By far the best book of Stéphane Bourgoin from Serial Killers who stands out as one of the biggest profilers in the world. After James Ellroy and major US investigators, Stéphane Bourgoin demolishes the ridiculous assumption that George Hodel never killed the Black Dahlia. His quest for the real murderer is incredible precision and ingenuity in duplication. Inlâchable superb book for me but warning for the photos: I think this is the first time that such violent images are broadcast in a book, so to prescribe for children under 16 years.
