His Royal Slyness

Thermosa, the Isle of Roquefort and Razzamatazz are neighboring kingdoms. The Prince of Razzamatazz is in America cavorting with Verona Vermuth when he receives word from his father via his tutor/bodyguard that Princess Florelle of Thermosa will be choosing the coveted role of her prince - either him or the Prince of Roquefort - and that he is to appear before the Royal Court of Thermosa immediately for such purpose. Not wanting to abandon the fun he is having in America, the Prince of Razzamatazz instead sends an American bookseller he meets to take his place at the Royal Court, as the two have a striking physical resemblance to each other; thus, the American could easily masquerade as the Prince. Although not very good at selling books, the American has no shortage of verve. That eagerness, unprincely in nature, causes one potentially disastrous international incident after another at the Royal Court. Matters are further complicated when the real Prince of Razzamatazz returns, and Princess Florelle makes her choice.
