“You came up here to consult with some doctors upon a case that is puzzling them, did you not?”

“Not at all! Not at all!” cried the other. “I am on one vacation. I am in no mood to consult mit dese country doctors. Ach! For why should I work when it is a vacation I need?”

“But think of the sick man!” cried Tom almost angrily. “Suppose he needs you?”

“I do not know that. I know nothing about it yet. Why should I consider him?” and the scientist shrugged his shoulders. “What is he to me?”

“He’s a good deal to me,” declared Tom Swift sternly. “You must pay me for helping you out last night by seeing this man—Mr. Nestor.”

“Not so! Not so!” cried Dr. Raddiker, his eyes flashing behind his huge spectacles. “Ach! You are like one of these American bandits—yes? You say you will take what you want if I will not give it cheerfully, yes? Ach!”

“That is the only way you can pay your bill,” declared Tom.

“Then the bill, it goes unpaid,” Raddiker almost snarled at him. To the driver of the car he added: “Go on! I haf enough of this town. I never want to see it again.”

The querulous, nervous, excited savant was doubtless an unhappy soul, and he liked to make other people unhappy. He turned about as the car started and cried:

“Gif my regards to the young lady. She was very nice and friendly yet. She is the only nice person I meet since I come from New York.”
