    MacDonald is far more widely known for his authorship of the "Travis McGee" detective novel series than he is for a couple of SF titles and a handful of short stories. My wife has read virtually of of "McGee" and had no idea that MacDonald had written any SF at all. – Emsley Wyatt Feb 25 '18 at 15:27
