Lincoln lawyer Mickey Haller and LAPD Detective Harry Bosch team up in this new novel by Michael Connelly. Things are finally looking up for defence attorney Mickey Haller. After two years of wrong turns, Haller is back in the courtroom. When Hollywood lawyer Jerry Vincent is murdered, Haller inherits his biggest case yet: the defense of Walter Elliott, a prominent studio executive accused of murdering his wife and her lover. But as Haller prepares for the case that could launch him into the big time, he learns that Vincent's killer may be coming for him next. Enter Harry Bosch. Determined to find Vincent's killer, he is not opposed to using Haller as bait.
