Two main storylines run through Book 4 of The Speedicut Papers ('Where Eagles Dare'): Speedicut's quest to identify the traitor within the British establishment, who has already occasioned him considerable personal problems, and his involuntary and often disastrous involvement in the geopolitical affairs of the Emperors of Austria, Mexico and the French and the future Emperor of Germany.

Speedicut's behind-the-scenes revelations in Book 4 shed a new light on the fall of the Mexican Empire, the Franco-Prussian War, the Paris Commune and a great deal more besides. There are such things as vampires ... and the records of the past, such as The Speedicut Papers, give proof enough for sane people.
