"You're to come up," he said.

Mark followed him up the staircase and into a back room. It was scantily furnished. There was a lounge on one side of the room, and a cabinet bed on the other. These, with three chairs and a bureau, constituted the furniture.

"Just step in here," said the boy, "and I'll call Mrs. Montgomery."

Mark took a seat on the sofa and awaited the arrival of the lady.

He did not have long to wait. The door opened, but the lady he expected did not appear. Instead, a young man entered whom Mark instantly recognized as the person who had left the Fifth Avenue stage under suspicious circumstances on the day when the old lady was robbed of her pocketbook.

Mark started and wondered if the recognition was mutual. It did not appear to be.

"You're the jeweler's boy, I believe?" said the newcomer languidly.

"I came from Henry Swan."

"Exactly, and you have brought two diamond rings with you?"

"Yes."
