Rocket to the Morgue
The society and many of its members appear, thinly veiled, in Boucher's Rocket to the Morgue, whose dedication (in the first edition, read "For The Mañana Literary Society and in particular for Robert Heinlein and Cleve Cartmill." Rocket to the Morgue is something of a roman à clef. Many characters are thinly-veiled versions of personalities such as Robert A. Heinlein ("Austin Carter"), L. Ron Hubbard ("D. Vance Wimpole"), then-literary agent Julius Schwartz ("M. Halstead Phynn") and rocket scientist/occultist/fan Jack Parsons ("Hugo Chantrelle"); or recognizable composites of two writers ("Matt Duncan" - Cleve Cartmill and Henry Kuttner; "Joe Henderson" - Jack Williamson and Edmond Hamilton). Some writers' actual pseudonyms appear as minor characters, most prominently "Don Stuart, editor of Surprising" (John W. Campbell, editor of Astounding Science Fiction); but also "Anson Macdonald", "Lyle Monroe" (both Heinlein pseudonyms)... and Anthony Boucher (whose real name was William Anthony Parker White).
