"The Mephisto Club"

Peccavi

The Latin word is scrawled in blood at the scene of a young woman’s brutal murder: “I HAVE SINNED”. It’s a chilling Christmas greeting for Boston medical examiner Maura Isles and Detective Jane Rizzoli, who swiftly link the victim to controversial celebrity psychiatrist Joyce O’Donnell – Maura’s professional nemesis and member of a secret society called “The Mephisto Club.”

On tony Beacon Hill, the club’s acolytes devote themselves to the analysis of evil: Can it be explained by science? Does it have a physical presence? Do demons walk the earth? Drawing on a wealth of dark historical data and mysterious religious symbology, the Mephisto scholars aim to prove a startling theory: that Satan and his demons actually exist among us.

With the grisly appearance of a corpse on the Mephisto Club’s doorstep, it’s clear that someone – or something – is indeed prowling the city. The members begin to fear the very subject of their study. Have they inadvertently summoned an evil entity from the darkness?

Delving deep into the most baffling and unusual case of their careers, Maura and Jane embark on a terrifying journey to the very heart of evil – where they encounter a malevolent foe more dangerous than any they have ever faced…one whose work is only just beginning.
