Who Stole the Necronomicon?

Wisdom flowers in Arkham-with blunt force trauma. The Arkham Detective, now a private investigator, shadows the biggest theft ever to hit Arkham, Massachusetts. Someone stole the Book of the Dead, and a series of gruesome murders leave a trail to the ruins of the old Witch House; a place known for its hauntings and an unsolved homicide. Victims are left with fist-size gaping holes torn through their bodies. Our detective from Arkham is the only one capable of tracking down the culprits and the unearthly. Tasked with not only finding out the "who," he needs to find out the "why?"
