Purgatory : a Jack Taylor novel
(Book)

Recovering from the mental and physical wounds inflicted from his recent past, former cop Jack Taylor has finally found a modicum of peace. Yet this fragile existence is threatened when a vigilante killer begins targeting citizens, signing mysterious notes with the moniker 'C 33.' The killer addresses these letters to Jack, trying to persuade the volatile ex-cop to help cleanse the scum of Galway. While Jack tries to unravel the mystery, he is also brought into the fold of an enigmatic tech billionaire who has been buying up massive amounts of property in Galway. If Jack has learned one thing, it's that people who outwardly claim to be on the side of righteousness are likely harboring far more nefarious motives beneath the surface. With the help of his friends, former drug dealer turned Zen master Stewart and dogged police sergeant Ridge, Jack is determined to track down C 33.
