This last, listed in his book as "Special Agent A. S.," was Otto F. Mottola, a detective in the warrant squad. The notebook revealed Mottola as "Antonio Marino," an alias later changed to Antonio Salvatore. Evidence was produced at Mottola's trial at Police Headquarters that Koenig paid him for investigating a passenger who sailed on the _Bergensfjord_; that he often called up Mottola, asked questions, and received answers which Koenig's stenographer took down in shorthand. Through him Koenig sought to keep closely informed of developments at Police Headquarters in the inquiry being made by the police into the activities of the Germans. Mottola was dismissed from the force because of false statements made to his superiors when they questioned him about Koenig. Koenig's very caution was the cause of his undoing. The detectives who shadowed him learned that he "never employed the same man more than once," which meant simply that he was careful to place no subordinate in a position where blackmail and exposure might be too easy. To this fact they added another trifling observation; they noticed that as time went on he was seen less in the company of one George Fuchs, a relative with whom he had been intimate early in the war. They cultivated the young man's acquaintance to the extent that he finally burst out with a recitation of his grievances against Koenig, and betrayed him to the authorities. "P. K." was defiant always. "They did get Dr. Albert's portfolio," he said one day, "but they won't get mine. I won't carry one." CHAPTER VII FALSE PASSPORTS Hans von Wedell's bureau--The traffic in false passports--Carl Ruroede--Methods of forgery--Adams' coup--Von Wedell's letter to von Bernstorff--Stegler--Lody--Berlin counterfeits American passports--Von Breechow. Throughout August, 1914, it was comparatively easy for Germans in America who wished to respond to the call of the Fatherland to leave American shores. A number of circumstances tended swiftly to make it more hazardous. The British were in no mind to permit an influx of reservists to Germany while they could blockade Germany. The cordon tightened, and soon every merchant ship was stopped at sea by a British patrol and searched for German suspects. German spies here took refuge in the protection afforded by an American passport. False passports were issued by the State Department in considerable quantities during the early weeks of war--issued unwittingly, of course, for the applicant in most cases underwent no more than the customary peace-time examination.
