One of the revelations of the police in 2010, the Whisperer is a captivating thriller, remarkably built and documented (it is not surprising that the author is specialized in criminology). Opening the book with the discovery of buried 6 arms raised fears an escalation in a moment of horror that becomes tiresome in many current thrillers. But the novel takes an original direction for the discovery of each corpse updates of old crimes, psychopaths works that the police never managed to catch. One of the other strengths of the novel is its ability to dispel many myths about serial killers and investigative profilers methods. Writing is never neat and simplistic fine in the psychology of the characters, especially that of the interviewer, a young woman specialized in child abduction and marked by an old trauma that the author reveals over the plot. In short, a great cop. We only regret improbabilities small and a little coarse effects of outcome that are below one-rest of the book.
