"A nephew of the old lady."
"But what makes you think he is the guilty party?"
"He has once before visited Mrs. Mack, and tried to extort money from her."
"How do you know this?"
"Because I live in the same house with Mrs. Mack. She occupies the room directly over where my mother and myself live."
"Then you live in New York?"
"Yes, sir."
"How do you happen to be here?"
"I came on business for a New York jeweler."
"What is the name of the party you suspect?"
