Notes:
"This edition first published in 1973 in Great Britain". No statement of printing, no number line. "First hardcover printing for both titles" - L.W. Currey. Title page states "Two Science Fiction Novels"; at 102 & 111 pages, neither really qualifies. Spine has only The Three Eyes of Evil but the title page has both titles.
