Hush money - Robert B. Parker

Spenser and his buddy Hawk are helping a couple of troubled friends. The first case involves the denial of tenure for Professor Robinson Nevins. While tenure meetings are always closed-door affairs, Nevins assumes that the recent suicide of graduate student Prentice Lamont (who some claim was having an affair with Nevins) ruined his chances for a coveted permanent position. Spenser and Hawk cut a brawl-strewn path through the members of the tenure committee on their way to the surprising truth of the Nevins case.
