A killer targets the royal family of a small European principality insured by Lime Street. To protect the last heir, Christina, Grey brings her to his US farm, but the assassin pursues them.

Remember D.B. Cooper, the sky-jacker who parachuted out of a plane with an enormous ransom? Here's a variation on that theme and J.G. has to find the man and the money if his Lime Street operation is to survive.

How does a gigantic steam disappear? That's the quest J.G. and Wingate must answer when they are called in to investigate the "theft" of a historic English train. Filmed in the lush countryside of England, J.G. in his inimitable style and grace, divides his time playing detective and father when his two daughters have trouble getting along.
