Chubby, brunette Eunice Kinnison sat in a rocker, reading the Sunday papers and listening to the radio. Her husband Ralph lay sprawled upon the davenport, smoking a cigarette and reading the current issue of EXTRAORDINARY STORIES against an unheard background of music. Mentally, he was far from Tellus, flitting in his super-dreadnaught through parsec after parsec of vacuous space. E.E. "Doc" Smith, Triplanetary, Chapter 5: "1941"
