When history buff and multi-lingual American tech writer Annie Young returns to her studio nest in Southern France from her Zurich assignment, she can hardly wait to see what Pere Yves has to tell her about the research they had been sharing in nearby Rennes-le-Chateau.
Instead, she finds the priest's body crumbled on his church's steps. While she is calling the police, the body disappears. The police think it is her way to get Police Chief Roger Perrin's (her ex-boyfriend) attention, but he knows better. The police have no clues, even after the body is found in an ancient stone tomb in the church.
