"I haven't any, General Crandall," the other replied, with a faint smile, "or your Indian, Jaimihr Khan, would have placed them in your hands after the search of my room yesterday. I've convinced Major Bishop of my genuineness, however--after we left your house and when the moment for action arrived. A cable to Sir Ludlow-Service, in the Downing Street office, will confirm my story. Meanwhile I am willing to go under arrest if you think best." "But--but I don't understand, Captain--er--Cavendish. You posed as a German--as an Englishman." "Briefly, General, a girl secretly in the pay of the Downing Street office--Louisa Schmidt,--Josepha, the cigar girl, whom you ordered locked up a few hours ago--is the English representative in the Wilhelmstrasse at Berlin. She learned of a plan to get a German spy in your signal tower a month before war was declared, reported it to London, and I was summoned from Khartum to London to play the part of the German spy. At Berlin, where she had gone from your own town of Gibraltar to meet me, she arranged to procure me a number in the Wilhelmstrasse through the agency of a dupe named Capper----" "Capper! Good Lord!" Crandall stammered. "With the number I hurried to Alexandria. Woodhouse--Captain Woodhouse, from Wady Halfa--a victim, poor chap, to the necessities of our plan, fell into the hands of the Wilhelmstrasse men there, and I gained possession of his papers. The Germans started him in a robber caravan of Bedouins for the desert, but I provided against his getting far before being rescued, and the German agents there were all rounded up the day I sailed as Woodhouse." "And you came here to save Gibraltar--and the fleet from German spies?" Crandall put the question dazedly. "There were only two, General--Almer and your servant, Jaimihr. We have them now. You may order the release of Louisa Schmidt." "The captain has overlooked one other--the most dangerous one of all, General Crandall." Jane stepped up to where the governor stood and threw back her hands with an air of submission. "Her name is Jane Gerson, of New York, and she knew all along that this gentleman was deceiving you--she had met him, in fact, three weeks before on a railroad train in France." The startled eyes of Gibraltar's master looked first at the set features of the man, then to the girl's flushed face. Little lines of humor crinkled about the corners of his mouth. "Captain Cavendish--or Woodhouse, make this girl a prisoner--your prisoner, sir!" [Illustration: "Your prisoner, sir."] CHAPTER XIX AT THE QUAY Five o'clock at the quay, and already the new day was being made raucous by the bustle of departure--shouts of porters, tenders' jangling engine bells, thump of trunks dropped down skidways, lamentations of voyagers vainly hunting baggage mislaid. Out in the stream the _Saxonia_--a clean white ship, veritable ark of refuge for pious Americans escaping the deluge.
