From the moment Jennet move in with the other students working on archaeological digs in beautiful York, England, someone seems to be setting her up as a thief. Small things disappear, and her dormmates make ugly insinuations. Then, disaster: an exquisite medieval chalice uncovered in the St. Oswald's dig is stolen. By this time, Jennet has suspicions of her own.
