calls and reserves a space on the next class starting in two days. Quickly packing and grabbing a supply of Sweet Dream cookies, she climbs into her car and heads it towards Colorado. When she arrives, she discovers that her hiking class is made up of eight women, all but two of which are definitely on the mature side. Also at the Camp are a group of 16 gifted high school students from a prep school in Texas. When one of the hikers is found dead, then a young archeologist killed in a fall, and the whole 16 students disappear, Genia decides it is time to put her detecting skills to work. In the second of the Eugenia Potter mysteries written by Nancy Pickard and based on the late Virginia Rich's character and notes, the souls of mature women are captured in an archeological rich story.
