"Ah; about that ring, my dear guest. Do you think a hundred and fifty thousand lira too much for it?"

"You said a hundred thousand."

"That was this morning, signore. The ring has increased in value since. To-morrow, without doubt, it will be worth two hundred thousand."

Tato laughed at the rueful expression on the victim's face, and, a moment after, Uncle John joined in his laughter.

"Very good, duke," he said. "I don't wish to rob you. Let us wait until to-morrow."

The brigand seemed puzzled.

"May I ask why, Signor Merreek—since you are warned?" he enquired.

"Why, it's this way, Duke. I'm just a simple, common-place American, and have lived a rather stupid existence for some time. We have no brigands at home, nor any hidden valleys or protected criminals like yourself. The romance of my surroundings interests me; your methods are unique and worth studying; if I am so rich as you think me a few extra hundred thousand lira will be a cheap price to pay for this experience. Is it not so?"

The Duke frowned.

"Do you play with me?" he asked, menacingly.
