An astonishing story that has never been revealed to the public, The Pope's Butcher recounts the life of Father Heinrich Institoris, the Grand Inquisitor, a visionary man driven to cleanse the world of Eve's original sin by eradicating any woman he suspects of witchcraft. As Inquisition courts bloom across Europe, he vows to leave no stone unturned, no hovel unexamined, and no woman alive, in his search of his own perverse version of justice.

At a time when women had no power or voice, only one man seeks to stop him. The reader follows the life of Sebastian, a young seminarian who was abandoned as a child but carries with him an innate sense of morality that drives him to stand up for even the most vulnerable victims against his own Church. Will such a humble man be able to stop this powerful murderer, a killer even the Pope admires?
