British paperback publisher Sphere Books, founded in London in 1961 ambitiously undertook in 1968 the publication of the San-Antonio series. By that time, 70 novels pertaining to this Series had already been published in their original French. Their titles are listed, together with an English translation in the frontmatter pages of the Sphere books. The reader’s curiosity was triggered, but never satisfied. Only a few of the corresponding texts were to be translated. Titles such as San-Antonio in the groove or Action all the way and Swim or sink, San-Antonio never were. Sphere only published seven San-Antonio, and gave up on the project by the end of 1969. What remains are titles without books, a library left incomplete. A vacant lot of titles, a literary ghost estate.
