100 Bullets Vol. 12: Dirty (100 Bullets)

This dark and intriguing Eisner Award-winning series features a mysterious agent named Graves who approaches ordinary citizens and gives them an opportunity to exact revenge on a person who has wronged them. Offering his clients an attaché case containing proof of the deed and a gun, he guarantees his “clients” full immunity for all of their actions, including murder.
In this volume, as more members of "The Trust" fall, one family head reaches out to a semi-retired Minuteman for help and protection. But with blood in the water and Graves and his soldiers making a final push for total control, will this old-timer be able to stop the massacre?
