The Wrong Side of Goodbye

This novel finds semi-retired Harry Bosch alternating between two investigations. As a private detective he is summoned by billionaire industrialist Whitney Vance. The elderly, never-married Vance wants Bosch to track down an old girlfriend to know if he has an heir to whom he can leave his fortune. As a volunteer part-time officer for San Fernando, Bosch is involved in the search for a serial rapist.

In college, 18 year old Vance had an eight-month romance with 16 year old Vibiana Duarte. Their respective families objected to the couple: Duarte's father disliked that Vance was not Catholic, while Vance's eugenicist father disapproved of his son dating a Mexican. She may have been pregnant when they last saw each other in 1950. Bosch investigates under an order of confidentiality and finds Vance actually had a son, Dominick Santanello, born shortly before his mother's suicide and adopted soon after birth. Santanello was killed in action during the Vietnam War, so Bosch has to inquire further. He discovers Dominick had a daughter who is named Vibiana Veracruz after her grandmother. Vibiana Veracruz is alive and active as an artist and a sculptor. Bosch receives, in the mail, a will hand-written by Vance giving $10 million to his longtime secretary Ida Forsythe and the remainder of his estate to his heir and also names Bosch as the executor. Bosch hires his half-brother Mickey Haller to represent him. A power struggle ensues between Vance's bodyguard Sloan and his personal assistant Ida Forsythe, with Bosch committed to his vow of secrecy and unsure which of them he can trust. When Vance is found dead at his desk investigators first believed he died of natural causes but days later inform Bosch that the elderly man was murdered. Noting inconsistencies in the case, Bosch eventually discovers a complex will fraud initiated by Forsythe when she believed Vance was dying. She confesses having killed Vance when he recovered from a short illness, to avoid his discovery of her chicanery. Eventually Vibiana Veracruz receives a large portion of Whitney's estate per an old will, and uses the money to buy out developers who wanted to rezone her neighborhood.

The parallel crimes Harry is investigating are those perpetrated by a serial rapist who they have code-named The Screen Cutter after his method of entry to victims' homes. Investigation reveals all the victims lived in neighborhoods frequented by a city code officer, leading Bosch to suspect Dockweiler, a former San Fernando officer known for his misogynistic attitudes. In an earlier force reduction Officer Dockweiler had been transferred to city code enforcement. Bosch shoots and wounds Dockweiler, who had taken as hostages the police chief and the police captain captive. Bosch then has to find and rescue his partner Bella Lourdes, whom Dockweiler had abducted and imprisoned when she too came to suspect him as the Screen Cutter.
