“You have heard of him?”

“More than that. Seen him. He and another crook nearly waylaid me on the Drive.”

“You have the best of me. I never saw him. But I fancy the fellow has a record. Question is, what were the rascals about?

“And the other man,” he exclaimed quite abruptly, “was the man with a hole in his hand! He was the one who beat you up. Matters appear to have come to a head. We will put all these together and arrive at something.”

“And the bullet?” It was Newton Mills again.

“I was unable to learn anything. However, I cautioned them to save the bullet.”

“Good!” muttered Mills.

“We are driving to the city at once,” said Herman. “Shall you go with us? May I ask you to assist us in this case?”

Newton Mills’ slight form stiffened perceptibly. “I will gladly do all I can.”
