Crow works as a hitman for the powerful Rome-based Tonio Family, operating out of Dublin in the criminal underworld of Ireland. His signature ability—the Gunslinger technique, which allows him to slow his perception of time and place shots with uncanny precision—came from his mother, a fortune-teller who was murdered before he was old enough to understand why. Taken in and raised by Papa Tonio himself, Crow was trained for violence by the seasoned Judas. Now he partners with Alice, a sharp young Englishwoman of German descent, in pursuit of the answers behind his mother's death—and those answers point directly back at the family that sheltered him.
