The Big Kill [abridged]

The rain clawed at the windows of the bar.  Hammer was angry and wanted to be left alone.  But when he sees a desperate guy abandon his kid in a bar just to step outside and get blown away, Hammer's mood switches from bad to worse.  By the time he reaches the dead body, he knows he will have to pound his way through a world of thugs and wiseguys to find out how a reformed ex-con got desperate enough to die like that.  What Hammer doesn't know is how a beautiful woman will figure in--and how many bullets justice will take.
