Murder at the 42nd Street Library follows Ambler and his partners in crime-solving as they track down a killer, shining a light on the dark deeds and secret relationships that are hidden deep inside the famous flagship building at the corner of 42nd Street and Fifth Avenue.
In their search for the reasons behind the murder, Ambler and his crew uncover sinister, and profoundly disturbing, relationships among the scholars studying in the iconic library. Included among the players are a celebrated mystery writer who has donated his papers to the library’s crime fiction collection; that writer’s long-missing daughter, a prominent New York society woman with a hidden past, and more than one of Ambler’s colleagues at the library. Shocking revelations lead inexorably to the traumatic events that follow—the reading room will never be the same.
Even more startling, the late curator was involved in the Priory of Sion—a secret society whose members included Sir Isaac Newton, Victor Hugo, and Da Vinci—and he guarded a breathtaking historical secret. Unless Langdon and Neveu can decipher the labyrinthine puzzle—while avoiding the faceless adversary who shadows their every move—the explosive, ancient truth will be lost forever.
