Three paths converging on Cologne at Carnival at a time when the world is traditionally turned on its head and Chaos rules. And everybody hides behind a mask. Fabel finds himself on a trail of betrayal and vengeance, violence and death. And once more faces his greatest enemy: the true Master of the Carnival.
