Shaw and McGregor conduct the most crucial interrogation of their FBI careers: on Paul Carna-han, or whatever it is that lurks inside him. He tells them a tale of unimaginable, unequaled de-pravity-but his horrifying life story may provide the clues the two agents need to make sense of their grim surroundings.

A new kind of horror story for modern America, written by Garth Ennis (Preacher, The Boys, Crossed) and drawn by Goran Sud uka (Y: The Last Man, Hellblazer)
