Romance teams up with archaeology here for a teen age level of studious tone. The setting is Cordova Island on Puget Sound (a territory already written about by the authors in Stormy Year and Mystery of Catesby Island) and the task is to find the long house of Chief Yallocom, who had been alive at the time the whites first came. Working on the digging site are a group of students from a Washington University, led by Paul, an instructor, and his wife Cicely. They are all intent on their work but the first disturbance in their routine is Barbara, Cicely's flighty younger sister who would be gayer than the students are. The second is a local skeleton. The feelings it rouses among the local people against the students threatens to destroy their project and their futures. But all turns out well. Cordova will become a beneficial state park and Barbara becomes serious enough to attract one of the students.
