"The year is 1896. The city is New York. Newspaper reporter John Schuyler Moore is summoned by his friend Dr. Laszlo Kreizler--a psychologist, or "alienist"--to view the horribly mutilated body of an adolescent boy abandoned on the unfinished Williamsburg Bridge. From there the two embark on a revolutionary effort in criminology: creating a psychological profile of the perpetrator based on the details of his crimes. Their dangerous quest takes them into the tortured past and twisted mind of a murderer who will kill again before their hunt is over"--From the publisher.
