The Vulgar Boatman - William G. Tapply

When a politician's son is suspected of murder, Boston lawyer Brady Coyne is dispatched to fix it—only to uncover a web of deceit: "Tapply at his best" (The New York Times).
Running for governor on the Republican ticket, Tom Baron needs his image to be squeaky clean. He employs men like Brady Coyne, a compassionate Boston attorney, to keep problems far away from his campaign. But when his son doesn't come home one night, Tom's political strategy becomes a criminal matter.
His son's girlfriend has been murdered, and the boy has no alibi. To protect his friend's political ambitions, Brady digs into the investigation, finding a trail of drugs and corruption that stretches far across the Eastern seaboard.
Tom Baron may be his friend, but Brady Coyne will stomach no cover-up. If the son is guilty and Tom is involved, Brady will come down on the would-be governor with a fury that will make Boston politics look like a student council election.
