"This iss terrible," repeated Heinrich. "What will they do mitout me?"
"Who?"
"My friends."
"It's too bad," said Bob, more convinced every moment that mischief was afoot that evening. "I don't know what you can do about it though."
"Of course I have to go mit your father," said Heinrich finally, heaving a great sigh. "I wonder if he will want the car for long."
"I think he will."
"Very well," said Heinrich, becoming resigned to his fate, "I will be there but only because I do not wish to lose my job. But I fear something will happen."
"That's just what we want to prevent," thought Bob grimly. "All right then, Heinie," he said aloud. "Father will expect you in half an hour."
He hurried back to the house, warned his father that he should keep Heinrich always within sight, and related his conversation with the chauffeur as an argument for this course. Then he went upstairs, two steps at a time to make ready his disguise. While he was there Hugh arrived and went up to Bob's room.
"What are you doing, Bob?" he demanded.
