As the owner of a popular vintage clothing store, Lily Ivory can enjoy a day of antique jewelry shopping and still call it work. But since she is one of San Francisco's resident witches, searching for hidden treasures can sometimes lead to dangerous discoveries. When Lily arrives at a gem fair--full of antique jewelry, rare stones, and decorative tchotchkes--her bargain sensors go off left and right. But she also picks up a faint vibration of magic. Could the hard-bargaining merchant Griselda be a fellow practitioner? It certainly seems that way when a sudden fire sends panic through the crowd and Lily discovers Griselda murdered in a way reminiscent of an old-fashioned witch hunt. A crime that hits close to home turns into an unwelcome blast from the past when the police bring in their lead suspect--Lily's estranged father. Though he may not deserve her help, Lily is determined to clear her father's name and solve a murder that's anything but crystal clear.
