A specific one, that is. Set mainly in New York, the protagonist is an ex-alcoholic ex-cop who put away a psychopath some years before. The criminal vowed to kill every woman who meant something to our hard-boiled hero. He ended up serving more than his sentence (for bad behaviour), but is now out, and seething for revenge. He is characterized by having very strong fingers, which he uses to attack pressure points when fighting.
Memorable incident: our gritty ex-cop buys a bottle of bourbon, and then pours it down the sink. He then calls his AA sponsor, who tells his how stupid that was.
Memorable aphorism: for various reasons (given, but I've forgotten them), cops and hookers make for good couples.
Memorable (but probably misremembered) quote: "He still had strong fingers, the strongest I've ever known. And he still had a glass jaw."
It's been a few years since I read it, so it can't be all that hot off the presses.
Any of the above information may be inaccurate, or just flat out wrong. Good luck, and many thanks to anyone who can help!
