It's Blasphemer's Week, the annual period during which the gods vacation at Mount Olympus and ignore the inconsequential mortals, and it always begins with blood. This year's first victim is a former police officer, murdered while getting butter from his fridge. Now, Virgil Glezos, the city-state's first detective on his first case, must track the killer by inventing techniques that combine magic and technology. He is aided by a professional dance choreographer, a bio-warfare expert who doesn't want to be there, two police officers who hate him, and a priest who may or may not be trying to kill him. When Virgil uncovers something deeper than a single murder, he must quickly become the wrong person at the right time to stop the greater plot against humanity.
