"_Auf weidersehen_, Von Rintelen." Von Bernstorff held out his hand. Von Rintelen bowed and shook the hand of each of the men with whom he had been associated and with hurried expressions of farewell, left the room to make preparations for flight from the country, flight that ended for him at Falmouth, England, where he was detained and returned to New York City. In February, 1918, Judge Howe of Vermont sentenced him to imprisonment for his activities against the peace of the United States. After Von Rintelen's exit, Von Bernstorff turned once more to his fiscal spy and Boy-Ed and Von Papen. "As I said, we who are left must concern ourselves with the necessities of the moment which seem to be pressing upon us. Dr. Albert, what was the most important paper in the portfolio you carried?" "Von Rintelen's report of the bombs placed on sugar ships." Von Bernstorff smiled slightly. "That may give us a clue! Are all the ships at sea?" "Yes." "Then if the papers are in the hands of the Secret Service----" "They'll wireless the ships at sea," broke in Albert. "Exactly." Bernstorff nodded matter-of-factly. "We can find out speedily if they're in possession of our secrets and arrange our acts accordingly. You, Von Papen, and Boy-Ed, get out the Long Island automobile wireless and catch any messages that Sayville may send out tonight. Where is Von Lertz?" Von Papen shook his head. "I think he has an engagement with Miss Mason." "Miss Mason? Who is she?" Von Bernstorff glanced up sharply, but without waiting for reply went on, "he will have to break it. He must help you. I will telephone him to get Wolff von Igel and help you." Von Papen and Boy-Ed, bowing, left the room. Bernstorff caught up the desk 'phone and rattled the hook impatiently. He was answered in a moment, and as he gave the number of Von Lertz's apartment, the girl at the switchboard smiled to herself in the privacy of her corner, and made a double connection for the benefit of Dixie Mason, who had been careful to plant her operatives in strategic places. Dixie Mason, listening quietly, on the 'phone in her own little boudoir heard Bernstorff call for Heinric von Lertz, and in a moment caught Von Lertz's quiet answer. She heard Bernstorff's explanation of his call and the story of the loss of the reports given in a few words. "There is no time to waste, Von Lertz. All messages must be caught. Get Wolff von Igel at once, and you two go out with Von Papen and Boy-Ed in the machine." "I will be with them in three quarters of an hour or sooner, if I can make it," Von Lertz answered somewhat slowly. Dixie smiled broadly and suppressed a girlish giggle. The reason for Von Lertz's hesitancy was not hard to be guessed at.
