The bloody scribbling of the Latin phrase appears at the spot where a young lady was brutally murdered. For Boston medical examiner Maura Isles and Detective Jane Rizzoli, it's a terrifying Christmas greeting. They quickly connect the victim to controversial celebrity psychiatrist Joyce O'Donnell, who happens to be Jane's professional rival and a member of the Mephisto Club, a diabolical organization.

The club's followers spend their time on top of Beacon Hill delving into the question, "Can science explain it?" Does it exist in the real world? Are there devils on Earth? By using an abundance of sinister historical information and enigmatic theological symbolism, the Mephisto researchers want to shockingly demonstrate that Satan himself is among us.

It's obvious that someone—or something—is definitely scavenging the city when a body appears horrifyingly on their doorstep. The club members start to become afraid of the same thing they are studying. Is this insane murderer one of their own, or have they unintentionally called forth a malevolent force from the shadows?

Maura and Jane go on a scary trip to the very center of evil, where they come with a cunning adversary more deadly than any they have ever encountered—one whose job is just getting started—after delving deeply into the most perplexing and peculiar case of their lives.
