“That will be satisfactory,” said Mr. Montgomery, promptly.

“Shall I give you a check for the amount?” asked the jeweler.

“I should prefer the money, as I am a stranger in the city, and not known at the banks.”

“I can make the check payable to bearer, and then you will have no difficulty in getting it cashed.”

While this conversation was going on, the clerk entered the store with the policeman, but Mr. Montgomery's back was turned, and he was not aware of the fact till the officer tapped him on the shoulder, saying: “You are my prisoner.”

“What does this mean? There is some mistake,” said the adventurer, wheeling round with a start.

“No mistake at all. You must come with me.”

“What have I done? You take me for some one else.”

“You have stolen a diamond ring.”

“Who says so?” demanded the adventurer, boldly. “It is true I brought one here to sell, but it has belonged to me for years.”
