A finalist for the National Book Award and winner of the Edgar Allan Poe Award, it has been adapted into an upcoming film directed by Martin Scorcese. His other bestsellers include The Lost City of Z, the nonfiction tale of the deadly search for a fabled Amazonian civilization; and The Devil and Sherlock Holmes, named by Men’s Journal as one of the best true crime books ever written.
