A year has passed since LAPD detective Renée Ballard quit the force. But after the chief of police himself tells her she can write her own ticket within the department, Ballard takes back her badge, leaving “the Late Show” to rebuild and lead the cold case unit at the elite Robbery-Homicide Division. For years, Harry Bosch has been working a case that haunts him --- the murder of an entire family by a psychopath who still walks free. Ballard makes Bosch an offer: come volunteer as an investigator in her new Open-Unsolved Unit, and he can pursue his “white whale” with the resources of the LAPD behind him. The first priority for Ballard is to clear the unsolved rape and murder of a 16-year-old girl.

There’s chaos in Hollywood at the end of the New Year’s Eve countdown. Working her graveyard shift, LAPD detective Renée Ballard waits out the traditional rain of lead as hundreds of revelers shoot their guns into the air. Only minutes after midnight, Ballard is called to a scene where a hardworking auto shop owner has been fatally hit by a bullet in the middle of a crowded street party. Ballard quickly concludes that the deadly bullet could not have fallen from the sky and that it is linked to another unsolved murder --- a case at one time worked by Detective Harry Bosch. At the same time, Ballard hunts a fiendish pair of serial rapists, the Midnight Men, who have been terrorizing women and leaving no trace.

On the night he celebrates a big win, defense attorney Mickey Haller is pulled over by police, who find the body of a former client in the trunk of his Lincoln. He is immediately charged with murder but can’t post the exorbitant $5 million bail slapped on him by a vindictive judge. Haller elects to represent himself and is forced to mount his defense from his jail cell in the Twin Towers Correctional Center in downtown Los Angeles. He knows he’s been framed, whether by a new enemy or an old one. As his trusted team, including his half-brother, Harry Bosch, investigates, Haller must use all his skills in the courtroom to counter the damning evidence against him.

Back when Harry Bosch was just a rookie homicide detective, he had an inspiring mentor who taught him to take the work personally and light the fire of relentlessness for every case. Now that mentor, John Jack Thompson, is dead, and his widow gives Bosch a murder book, one that Thompson took with him when he left the LAPD 20 years before --- the unsolved killing of a troubled young man. Bosch takes the murder book to Detective Renée Ballard and asks her to help him discover what about this crime lit Thompson's fire all those years ago. As she begins her inquiries, Ballard finds aspects of the initial investigation that just don't add up. They soon arrive at a disturbing question: Did Thompson steal the murder book to work the case in retirement, or to make sure it never got solved?

Detective Renée Ballard is working the night beat and returns to Hollywood Station to find a stranger rifling through old file cabinets. The intruder is retired detective Harry Bosch, working a cold case that has gotten under his skin. Ballard can't let him go through department records, but when he leaves, she looks into the case herself and feels a deep tug of empathy and anger. The murder, unsolved, was of 15-year-old Daisy Clayton, a runaway on the streets of Hollywood who was brutally killed. Now Ballard joins forces with Bosch to find out what happened to Daisy, and to finally bring her killer to justice. But this new partnership is put to the test when the case takes an unexpected and dangerous turn.

Harry Bosch is back as a volunteer working cold cases for the San Fernando Police Department and is called out to a local drug store where a young pharmacist has been murdered. Bosch and the town's three-person detective squad sift through the clues, which lead into the dangerous, big business world of pill mills and prescription drug abuse. Meanwhile, an old case from Bosch's LAPD days comes back to haunt him when a long-imprisoned killer claims Bosch framed him, and seems to have new evidence to prove it. The two unrelated cases wind around each other like strands of barbed wire. Along the way, Bosch discovers that there are two kinds of truth: the kind that sets you free and the kind that leaves you buried in darkness.

Renée Ballard works the night shift in Hollywood, beginning many investigations but finishing none, as each morning she turns everything over to the day shift. A once up-and-coming detective, she's been given this beat as punishment after filing a sexual harassment complaint against a supervisor. But one night she catches two assignments she doesn't want to part with: the brutal beating of a prostitute left for dead in a parking lot and the killing of a young woman in a nightclub shooting. Against orders and her partner's wishes, she works both cases by day while maintaining her shift by night. As the investigations entwine, they pull her closer to her own demons and the reason she won't give up her job.

One of Southern California's biggest moguls is nearing the end of his life and is haunted by one regret. When he was young, he had a relationship with a Mexican girl, his great love. But soon after becoming pregnant, she disappeared. Did she have the baby? And if so, what happened to it? Desperate to know if he has an heir, the dying magnate hires Harry Bosch, California's newest private investigator. As he begins to uncover the haunting story --- and finds uncanny links to his own past --- Harry knows he cannot rest until he finds the truth. At the same time, he finds himself tracking a serial rapist who is one of the most baffling and dangerous foes he has ever faced.

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.

In the LAPD's Open-Unsolved Unit, not many murder victims die almost a decade after the crime. But when a man succumbs to complications from being shot by a stray bullet 10 years earlier, detectives Harry Bosch and Lucia Soto are tasked with solving what turns out to be a highly charged, politically sensitive case. Beginning with the bullet that's been lodged in the victim's spine, they must pull new leads from years-old information, which soon reveal that this shooting may have been anything but random.

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, Detective Harry 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.

When Mickey Haller learns that a murder victim was his own former client, a prostitute he thought he had rescued and put on the straight and narrow path, he knows he is on the hook for this one. Far from saving her, Mickey may have been the one who put her in danger. Haunted by the ghosts of his past, Mickey must work tirelessly and bring all his skill to bear on a case that could mean his ultimate redemption --- or proof of his ultimate guilt.

Harry Bosch links the bullet from a recent crime to the unsolved killing of a young female photographer during the 1992 L.A. riots. His ballistics match now indicates that her death was not random violence, but something more personal. 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.

Nearing the end of his career, Harry Bosch wants cases more than ever. In one morning, he gets two. DNA from a 1989 rape and murder matches a 29-year-old convicted rapist. Meanwhile, Councilman Irvin Irving's son jumped or was pushed from a window, and Irving, Bosch's longtime nemesis, has demanded that Bosch handle the investigation. Relentlessly pursuing both cases, Bosch makes two chilling discoveries.

Longtime defense attorney Mickey Haller is recruited to change stripes and prosecute the high-profile retrial of a brutal child murder. 

Mickey Haller has fallen on tough times. He expands his business into foreclosure defense, only to see one of his clients accused of killing the banker she blames for trying to take away her home.
