"What's the matter, Mrs. Mack?" asked Mark.

"This man is going to rob me," answered the old woman. "Oh, save me!"

"It's a lie!" said Jack Minton. "Just ask this woman who I am. She knows."

"Who is he, Mrs. Mack?"

"It is my nephew, Jack Minton. He——"

"Do you hear that? I'm her nephew, come in to make her a call after a long time."

"What are you doing to her?" demanded Mark suspiciously.

"Trying to stop her infernal racket. You'd think I was murdering her by the way she goes on."

"What made you scream, Mrs. Mack?"

"Because he—he was going to rob me."
