Caleb Carr wrote historical crime and suspense, best known for The Alienist. Set in 1890s New York, the novel follows psychologist Laszlo Kreizler, journalist John Schuyler Moore, Sara Howard and a small investigative team using emerging ideas about psychology and forensics to pursue a serial killer targeting boys. The Angel of Darkness returns to the same group for another case involving kidnapping and murder. Carr also wrote military and historical non-fiction, but his fiction is especially associated with the darker side of Gilded Age New York. His prose is detailed, atmospheric and procedural, fitting historical thriller, serial-killer fiction and early-forensics crime. The Alienist is the defining entry point, combining period New York with an investigation built around emerging criminal psychology. Read more Less
