Students are spooked at the San Francisco School of Fine Arts, and Lily is called in to search for possible paranormal activity. In return she's been promised a trunkful of Victorian-era clothes recently discovered in a school storage closet.

But Lily finds something else: the body of a wealthy patron of the school. In between running the store and seeing her new boyfriend, Max—a 'mythbuster' who is uncomfortable with her witchcraft—she uses her sleuthing skills to try to solve the murder. Soon Lily senses something from the school's vintage clothes, but it's not the smell of mothballs—it's the unmistakable aura of evil intent.
