"We think so. I still don't see what that has to do with Heinie." "How do you know Heinrich wasn't here?" asked Hugh. "You mean that Heinrich is a plotter?" exclaimed Bob, suddenly realizing what his friend was driving at. "He might bear watching," said Hugh. "He and that German cook of yours." "They're both honest and reliable," exclaimed Bob warmly. "Well," said Hugh, "I heard a story last night about two men coming to a house where they had a nice 'honest and reliable' German girl and demanding to see her. The owner of the house refused, and the men then showed secret service badges. Of course when he saw the badges he had to do as they said and he called in the girl. As soon as she came into the room one of the men went up to her and grabbed hold of her hair. Well, sir, it came right off her head and then they discovered that the maid was nothing more nor less than a man, a German in disguise, trying to get information for his government." "Is that a true story?" exclaimed Bob in amazement. "The man in whose house it happened told it to father," said Hugh. "It only goes to show that you can't be too careful. I wouldn't be too sure about Heinrich and Lena if I were you. The Germans are a bad lot and I suspect them all." "Perhaps," said Bob. "Still Heinie and Lena are different." "They may be tools of Mr. Wernberg for all you know." "You're foolish," exclaimed Bob. "Why even if they weren't loyal to the United States they'd be loyal to father and mother. I know that." Hugh shrugged his shoulders. "It sounds fishy to me, that's all," he said. "Didn't Heinrich say he went to a party last night? How do you know the party wasn't held out here, and that he just happened to run across your car and decided to bring it home." "If he had he would have washed the car last night, not this morning." "Why so?" "Because he's so methodical, like all the Germans. He never could have slept if he had known the car was dirty." "Why, Bob," Hugh protested, "Heinrich says he didn't come in until twelve o'clock and he says the car was there then. Why didn't he notice that it was dirty then? I'd like to know." "He probably didn't light but one light in the garage and didn't notice it." "Sounds likely," snorted Hugh. "Take my advice and watch 'em both." "They're just as faithful as you or I," exclaimed Bob. "You can't talk me into getting suspicious of those two." "The faithful ones are the ones to suspect," said Hugh grimly. "Nonsense," said Bob, but his friend's words nevertheless set him to thinking. What if Heinrich and Lena should turn out to be working in the interests of Germany? He recalled the light in Lena's room the night before, and then he thought of all the money Heinrich had had and how embarrassed and uneasy he had been when Bob spoke of it. Ugly stories of Germans crowded through his mind, but he refused to believe that their two servants were of that sort.
