When Lily arrives at an antique jewelry fair, 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 that nods to an old-fashioned witch hunt. A crime that hits close to home turns into an unwelcome flash 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.
