the Houdini Museum in Scranton, Pennsylvania. Under the pen name Andy Adams, Gibson is credited with writing at least five of the twelve novels in the Biff Brewster juvenile adventure and mystery series for adolescent boys: Brazilian Gold Mine Mystery, Mystery of the Mexican Treasure, Mystery of the Ambush in India, Egyptian Scarab Mystery, and Mystery of the Alpine Pass. In the 1920s, Gibson wrote two books on numerology for the publisher George Sully & Co. With his wife Litzka R. Gibson (née Gonser), he co-wrote The Complete Illustrated Book of the Psychic Sciences (Doubleday, 1966), a 404-page book which explains how to practice many popular forms of divination and fortune-telling, including astrology, tasseography, graphology, and numerology. Litzka wrote her own books on topics as diverse as palmistry, dancing, and personal hygiene, sometimes under the pen-name Leona Lehman. Gibson wrote a Batman prose story which appeared in Detective Comics #500 (March 1981) and was drawn by Thomas Yeates. Gibson also ghosted the novelization of the Preston Sturges screenplay The Sin of Harold Diddlebock under the by-line of popular humorist Harry Hershfield. Hershfield had been commissioned to write the novel, but stalled out in the first chapter. Gibson was engaged to write it in his stead, and the adaptive prose is actually his, from start to finish. Appearances and tributes in fiction He is a featured character in the Paul Malmont novel The Chinatown Death Cloud Peril, which was published by Simon & Schuster in 2006, and in the sequel The Astounding, the Amazing, and the Unknown (Simon & Schuster 2011). In addition, Gibson is the protagonist, along with Orson Welles, in a historical mystery by Max Allan Collins, The War of the Worlds Murder, published by Berkley Books in 2005. In the Dynamite Entertainment miniseries "The Shadow: Year One" by Matt Wagner, a reporter appears on more than one occasion throughout the story's progress, investigating most of the appearances of The Shadow and its connection with Lamont Cranston (Allard, who had in fact changed his identity with Cranston's). At the end of the story we are shown that the reporter is called Maxwell Grant. Although it is not an appearance of Gibson as such, it is indeed a reference and tribute to his work in the novels when Grant talks of trying to document part of the adventures of The Shadow.
