Bob shook his head sorrowfully. It hurt him to discover that their chauffeur, a man he had grown up with and liked, was working hand in glove with Mr. Wernberg. He never would have believed it possible had he not heard it with his own ears from Heinrich himself. It was a great shock to him and he knew how badly his father and mother would feel. Of course he must tell his father. CHAPTER XIX A DISCUSSION "Come on, Hugh, let's go," exclaimed Bob. Heinrich had turned away from them and walked off angrily. The combination of Lena and Karl and Mr. Wernberg, had been too much for him to stand apparently. He was mad clear through. "Well," said Bob, when they were outside, "I never would have believed that." "I told you to watch them all," Hugh reminded him. "I know you did, and I guess you were right. Why poor old Heinie should be such a fool is more than I can understand." "Are you going to tell your father?" "I suppose I must." "Will he tell the police?" "I don't know. I should think perhaps he'd have to, though." "It's too bad," murmured Hugh. He knew how fond his friend was of Heinrich. "At any rate Karl is all right I guess," said Bob. "I'll agree with you there," said Hugh. "How about Lena?" "Don't ask me. I feel as if I couldn't think." Mr. Cook met them on the front porch and was at once impressed by the expression on the faces of the two boys. "What's wrong?" he demanded. "We've just had an awful shock," said Hugh. "What is it? Tell me, Bob," his father urged. "Heinrich is one of Mr. Wernberg's gang." "Say that again," exclaimed Mr. Cook incredulously. "Heinrich is working with Mr. Wernberg. You ought to see the pile of money he has been paid already." "Why, Bob," exclaimed Mr. Cook amazedly. "I think you must be mistaken." "He just told us himself," said Bob. "He said Mr. Wernberg was a fine man and one of the few who knew right from wrong." "How did he happen to tell you all this?" Bob related the circumstances to his father. When he had finished Mr. Cook remained silent for several minutes. "I am so sorry," he said finally. "I don't see why Heinrich told you." "He was mad," said Bob, "and jealous." "A dangerous man to hire for that kind of work I should think," exclaimed Mr. Cook. "If he would say as much as he did to you this afternoon I don't see what there is to prevent him from telling all he knows." "You mean he might give the whole thing away?" "Exactly." "Still," said Bob, "Heinie can be awfully stubborn sometimes." "I know it. We'd have to be clever to get a full confession from him I imagine." "I don't see what use he could be to Mr. Wernberg," said Hugh. "It's a favorite method of these German plotters, Hugh," said Mr. Cook. "Very often they get some simple-minded, ignorant fellow like Heinrich and make a tool of him. Heinrich hasn't got brains enough to think of anything himself." "Are you going to turn him over to the police?" inquired Bob.
