Eh
I just didn't get it.
Here we have the story of Dermot. He lives in the New York area, his father skipped out when he was a kid and he grew up to be a shady cop. He takes kickbacks and bribes, hustles hookers on the job, has a mistress and is drinks a lot. But he only drinks when he is out, his mom drinks at home, that makes her a drunk. He also basically ignores his kids because, reasons.
He is brought up on charges for assaulting a transvestite prostitute and as a way to get in with the board he goes to the homeland, Ireland. His intention is to see his father for the first time in decades. Eventually he meets his father again for the first time, there is no teary eyed reunion, he is treated as little more than another drinker at the bar.
While there he falls in love with a fiery socialist organizer while living in the squalor of what was Catholic Ireland at the time. He is constantly trying to nail this lady and she is always telling him yes, but not now. In the meantime he is with her for riots and political rallys, he sees how awful the conditions are for the Catholics in the area, who are under the thumb of the Protestants. Eventually, on the night of his lustful union with her is to commence, she stops off to lead another rally and she is shot in the head.
Dermot is troubled with the event and walks in a daze. He makes it back to New York and nothing changes. He still hangs out with the same low life cops, avoids his wife and drinks when he is out.
I am sure there is larger meaning here, something I am missing, but to me it doesn't matter. What we have here is the story of a sad, selfish, self destructive cop who has a traumatic experience and it does nothing for his life except for a brief feeling of otherness.
The section of the book before he gets on the plane and goes to Ireland is gripping and sad in the way that makes you feel, after that the Irish Squalor lessens the rest of the novel.
