Das Königsprojekt
Carl Amery
 The Vatican gains possession of a time machine from Leonardo da Vinci after the inventor's death. Selected members of the Pope's Swiss Guard are sent back in time to alter history in favour of the Catholic Church. All this is supervised by a very small group of church officials and without the specific knowledge of the current Pope. The Vatican learns that major historical events can't be prevented, only their details can be altered. For example, the Reformation can not be undone, but the details surrounding it can be changed: Martin Luther can't be killed before publishing The Ninety-Five Theses, but the failed attempt on his life by a time-traveling agent is interpreted by Luther as a visitation by the devil. In 1688, the Progetto Reale (English: Royal Project) is undertaken by the men in charge of the department. The project's aim is to reestablish Catholicism in England through restoration of the House of Stuart. The Catholic Church perceives the Stuarts as too weak for their purposes and instead selects the Bavarian House of Wittelsbach as an alternative. For the purpose of legalising the claim to the British throne, a member of the Swiss Guard, Arnold Füßli, is sent out to exchange the Stone of Scone for a fake. While this mission succeeds, the stone is deposited at what later becomes a reservoir and is lost for the cause. The Church's main asset, its loyal Swiss Guard soldier Franz Defunderoll, however, chooses to desert and meet his unsuspecting self in the future. Eventually, the time machine is destroyed. In the finale of the book, the rebellious Bavarian-Scottish troops sacrifice themselves in the reservoir attempting to recover the Stone.
