A man is found dead on the Path if the Oenitents in Rocamadour. Everything seems to indicate that he had been on a pilgrimage of expiation. But the investigation takes an unexpected turn when the dead man seems to show up among the living.

The body of a man is found on the stairs of the penitent's way, in Rocamadour. Before he died, he was forced to make an expiatory pilgrimage, just like in the Middle Age. A few days from retiring, Major Sophie Lacaze has to work on the case with her replacement to solve this mystery.—Happy_Evil_Dude
