While researching his new book, Astounding: John W. Campbell, Isaac Asimov, Robert A. Heinlein, L. Ron Hubbard, and the Golden Age of Science Fiction, author Alec Nevala-Lee learned that Campbell had actually written a novel-length version of [“Who Goes There?”], which he cut down for publication in the magazine.
