The Suicide Murders (Howard Engel)

This is a pretty typical example of the hardboiled detective story. Benny Cooperman is in his office when a beautiful woman brings him a job - she thinks her husband is having an affair. Cooperman agrees to look into it and starts following the husband, but then the next thing he knows the husband is dead of an apparent suicide. He's not convinced, though, and continues to dig into what he is more and more convinced is murder, and along the way uncovers more suspicious "suicides" that prove to be murders in disguise. Most of the typical tropes are here: an ambivalent relationship with police, corrupt politicians, getting waylaid by thugs, and being suspected of a crime himself. I definitely enjoyed the story enough to stick with it and learn how it ended, but have to say that I found it vaguely disappointing, especially when Cooperman made some pretty stupid decisions. No great enthusiasm here, but also no real aversion.
