Alexander Jessiersky, Austrian aristocrat and shipping magnate, finds the Nazis distasteful - but in war and in business, distaste can lead to negligence. When Jessiersky's board of directors sends his mysterious neighbour Count Luna to a concentration camp on trumped-up charges in order to seize his land, Jessiersky can't shake the feeling that Count Luna blames him - and, after the war ends, that Count Luna will have his revenge.

So begins a wild, weird and witty cat-and-mouse chase through windswept moors, shadow-filled houses and, eventually, the catacombs of Rome, as an increasingly paranoid Jessiersky asks himself: who is Count Luna? Where is he hiding? And will he stop at nothing - not even the edges of the plausible and canny - to exact his bloody venegance?
