Acknowledgments

My deepest appreciation for their help goes to Calista Lucy, Dulwich College Archivist; to Mariusz Gasior, Access Team Librarian at the Imperial War Museum; to Chris Morton, Information Manager of The National Gallery; and to Roger Johnson, editor of The Sherlock Holmes Journal. On a more personal level, many thanks again to Barry Smolin, Sandy Cohen, Seth H. Victor, Ethan J. Victor, and Robert and Sylvia MacDowell. But the greatest thanks and love go to my wife, Norma Silverman, without whose inspiration - in more ways than I can count - this project would never have been conceived, let alone completed.
