In this book, the California land developer and hotelier investigates the Jewish Question by characterizing Jews as 'cuttle-fish' "squirting their ink into clear water and rendering their prey helpless by circulating rumors and slinging slogans." Their prey is Gentiles ('Jelly-Fish', 'Poor-Fish' and 'Suckers') who they control as outlined in the Protocols through their manipulation of finance, which Stevenson traces back to Biblical times. A much more overtly anti-Semitic work than his previous book, "The Secrets of Plutology," Stevenson's views may have been influenced by the Depression when he lost most of his wealth.
