Prepare for tricks, treats, and time travel! In honor of Halloween, we’re traveling back to the mid-seventeenth century to investigate a case of demonic possession and the practice of exorcism in New France.

Mairi Cowan, an Associate Professor of History at the University of Toronto, Mississauga, joins us to investigate the life of a young French woman named Barbe Hallay and her demonic possession. Cowan is the author of The Possession of Barbe Hallay: Diabolical Arts and Daily Life in Early Canada.
