Remember The Darkness #1? Remember Joey "The Scar" Scarpaggio? No? Really? He was the mook that Jackie killed on the last evening before he became The Darkness! Well, it turns out he wasn't a mook at all!! In fact, he was an undercover FBI Agent! And if you thought the Mob takes care of its own, wait until you see what one renegade federal agent brings to bear on Jackie Estacado, and all the Darklings in Hell might not be enough to protect him!
