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.
