As children we're all told that there are no such thing as ghosts. However, when a former hitman for the IRA starts seeing the victims of his murders and seeking revenge for them, it doesn't much matter whether they're real or not because if he decides that someone is responsible for their demise, that person will get a chance to investigate the after-life first hand in the very near future. 
 Gerry Fegan was once a feared and respected killer for the Irish cause, but while serving a long stretch in prison, he started seeing twelve ghosts of people that he killed at the command of others. After getting out of jail, Fegan turns into a hard drinking loner who avoids his old IRA pals. With peace at hand and his old bosses now part of the new government, there isn't much demand for the services he used to provide any so they're content to pay him off and let him drink himself into oblivion. 
 When the ghosts start indicating that they want Fegan to kill off the people who had ordered their deaths, Fegan obeys in an attempt to finally get some peace. However, in the politically delicate climate, the murders of powerful former IRA leaders kicks off a new wave of violence and could derail the peace process. 
 I enjoyed this as a dark story about the consequences of murder and how some men use causes to further their own agendas. While some of the internal government stuff went over my head, I could usually figure out what the major players were scheming about. 
 My only complaint was that I found the story of Fegan turning into an instant protector for a young mother and her daughter who has gotten on the bad side of the old IRA leadership as being too quick and easy a way to make Fegan the 'good' guy in this story. I would have been more intrigued if it would have just stuck with him being a broken and damaged guy taking a twisted kind of revenge on behalf of people that he killed himself.
