John Hamilton, 1933.
Early printing most probably 1933. Colour frontispiece & four b&w illustrations. 256pp with no rear catologue. Blue boards with red titles [first printing gold titles] & sundial device to spine. A very good+ copy with clean boards & no chipping, nicking or tearing to cloth. Internally clean with no inscriptions. Very light spotting to front pastedown. This edition has been published with the "Other titles in the Ace Series" page as the front pastedown and no front blank or halftitle - possibly a manufacturing fault but all appears as originally manufactured and no counter page missing later in the book from lack of halftitle which there would be. An elusive early title.
The second Biggles title with the action taking place mainly in South America during the interwar years.
