Bruno, Chief of Police, returns to investigate a case of Satanism in the South of France Springtime in St Denis. A female body has been found on a boat, bearing the ghastly signs of a black magic ritual. The victim is unknown and nobody is coming forward. This is the last thing Bruno needs, with too much on his plate as it is. But Bruno soon finds himself back at his best; which is just as well if he's to solve the mystery that's threatening to scar his town's reputation.
