A list of fictional Dentons. Additions welcome.
Colonel (or General?) Denton (he doesn’t use his given name), a veteran of the United States Civil War and former town marshal who moves to London where he writes novels and solves mysteries in early Edwardian times. There are seven Denton Mysteries by Kenneth Cameron: The Frightened Man, The Bohemian Girl, The Second Woman, The Haunted Martyr, The Backward Boy, The Past Master and The Oxford Fellow.
Officer Denton in the short story “The Badger Game” by Joe Flynn (Guilty, November 1956). Officer Denton drives a police car but says nothing.
Bill Denton (“a nice-looking kid of sixteen, with sandy, crew-cut hair, dressed in blue jeans and a sweatshirt”), in The Mean Streets by Thomas B. Dewey.
Don Denton, in Donald E. Westlake’s short story “Good Night, Good Night” (included in The Curious Facts Preceding My Execution and Other Fictions, 1968). Don Denton hosts The Don Denton Variety Show, and the story is told over the course of one hour on a Wednesday night as he watches the show recorded live to tape earlier that day. It begins with Denton being shot in the stomach. By the end of the story he has deduced who his murderer is. Then he dies.
