Purgatory

Someone is scraping the scum off the streets of Galway, and they want Jack Taylor to get involved. A drug pusher, a rapist, a loan shark are all targeted in what look like vigilante attacks. And the killer is writing to Jack, signing their name: C-33. Jack has had enough. He doesn't need the money, and doesn't want to get involved. But when his friend Stewart gets drawn in, it seems he isn't been given a choice.
