Used. Mass Market Paperback. Brad Meltzer boldly bridges biblical antiquity and comic book lore by connecting the first murder weapon with the genesis of Superman. When a contemporary shooting drags a reluctant hero named Cal Harper into a perilous pursuit across Florida, he uncovers a chilling connection between a century-old homicide and the mark of Cain. It is a smartly paced thriller that will have you flying through the pages faster than a speeding bullet.
