“This rope has been cut with a sharp knife.”

Nick joined him, and, looking at the end, agreed with the officer, while both wondered why it had been cut.

“Do you know who lives here?” asked Nick.

“Yes; the man’s name is Jacob Herron.”

“What is he?”

“A Wall Street man.”

“A broker or banker?”

“I don’t know what he is. A sort of speculator, I guess. Anyhow, he’s a pretty big man.”

“Well,” said Nick, “we ought to arouse the family and make an investigation.”

The two went to the front door, where the officer rang the bell several times without securing a response.
