Jean-Christophe Portes, writer and reporter, chose to take the readers for three months in immersion with the scientific investigators of the gendarmerie.
Hair, footprint, insect, drop of sweat, trace in the mud: the scientific experts of the National Gendarmerie track down the slightest element of crime scenes. For them, everything can be a clue to a case. Jean-Christophe Portes brings us for the first time to one of the most secretive forensic institutes in the world in Paris. These "super-experts" tell their daily lives through twenty or so cases, from the death of Diana to the crash of the Rio-Paris flight. An incredible profession where we juggle between chemistry, toxicology, genetics, biology, ballistics and explosives science. And very different from what TV crime shows us.
