As the priest at a Catholic funeral mass brings the chalice to his lips, he falls over dead.
When Detective Lieutenant Eve Dallas confirms that the consecrated wine contained potassium cyanide, she's determined to solve the murder of Father Miguel Flores.
His autopsy reveals more. Faint scars of knife wounds, a removed tattoo, evidence of plastic surgery, suggesting that Father Flores may not have been the man his parishioners had thought.
Now, as Eve pieces together clues that hint at gang connections and an act of revenge, she believes she's making progress on the case.
Until a second murder, in front of an even larger crowd of worshippers - knocks the whole investigation sideways. And Eve is left to figure out who committed these unholy acts - and why.
Roberts has done it again.
