Come Crawling by Mark A. Davis

Private Investigator Mitch Morgan's first assignment at Callahan Investigation Agency may very well be his last. His investigation of a minor injury claim uncovers a network of criminal activity, while a second case assignment places his past and present lives on a collision course that culminates in his arrest on numerous felony charges. He sits in court awaiting his sentencing and recalls the cases to a journalist while playing a cat-and-mouse game with an overzealous prosecutor that may end his professional career, and a budding relationship with a potential love interest.
