After the disappearance of wealthy Edmond Connicle, his wife hires Colin Pendragon and Ethan Pruitt for the investigation, which intersects with Inspector Varcoe’s suspicion towards the Connicles’ West African maid, especially after a body is found on the estate. As more bodies surface, Varcoe and Pendragon must collaborate, examining if the motive is rooted in Voodoo or if a more mundane madness is driving the killings.
