Two Kinds of Truth (harry Bosch, #20; Harry Bosch Universe, #31)

The twentieth novel in Michael Connelly's Harry Bosch series follows retired Los Angeles Police Department (LAPD) detective Harry Bosch, now a volunteer cold case investigator for the small San Fernando Police Department (SFPD), as he confronts two cases: a present-day double murder tied to a drug trafficking ring and a decades-old conviction under attack.

Bosch works out of a repurposed jail cell, reviewing the long-cold disappearance of a woman named Esme Tavares, when his colleague Detective Bella Lourdes warns that LAPD and District Attorney representatives are heading his way. His former partner, Detective Lucia Soto, arrives with her current partner, Detective Bob Tapscott, and Deputy District Attorney Alex Kennedy of the newly created Conviction Integrity Unit (CIU), a division that reviews potential wrongful convictions. Kennedy reveals the CIU has been reinvestigating the 1988 conviction of Preston Borders, whom Bosch put on death row for the rape and murder of aspiring actress Danielle Skyler. New forensic analysis has found semen on Skyler's clothing belonging to Lucas John Olmer, a convicted serial rapist who died in prison in 2015, rather than to Borders. Video shows the original evidence box seals, signed by Bosch in 1988, appear intact. Kennedy warns the D.A. will join Borders's attorney in seeking to vacate the conviction and that a civil claim may target Bosch personally. Bosch insists the case was solid, but Kennedy refuses him time or access to investigate.

Before Bosch can respond further, Lourdes reports two homicides at La Farmacia Familia, a pharmacy on the town's main strip. The victims are pharmacist José Esquivel Sr. and his son José Jr., a recent pharmacy school graduate, killed in a pattern Bosch recognizes as targeted and personal. Security footage confirms two masked gunmen executed both victims and looted prescription drawers within seconds.

That night, Bosch finds the CIU's complete file in his mailbox, which he believes Soto left. He reviews the original investigation with his late partner, Frankie Sheehan. Skyler was found raped, strangled, and mutilated in her Toluca Lake apartment; a staged break-in pointed to someone she knew. Through Skyler's friends, the detectives learned of a man named Preston who had angrily returned to her door demanding sex. They identified him as Preston Borders through audition logs at the casting office where Skyler worked and caught him lying during a voluntary interview. A search warrant yielded the critical evidence: a sea-horse pendant, Skyler's most prized possession, hidden in Borders's apartment. At trial, Borders claimed he had bought a matching pendant; the jury convicted him and he was sentenced to death.

The pharmacy investigation accelerates when Lourdes discovers José Jr. filed a complaint about a Pacoima clinic overprescribing oxycodone. Bosch and Lourdes conduct surveillance, watching a van shuttle pill shills, addicts recruited to fill fraudulent prescriptions, from the clinic to Whiteman Airport, where they board a plane that departs without a flight plan. Bosch's former partner Jerry Edgar, now a Medical Board of California investigator, identifies the operation as a Russian-Armenian syndicate led by a figure called Santos, operating from the desert near the Salton Sea, and warns that a previous Drug Enforcement Administration (DEA) informant was thrown from a plane.

Meanwhile, Bosch pursues the Borders frame. He learns that Borders's only visitor at San Quentin is attorney Lance Cronyn, who also appeared on the visitor list of the dead Olmer, linking the lawyer to both men. Bosch's half brother and attorney, Mickey Haller, confirms the city must indemnify Bosch if he acted in good faith. Haller also reveals that Borders's original defense attorney, David Siegel, known as Legal Siegel and reported dead in a bar association obituary, is actually alive in a nursing home. Reviewing prosecution records, Bosch discovers Cronyn obtained a court order to split DNA evidence during Olmer's trial, but the genetic material was never returned, giving Cronyn the means to plant Olmer's DNA in the Skyler evidence box.

DEA agent Charlie Hovan proposes an undercover operation to locate Santos, for whom he holds an unexecuted arrest warrant under the Racketeer Influenced and Corrupt Organizations Act (RICO). Bosch's age makes him a plausible Medicare-eligible recruit, and despite concerns, he agrees. Haller's investigator, Dennis "Cisco" Wojciechowski, a former opioid addict and member of the Road Saints motorcycle club, provides a cane concealing a stiletto blade. While reviewing the evidence-box video, Cisco spots Terrence Spencer, an LAPD property officer, watching Soto open the box. Investigation reveals Spencer is trapped by a mortgage with a looming lump-sum payment arranged by Katherine Cronyn, Lance's wife and law partner. Bosch confirms Spencer's clandestine link to Cronyn through a burner-phone call. The scheme becomes clear: the Cronyns recruited the financially desperate Spencer to tamper with the evidence, planting Olmer's DNA so Borders could be freed and Cronyn could collect millions from a wrongful-conviction settlement.

Bosch goes undercover as a drifter addict, equipped with a GPS transmitter and an emergency rescue chain. After a strip search at the clinic, he is flown with other shills to a shantytown near the Salton Sea. There, he discovers two Russian men whose physiques match the pharmacy shooters. One catches Bosch scouting and plays Russian roulette with his confiscated revolver; the gun clicks harmlessly because the DEA filed down the firing pin. Over the following days, Bosch fills prescriptions across California and arranges a staged bust to remove an addict named Brody, who attacked him, and to pull a woman named Elizabeth Clayton out of the operation and into detox.

On Sunday, the Russians single out Bosch. On the plane, one shows him a Los Angeles Times photo identifying him as a detective, from a story Bosch concludes Kennedy leaked. Declared a cop and ordered to jump over the Salton Sea, Bosch triggers his emergency signal and kills the armed Russian with the hidden stiletto. The second Russian leaps from the open door. Bosch commandeers the plane and flies to Whiteman under DEA escort.

After debriefing, Bosch reads the damaging Times article naming him as the detective who allegedly planted evidence. His phone holds 17 messages, the most painful from his daughter Maddie, who feared he had harmed himself; he calls her first. Bosch learns Clayton was released from jail before entering detox and finds her semi-conscious after overdosing at a predatory doctor's clinic. With Edgar's help, he brings her to the Road Saints clubhouse, where Cisco oversees her withdrawal using the locked-room method that helped Cisco overcome his own addiction. The next morning, Clayton is hostile and desperate. Bosch invokes the name Daisy, the daughter memorialized in a tattoo on her shoulder, and Clayton tearfully agrees to try.

At the Wednesday hearing, Judge John Houghton grants Haller's motion to intervene on Bosch's behalf. In a closed conference, Haller lays out the frame: the DNA last in Cronyn's possession, Spencer's financial desperation and his presence on the evidence-box video, and a videotaped interview with Legal Siegel, who confirms the detectives' integrity was never in question. Haller announces Spencer is in the hallway ready to testify, a calculated bluff. Borders erupts, cursing Cronyn and declaring he will reveal everything. Kennedy withdraws the state's support for the habeas petition, a legal challenge seeking to overturn the conviction, and Borders withdraws it himself. Houghton finds both Cronyns in criminal contempt and demands the D.A. publicly exonerate Bosch. A search of Spencer's locker reveals old evidence stickers he used to open and reseal the tampered box.

Bosch gives Cisco his savings, nearly $10,000, to fund Clayton's admission to a rehabilitation facility. Soto visits to apologize for following the evidence to a wrong conclusion; Bosch accepts and asks her to pull the cold case of Daisy Clayton, Elizabeth's 15-year-old daughter, who was murdered in Hollywood in 2009. The Esme Tavares case, which Bosch had assumed was a homicide, resolves when Tavares contacts him: She is alive, having fled an abusive husband and assumed a new identity. SFPD Chief Anthony Valdez crumples the old MISSING flyer. Bosch leaves the photo on his cell wall as a reminder of how wrong he had been. In the final scene, Bosch calls Soto, who has found angles in the neglected Daisy Clayton file, and asks to join the investigation.
