For the most part, events occur in this novel when they occurred in reality (an exception is the slaying of Max Hassel and Max Greenberg, which was shifted in time somewhat). Most of the characters in this novel are real and appear with their true names, and the occasional fictional characters have real-life counterparts (notably, Tim O’Neil and Harlan Jensen). The characters Martin Marinelli and Sister Sarah Sivella are composites, primarily suggested by one real-life husband-and-wife psychic team; however, the tryst between Heller and Sivella has no basis whatever in history. Inspector Welch is a composite character. Heller’s role as police liaison was suggested by the real-life roles of Chicago’s Pat Roche and Lt. William Cusack, both of whom went to Hopewell; and Governor Harold Hoffman (and Evalyn McLean) did hire a number of private investigators to work on the Hauptmann case.
Bob Conroy and his wife indeed died in a “double suicide,” after Conroy had been pointed out to the authorities as the probable kidnapper by the incarcerated Capone; but my speculation about the real role of the Conroys in the kidnapping is just that: speculation. The false alarm on Sheridan Road in the first chapter, however, is loosely based on fact.
Several hardworking people helped me research this book.
George Hagenauer, whose many contributions include developing an extensive time chart of events, spent hours in libraries gathering book and newspaper references, and on the phone discussing with me the ins and outs of this complicated and very strange case. He also went to Virginia Beach to do Edgar Cayce research, and toured the Indonesian Embassy (the former home of Evalyn McLean at 2020 Massachusetts Avenue) in Washington, D.C. George is a valued collaborator on the Heller “memoirs” and I appreciate his contribution as much as his friendship.
Lynn Myers, one of the nicest people I know, dug in and did research rivaling George’s. Against considerable odds, he rounded up the voluminous and invaluable
Mike Gold, a Chicago history buff with an eye for detail, provided a vivid impromptu telephone tour through LaSalle Street Station. Dominick Abel, my agent, provided some tough, valuable advice midway that helped shape this novel. My keen-eyed editor Coleen O’Shea deserves special thanks for her longtime interest in, and support of, Nate Heller and his coauthor; thanks also to editors Charles Michener (who, among much else, helped come up with a title) and Marjorie Braman.
Other tips of the fedora for support along the way go to my old high-school pal Jim Hoffmann (who provided a videotape of the 1976 TV docudrama,
Mickey Spillane provided information about Elizabeth, New Jersey, and put me in contact with his friend Walter Milos, who did extensive research and legwork on the Elizabeth Carteret Hotel. Thank you, gentlemen.
