Nick glanced at the door, to be sure that he had closed it. He then replied more impressively:

“I am a stranger to you, Mr. Paulding, but you will make no mistake in meeting me halfway and taking my advice. I frequently am a good friend to have in time of trouble.”

“I know of none I would rather have,” Paulding said quickly.

“That goes, does it?”

“You bet it goes.”

“What now passes between us, then, must be strictly confidential,” said the detective. “You must, moreover, be governed by my instructions. You will presently see, I think, that that will be the only wise course for you to shape. If you are not inclined to meet me in this way——”

“But I am,” Paulding cut in earnestly. “I’m not blind. I now see there is something wrong, Mr. Carter, and that you are here in my behalf. I would be more than a fool, sir, if I did not take advantage of your offer. I promise in advance to do what you direct.”

“Very good,” Nick said approvingly. “You will not regret it.”

“But how am I in wrong?” Paulding asked anxiously. “Has a crime been committed? Was Todd murdered?”

“I think so,” said the detective.
