"The rich man again," laughed Bob, but Heinrich said nothing. "Any trace of Percy?" Bob inquired. "No," said Heinrich sorrowfully. "I guess he iss gone." "We've just been talking to Karl Hoffmann," said Bob. "You don't suppose he could have stolen him, do you?" Immediately Heinrich's manner changed. He rose to his feet angrily, while Bob nudged Hugh. Heinrich became pale with rage. "That scoundrel!" he stammered. "I would not be surprised if he would steal poor Percy. He iss mean and low enough to do anything." "Why, Heinie," said Bob mildly. "I always thought Karl was a fine fellow." "He iss a low down snake!" cried Heinrich. "I would not trust that fellow mit two cents." "Lena likes him," said Bob. Heinrich became madder than before at this remark. He stuttered with rage, and advancing toward Bob shook his clenched fist in his face. "Sure she like him," he cried. "Why not? He gives her presents all the time and it iss for that that she like him. She knows what a low down cur he iss, for I have told her so. Only because he has money and can give her presents does she like him. But I will show her!" "What are you going to do?" demanded Bob, somewhat alarmed by the violence of Heinrich's manner. "I buy her presents now," exclaimed Heinrich. "You see that?" he demanded, pulling the roll of bills out of his pocket. "You see that?" he repeated. "Well, I got some money now, and I show her who can buy nice presents. She like me better than Hoffmann when I get more money than he." Heinrich looked at the bills held in his fist, and then jammed them back fiercely into his pocket. "Where'd you get all the money?" asked Bob. "You didn't draw it out of the savings bank, did you?" "No," exclaimed Heinrich. "I earn it." "Working for father?" "No, for Mr. Wernberg." "What!" exclaimed Bob, completely taken by surprise. He and Hugh looked at each other in astonishment. This was a new turn of events. "Yes," said Heinrich. "I do some work for Mr. Wernberg; he iss a fine man too." "What was the work?" inquired Bob. He remembered that Hugh had advised him to watch their chauffeur. He never imagined, however, that even if Heinrich was guilty he would be so bold as to confess brazenly that he was employed by a man to plot against the United States. Still, he had always suspected that poor Heinrich was not quite right in his head. "I cannot say," said Heinrich. "The work iss secret." "Why, Heinie," exclaimed Bob. "I never thought you would do a thing like that." "Why not?" demanded Heinrich. "I do my work here, don't I? Why should I not make a little extra money if I can?" "But Mr. Wernberg is a bad man." "He iss not," Heinrich protested stoutly. "He iss one man who knows right from wrong."
