A highly exciting adventure story featuring James Schuyler Grim, better known as Jimgrim. Jimgrim is an American secret service agent employed by the British and stationed in Jerusalem. With
him are his faithful sikh shadow, an American and an ex-soldier of the Australian forces, all eager for a fight of any kind. This opportunity soon presents itself, as the ambitions of the
French in Syria arouse the enmity of King Feisal of the Arabs. For his aid in WWI, the Allies promised Feisal the kingship of Syria, Palestine and Trans-Jordania. This promise they have not
kept, however, and the French are out to discredit or kill the Arab chieftain. To further their ends, an order is forged, ostensibly from Feisal to his Arab adherents, which calls for a
massacre of the Jews in Jerusalem.
