Third and final part of the Dickson McCunn trilogy, where he and the usual sidekicks fall into a plot involving an exiled prince's attempt to regain the throne despite the efforts of bad guys to keep him from it. The novel is set in the fictional Central European country of Evallonia in the early 1930s. It concerns the involvement of some Scottish visitors in the overthrow of a corrupt republic and the restoration of the monarchy. It is a sequel to Castle Gay, in which some Evallonians visited Scotland on a secret mission two years before the start of this novel. The three McCunn books are best read in order as there are a number of references to events that happened in previous books. This book chronicles the methodology of a bloodless patriotic coup that might be helpful today around the world!
