How far would you go for revenge? If you were given a chance at deadly retribution with a guarantee that the law could not touch you, would you take it?Thats the opportunity that a man called Agent Graves provides, in the form of a special briefcase containing an untraceable gun and one hundred rounds of ammunition. To the damaged and downtrodden living on the fringes of society, the offer is a once-in-a-lifetime chance to even their scores. But beyond the dilemma of whether or not to pull the trigger lies a deeper and even more troubling concern: just who is making these actions possible and why?This second of five volumes reprinting all 100 issues of writer Brian Azzarello and artist Eduardo Rissos 100 BULLETS collects issues #20-36 of their acclaimed Vertigo series.
