Manslaughter (Stanley Hastings Mystery #15)

Stanley takes on the case of Joe Balfour--who did time for killing a man in a barroom brawl and is now being blackmailed--and winds up breaking and entering, contaminating crime scenes, concealing evidence (or else planting it), framing two innocent men for two different homicides, aiding an extortionist, hanging out in a topless bar, blackmailing a few attorneys, and outwitting the cops.
