It starts with the body of a Hollywood producer in the trunk of a Rolls-Royce, shot twice in the head at close range - what looks like "trunk music", a Mafia hit. But the LAPD's organized crime unit is curiously uninterested, and when Harry follows a trail of gambling debts to Las Vegas, the case suddenly becomes more complex - and much more personal.

A movie director is charged with murdering an actress during sex, and then staging her death to make it look like a suicide. In a seemingly unrelated case, a loner is murdered, leaving the sheriff's department with no clues. One unsettling revelation after another leaves a retired FBI agent and an L.A. detective thinking they've unmasked a most frightening killer with almost inconceivable calculation.

Harry attacked his commanding officer and is suspended indefinitely, pending a psychiatric evaluation. At first he resists the LAPD shrink, but finally recognizes that something is troubling him and has for a long time. In 1961, when Harry was 12, his mother, a prostitute, was brutally murdered with no one ever accused of the crime.

Four years ago, LAPD detective Harry Bosch was on a movie set, asking questions about the murder of a young production assistant, when an armored car arrived with $2 million cash for use in a heist scene. In a life-imitates-art firestorm, a gang of masked men converged on the delivery and robbed the armored car with guns blazing. The crime was never resolved, and the young woman's murder was in the stack of unsolved-case files Bosch carried home the night he left the LAPD.

On New Year's Day, Detective Hieronymus "Harry" Bosch fields a call that a dog has found a bone - a bone that the dog's owner, a doctor, feels certain is human.

In Los Angeles in 1988, a 16-year-old girl disappeared from her home and was later found dead of a gunshot wound to the chest. The death appeared at first to be a suicide, but some of the evidence contradicted that scenario, and detectives came to believe this was in fact a murder. Despite a by-the-book investigation, no one was ever charged.

Working on the case, LAPD detective Harry Bosch is reminded of the primal police rule he learned long ago: Don't look for the facts, but the glue that holds them together. Soon Harry's making some very dangerous connections, starting with a dead cop and leading to a bloody string of murders that wind from Hollywood Boulevard to the back alleys south of the border.

The one good thing in Bosch's life, the person he holds most dear, is taken from him and Bosch travels to Hong Kong in an all-or-nothing bid to regain what he's lost. In a place known as Nine Dragons, as the city's Hungry Ghosts festival burns around him, Bosch puts aside everything he knows and risks everything he has in a desperate bid to outmatch the triad's ferocity.

Harry Bosch is up to his neck in a case that has transfixed all of celebrity-mad Los Angeles: a movie director is charged with murdering an actress during sex and then staging her death to make it look like a suicide. Bosch is both the arresting officer and the star witness in a trial that has brought the Hollywood media pack out in full-throated frenzy. Meanwhile, Terry McCaleb is enjoying an idyllic retirement on Catalina Island when a visit from an old colleague brings his former world rushing back.

Harry Bosch has been given three years before he must retire from the LAPD, and he wants cases more fiercely than ever. In one morning, he gets two. DNA from a 1989 rape and murder matches a 29-year-old convicted rapist. Was he an eight-year-old killer, or has something gone terribly wrong in the new Regional Crime Lab? Then Bosch and his partner are called to a death scene fraught with internal politics....

In a case that spans 20 years, Harry Bosch links the bullet from a recent crime to a file from 1992, the killing of a young female photographer during the L.A. riots. Harry originally investigated the murder, but it was then handed off to the Riot Crimes Task Force and never solved. Now Bosch's ballistics match indicates that her death was not random violence, but something more personal, and connected to a deeper intrigue. Like an investigator combing through the wreckage after a plane crash, Bosch searches for the "black box", the one piece of evidence that will pull the case together.

In 1993, Marie Gesto disappeared after walking out of a supermarket. Harry Bosch worked the case but couldn't crack it, and the 22-year-old was never found. Now, more than a decade later, with the Gesto file still on his desk, Bosch gets a call from the district attorney. A man accused of two heinous murders is willing to come clean about several others, including the killing of Marie Gesto.

In the LAPD's Open-Unsolved Unit, not many murder victims die almost a decade after the crime. So when a man succumbs to complications from being shot by a stray bullet nine years earlier, Bosch catches a case in which the body is still fresh, but all other evidence is virtually nonexistent. Now Bosch and rookie Detective Lucia Soto, are tasked with solving what turns out to be a highly charged, politically sensitive case.

Detective Harry Bosch has retired from the LAPD, but his half-brother, defense attorney Mickey Haller, needs his help. The murder rap against his client seems ironclad, but Mickey is sure it's a setup. Though it goes against all his instincts, Bosch takes the case. With the secret help of his former LAPD partner, Lucia Soto, he turns the investigation inside the police department. But as Bosch gets closer to discovering the truth, he makes himself a target.

A body has been found on the overlook near Mulholland Drive. The victim, identified as Dr. Stanley Kent, has two bullet holes in the back of his head, from what looks like an execution-style shooting. LAPD detective Harry Bosch is called out to investigate. As soon as Bosch begins retracing Dr. Kent's steps, contradictions emerge. While Kent doesn't seem to have had ties to organized crime, he did have access to dangerous radioactive substances from just about every hospital in Los Angeles County.
