The Amazing Mrs. Mimms [EPUB ebook] 

“Long may the good lady serve us poor folks in the dim past, ” writes the author, who will be remembered for his THE LOVE OF FRANK NINETEEN (Dec. 1957) and who feels that much of SF “misses” because it lacks the human angle. “I believe you can have gimmicks and human interest too, ” he writes.
