France's leading forensic pathologist, Philippe Charlier, delves into the mystery of Saint Joan of Arc's remains, which were supposedly discovered in 1867 after being lost for centuries. Charlier, known as the "Indiana Jones of graveyards," approaches the investigation like a medical case, viewing the bones as patients rather than archaeological artifacts. The relics, including bones and a textile fragment, spark debate over their authenticity, with some believing them to be a hoax. Through various scientific methods including DNA analysis, CT scanning, and chemical analysis, Shaler attempts to determine if the remains truly belong to Joan of Arc.
