Fortunately I have still some time this evening to add the page with the letter A. The caption is ‘A-menaçant’ (Threatening A). The steel engraving on the left side of the page shows a man in what appears to be a dungeon, or tower, being threatened by the shadow of the letter A. The author, Bronowski, of whom we know nothing about, refers to a book he found, a bit like me, finding his book, which contains information about a threat to the human race, 123 years from ‘his’ present time. This might be an interesting read after all.
