In the heart of the Carmel of Lisieux, the statue of St. Theresa seems to be alive. Miracle? Not. It is a staging to conceal the corpse of a murdered young woman. Commander Thomas Renaud and Lieutenant Laurene Leterrier are responsible for elucidating this unusual murder that will lead them into the footsteps of St. Theresa. They will then have to team up with the last person they thought of, Sister Angele, a Carmelite from Lisieux.
