"So Jimmie is on the case too," laughed Frank. "Well, son, there's money in it for the man who restores my emerald necklace, which I'm sure to get back, in the end. Why, that necklace has been stolen about a thousand times, and has always been restored to the rightful owner. Once it was found in the heart of Africa, in the kinky hair of a native. There's blood on it, too, for men have been killed trying to steal it, and trying to prevent its being stolen. It's the most valuable necklace in the world."
