Ellery Queen is a pseudonym created in 1928 by the American detective fiction writers Frederic Dannay and Manfred Bennington Lee. It is also the name of their main fictional detective, a mystery writer in New York City who helps his police inspector father solve baffling murder cases. From 1929 to 1971, Dannay and Lee wrote around forty novels and short story collections featuring Ellery Queen as a character. "The Adventure of the Emperor's Dice" was originally written as a script for the Ellery Queen radio drama series and aired on March 31, 1940. It was then adapted into short story form by Frederic Dannay and Manfred B. Lee, the two cousins who wrote under the pseudonym Ellery Queen. The short story version was first published in the April 1951 issue of Ellery Queen's Mystery Magazine. It was included later that year as one of the stories in the anthology collection Calendar of Crime, published by Little, Brown and Company, as part of their year-long series of monthly murder mysteries. In both its radio play and short story iterations, "The Adventure of the Emperor's Dice" featured the character Ellery Queen, his father Inspector Richard Queen, and secretary Nikki Porter investigating a baffling murder case involving an inherited set of ancient dice. In the late 1920s when Dannay and Lee first created the Ellery Queen character and stories, the detective fiction genre was still heavily influenced by the "Golden Age" embodied by writers like Agatha Christie and the clue-puzzle mysteries popularized in the 1920s. The Ellery Queen mysteries represented an American take on this tradition, with intricate plots and a focus on following clues and deductive reasoning. However, by the 1940s when "The Emperor's Dice" first aired as a radio play, the genre was starting to evolve with the rise of hardboiled detective fiction spearheaded by writers like Dashiell Hammett and Raymond Chandler. Their pioneering work injected more gritty realism into crime stories. "The Emperor's Dice" straddled these two eras. While adhering to the classic clue-puzzle format the Queen stories were known for, it also incorporated more modern elements like an atmospheric opening scene, hints of psychologically damaged characters, and flashes of noir-esque descriptions. When it was published in print form in 1951's Calendar of Crime anthology, detective fiction was further evolving with writers like John D. MacDonald blending elements of the traditional and hardboiled styles. "The Emperor's Dice" can be seen as an important transitional work that helped evolve the American detective novel from its golden age into a more modern psychological suspense style. With its deft blending of puzzle-solving and mood, clever plotting and character insights, "The Emperor's Dice" exemplified how Dannay and Lee masterfully kept the Ellery Queen stories vital and distinctive even as the genre changed around them. It remains an influential and important work in the development of American mystery writing. Learn more about your ad choices. Visit megaphone.fm/adchoices
