Ashes to Ashes - S3.E21

When an anonymous tip leads NIck to a "headless corpse" in the Raven, it is only the beginning of a deadly game, with vampires as the target. Nick soon discovers the ultimate target in these murders is LaCroix. Anyone and everyone who is close to LaCroix are being killed. When LaCroix reveals that the perpetrator is Divia, his daughter and master who he betrayed long ago, it becomes a race against time for Nick to find her before she comes for him or LaCroix.
