Mauvaise foi

In the silence of a Carmelite convent, Sister Amélie is found murdered in a penitential position. Was she killed by the angry father who accused her of having enlisted his daughter, a young novice who was about to take her vows?

Under the gothic vaults of the cloister or in the intimacy of the cells, Mongeville and Valentine will have to keep the faith to unravel an investigation where piety reveals multiple faces...
