"O" Is For Outlaw by Sue Grafton

Kinsey Millhone receives a piece of her past when a storage unit scavenger calls with a box of items from her first marriage to Mickey Magruder. A 14 year old letter leads Kinsey to believe that Mickey was innocent of the incident that caused him to lose his job as a policeman as well as ending their marriage. Feeling regret, she tries to find Mickey only to learn that he is hospitalized, in a coma, from gunshot wounds. Grafton tells a tale of remorse, graft and corruption, leading the reader through another story of Kinsey Millhone, private investigator.
