The Law of Innocence by Michael Connelly

Lawyer Mickey Haller is charged with murder after the body of Sam Scales, a former client, is found in the trunk of Haller's car after a traffic stop. Mickey knows he was framed, but by whom? Defending himself against the charges isn't easy, since he is in jail awaiting trial, which takes a toll on him both mentally and physically. With help from his half-brother (Harry Bosch), his family, and legal team, Mickey fights to clear his name and get his life back.
