Merci papa, merci maman

A charred body is found in Brocéliande Forest with a shocked and speechless 13-year-old boy next to it. What is he doing there? How is he involved? Two gendarmes and an unconventional child psychiatrist try to clear up the mystery.

Police Captain Kader Cherif knows the city like the back of his hand, and, as someone could say, never leaves his duty, because his apartment located on the first floor of the building opposite to the police station. He is assigned to investigate unusual murders in Lyon. Of course, he is using only legitimate methods which sometimes seem to be unusual and are displeasing his new partner Adeline Briard, police captain as well.
