Geistmann is a literary thriller. After a decade of futility, an Interpol task force recruits a research librarian, John Robinson, to join their efforts to catch the eponymous international perpetrator of everything from pranks, to cybercrime, to maimings, to murder. Now why would anyone (the head of the task force? the reader?) possibly believe a librarian could detect anything beyond a forged piece of incunabula? To find out, follow Robinson as, living dangerously, he follows Geistmann from Montreal to the southern Adirondacks, to Manhattan, to the Blue Ridge Mountains, to Navajoland, to France, and finally to Chisinau, Moldova. Hint: the short answer lies in the archives of the DGAFP, or Direction Générale de l'Administration et de la Fonction Publique, the agency which, since 1945, has provided personnel services for ENA, the École Nationale d'Administration, which is, in turn, the world-famous training school for France's political elite. Does this hint imply that all the mayhem was caused by some idiotic or malevolent bureaucrat? And what will Geistmann do to Robinson once he (who?) catches him (whom?).
