Partnerships Can Kill by Connie Shelton (A Charlie Parker Mystery Series, Book 3) by Books In Motion.com

Sharon Ortega, an old school chum of Charlie's, hires Charlie to prove that her dead restaurant partner, David, didn't commit suicide. David's recent, keyman life insurance policy won't pay for suicide, and Sharon needs the money to keep the business going. Charlie uncovers evidence of tax fraud, high level political connections, and two distinctly different sides to David's life. Amidst a confusion of relatives, she also discovers that members of David's family are lifelong friends with Vicky, the new love of Charlie's brother, Ron. And Vicky appears increasingly suspicious.
