About the Book: The most closely guarded secret in the world is about to be exposed. Harvard Professor Richard Wangley is enjoying a relaxing visit to Prague—the city of magic and labyrinthine tunnels—when his girlfriend suddenly vanishes just hours before publishing an earth-shaking manifesto. When a series of hideous murders points directly to him, Wangley is forced to go on the run to prove his innocence and prevent a catastrophic global threat. Far from home and armed only with his wits, his knowledge of ancient symbolism, and a cream turtleneck, Wangley must navigate a city where every cobblestone holds a clue or a trip hazard. As a grotesque spectre closes in, he races against time, lost in a dangerous labyrinth far more complex than any he has encountered before
