Milton Halverson, a rapist and murderer who escaped justice, has just been found hanging in his basement, a victim of an occult ritual. Detective McKenna is given the investigation, and thrust back into a case that was mothballed … because he made a mistake. Milton was that mistake. Someone has brought justice, but justice may be a vigilante to be feared. As Detective McKenna and his partner press reluctantly on the case they find it intimately tied to a rapist terrorizing universities they have been unable to catch, and to a very old and dark occult ritual. Clues and evidence that once lead nowhere are now coming together on a single malevolent path. An expert on the occult is brought in and her unexpected ties to the case casts them all into a web of lost romance, inner demons, and painful memories that lead them all closer to the truth, and the rapist they are trying to stop before he attacks again. The devil is more than in the details. This devil is at the core of the attacks, and she has a plan.
