Victoria "Rab" Rabinowski couldn't believe that her first case since transferring back to the Robbery-Homicide division was a simple Breaking-and-Entering. Yet nothing is ever simple. When she arrives at the crime scene in the Palace Hotel, she learns that the Cup of Dionysus, a magical object of untold power, was stolen out of thin air. And that she won't be working alone. Joining her is her new partner, Harriet June - the newest Forensic Witch on the force.

But the case proves more challenging than they thought. With scarce clues and no eyewitnesses, even with Harriet's magic guiding the way, the detectives have more questions than answers.

Things take a turn when a person of interest, a hotel maintenance worker, is found fighting for his life after being afflicted with a dark, mysterious hex. From there, Rab and Harriet will piece together the leads to a conspiracy of death that shadows the case of the Dionysus heist.
