Cologne Infernal

For centuries, a deadly secret has lain hidden within Cologne Cathedral.   When a cryptic medieval message is discovered during the construction of the new tower entrance, events spiral out of control — right at the start of street carnival in 2009.   Young American symbologist Claire and her Cologne friend Gereon are thrust into a breathless chase through the old city. An ancient threat awakens, and suddenly not only the cathedral, but the entire city of Cologne stands on the brink of disaster.   Full of local color, black humor, and historical depth — a thriller that reveals a side of Cologne you'd rather not know.
