H Is for Homicide (Unabridged‪)‬

It started with the murder of Kinsey Millhone's sometime drinking buddy, an insurance claims adjuster. But before long Kinsey stumbles onto a massive insurance scam. Going undercover as a wisecracking vamp, Millhone descends into the Los Angeles nether world of machismo and gang hideouts. Her companion, terrified at having crossed the violent crook Raymond Maldonado, is Bibianna Diaz--no Girl Scout herself.

As the Los Angeles Times notes, this audiobook confirms again that Kinsey Millhone is "a wonderful character, tough but not brutish, resourceful and sensitive, a fit knight to walk those mean streets with her male predecessors."
