Le Grand Duc
René Goscinny
 A Russian grand duke pays a diplomatic visit to the United States, but in order for an important treaty to be completed, he first wants to have a recreational trip through the West, complete with bandits and Indian attacks! Lucky Luke is assigned as a bodyguard to the duke, who is quickly targeted by all sorts of villainous persons - first and foremost a Russian spy who tries his best (or worst) to assassinate the grand duke.
