Treece, Henry — Jason, 1963, Four Square, paperback, 336pp., novel (set in Mycenaean Greece, based on legendary characters), first p/b edition.

N.B. In the early 1980s, Savoy planned to publish a series of books by Henry Treece (in addition to their ‘Celtic’ tetralogy volumes [1980]). For a variety of reasons, this never happened. So Jayde Design is listing a number of those (and other) titles, of which this is one.
