is the target of a not too smart gang of jewel thieves. The difficulty lies in the fact that the emerald is rarely seen except on the lovely neck of
Mrs. Jonathan Prescott, the wife of a multi-millionaire owner of a newspaper and broadcasting empire.
Billy and his "gang" have devised a plan to remove the emerald from
Mrs. Prescott's neck during an anniversary party attended by the elite of the city. Their success becomes more and more unlikely as one difficulty after another arises, but Billy pursues the plan to a surprising finale.
The Christine Emerald is a fun read reminiscent of stories told during the Roaring Twenties.
