Aberystwyth is a real city of sins. An underground chain selling blankets for dummies, dens with glazed apples, a joke shop with black soap and a steam railway with real ghosts, an ice cream den run by a retired philosopher, and the Snail Tray - all the losers flock to it... The Druids control everything in the city: Bronzini - ice cream, tailors and hairdressers, Llewellyn - crazy golf, apples and lotto. But we know who controls the Druids themselves, don't we? Not so. In a city ruled by a Welsh language teacher and a school PE teacher, someone is killing schoolchildren who copied an essay about the legendary Celtic land of Cantrev y Guaelod, and someone else is building a real Ark in the stadium. Private detective Louis Knight and his assistant Amba Polundra are on the trail of the mysterious Guenno Guevara, a veteran of the Patagonian War - they must prevent the apocalypse... Aberystwyth, my love... You would never have guessed that the Celts could be like this.
