Not one of Hubbard's best, but a fun pulp adventure from the December, 1936 issue of Five Novels Monthly magazine. The characters aren't as fully developed as they could have been... we never learn why the American Lieutenant is in the French Foreign Legion, for example... but the straight-forward plots zips along, and the descriptions of the setting are well rendered. The original interior illustrations are included, as Galaxy Press always does with their handsome uniform editions, but for some reason they stuck a somewhat random cover from Argosy magazine on the cover of this one.
