Local author Steven LaChance will sign and discuss his new book, “Confrontation with Evil: An In-Depth Review of the 1949 Possession that Inspired The Exorcist.”

Known as the 1949 St. Louis Exorcism, the story of possessed child Roland Doe was immortalized in the groundbreaking novel and film The Exorcist. Much has been written about the case, but the truth has been shrouded in secrecy…until now. Join Steven A. LaChance, as he shares the shocking evidence for how a family’s grief over the death of an aunt progressed into a full-blown demonic possession. While the conventional story is that Roland Doe brought the demonic infestation upon himself, LaChance convincingly suggests an alternative interpretation, and provides new insights into the nature of possession itself.

This event is free and open to the public, but proof of purchase of “Confrontation with Evil” from Left Bank Books will be required to enter the signing line.
