FROM THE BESTSELLING AUTHOR OF THE ADVERSARY. One morning, a man shaves off his long-worn moustache, hoping to amuse his wife and friends.

But when nobody notices, or pretends not to have noticed, what started out as a simple trick turns to terror.

As doubt and denial bristle, and every aspect of his life threatens to topple into madness—a disturbing solution comes into view, taking us on a dramatic flight across the world.
