Punish the Sinners — John Saul

Italy 1252. Inquisition. Accusation. Fear.  Torture. The guilty and the innocent dying for sins real  and imagined in the flames of the burning stake.  Neilsville, 1978. Peter Blasam has come to this  sleepy desert town to teach its youth, and finds a  mystery of mounting horror. Something is happening  to the young girls of St. Francis Xavier High  School -- something evil. In bloodlet and terror a  suicide contagion has swept the two... while a dark  order of its holy men enacts a secret medieval  ritual. Is hysteria manipulating these innocent children  into violent self-destruction? Or has supernatural  force, a thirteenth-century madness, returned  to... Punish The Sinners.
