MYSTERY:  Homicide cop Tom McMichael is on the rotation when an 84-year-old city patriarch named Pete Braga is found bludgeoned to death. Not good news, especially since the Irish McMichaels and Portuguese Bragas share a violent family history dating back three generations. Years ago Braga shot McMichael's grandfather in a dispute over a paycheck; soon thereafter Braga's son was severely beaten behind a waterfront bar - legend has it that it was an act of revenge by McMichael's father.

McMichael must put aside the old family blood feud, and find the truth about Pete Braga's death. Braga's beautiful nurse is a suspect - she says she stepped out for some firewood, but key evidence suggests otherwise. The investigation soon expands to include Braga's business, his family, the Catholic diocese, a multimillion dollar Indian casino, a prostitute, a cop, and, of course, the McMichael family.
