Riddle me this voodoo clue...
An unearthly hue.

Logan Malone decides they have to start back at the beginning, so he and Presley Kincaid go visit Carson Del Vecchio's mother. They believe something is tying his ghost to this world and maybe she kept a bit of hair from when he was a baby. That turns out to be a dead end but they do learn Del Vecchio has a half-brother whom Logan wants to question later.

Frustrated, Logan takes Presley to a supernatural nightclub to talk with an old voodoo priest, hoping to get answers. They find out since Presley died, she has a glow that supernaturals can see, which is how Del Vecchio finds her. The priest also informs them that someone must have brought Del Vecchio back from the dead in a dark ritual and gives Presley a charm to disguise her glow. But before they can get home, another brutal homicide is reported.

They hurry to the murder scene, but more than one familiar face is lurking there, and Logan decides it's time to go on the offensive—before Presley runs out of time.

This is Episode 4 of 5 in Edge of Darkness from the Paranormal Investigations Unlimited Series.
