Never Go Back (jack Reacher, #18)

The eighteenth novel in Lee Child's Jack Reacher series follows the former military police commander as he returns to the headquarters of his old unit, only to find himself ensnared in false charges, conspiracy, and murder stretching from Virginia to Afghanistan to Los Angeles.

Jack Reacher, a retired army major and former commanding officer of the 110th MP Special Unit, a military police investigative command, has traveled from South Dakota to the unit's headquarters in Rock Creek, Virginia. He has spoken by phone with Major Susan Turner, the 110th's current commanding officer, and wants to ask her to dinner. When he arrives, Turner is gone. In her place sits Lieutenant Colonel Morgan, a troubleshooter who informs Reacher that Turner has been relieved of command. Morgan reveals two legal problems tied to Reacher's personnel file. The first is a sixteen-year-old allegation from a gang member named Juan Rodriguez, who left a sworn affidavit claiming Reacher beat him severely; Rodriguez has since died from his injuries. The second involves a civilian named Candice Dayton, who alleges she had an affair with Reacher and that he fathered her child. Using Title 10 of the U.S. Code, which governs the armed forces, Morgan formally recalls Reacher to active duty, reinstating his rank and confining him to a five-mile radius.

Reacher begins investigating. Sergeant Leach, the unit's reception desk noncommissioned officer, reveals that Turner was supposedly sent to Afghanistan but never arrived and is rumored to be held in the guardhouse at Joint Base Dyer-Helsington House. Reacher confirms Turner is detained on a bribery charge. Two lawyers are assigned to Reacher's cases. Major Sullivan presents damning evidence in the Rodriguez matter, including Reacher's own daily summary showing he visited Rodriguez and a hospital report documenting the injuries. Captain Edmonds explains that Dayton claims her fourteen-year-old daughter, Samantha, is Reacher's child from an affair during his posting to Camp Red Cloud in South Korea. Reacher insists he does not remember Dayton.

Two figures identified only as Romeo and Juliet monitor events through military computer systems, coordinating four soldiers as enforcers, including a large team leader with a shaved head and small, misshapen ears. Morgan confines Reacher to quarters after Reacher launches an unauthorized air search for two 110th soldiers, Weeks and Edwards, who have missed consecutive radio checks in Afghanistan. That afternoon, Colonel Moorcroft, Turner's defense lawyer, is beaten half to death in southeast Washington, and Warrant Officer Pete Espin of the 75th Military Police arrests Reacher on suspicion.

In his cell, Reacher learns that Weeks and Edwards have been found dead in the Hindu Kush mountains, shot with nine-millimeter rounds almost certainly from U.S. Army sidearms. Reacher engineers an escape: He lures Sullivan and the duty captain into his cell during a meeting and locks them in, takes Sullivan's car key and army ID, then tricks additional personnel into empty cells. He reaches Turner, whom he meets for the first time, and they flee using Sullivan's car and stolen IDs to pass through three security checkpoints.

On the run, Turner explains what she knows. She sent Weeks and Edwards to follow a rumor from a Pashtun informer: an unknown American officer had been seen heading north in Afghanistan to meet with a tribal elder. Reacher reasons that the conspirators were intercepting communications through the military base at Bagram, and that the murders occurred before Turner's arrest, meaning the conspirators already knew everything Weeks and Edwards had reported. He concludes Turner possesses some piece of information she has not recognized as significant.

They head west, acquiring cash, a vehicle, and eventually new identities. Turner recalls that the original intelligence report included an "A.M." reference number for the tribal elder, a designation meaning "Afghan Male" followed by a four-digit code indicating the man is already in a U.S. intelligence database. Sergeant Leach drives from Rock Creek to deliver undercover identity documents and a page from the duty captain's legal pad on which A.M. 3435 had been doodled, the only surviving record after Morgan removed the official transcript.

Captain Edmonds identifies A.M. 3435 as Emal Gholam Zadran, a forty-two-year-old Afghan from a poppy-growing family. Seven years earlier, Zadran was suspected of buying hand grenades from U.S. forces and selling them to the Taliban but was released, a decision requiring approval from the senior intelligence commander in Afghanistan. Two pursuers board the same flight to California; Reacher incapacitates them. Edmonds confirms all four are active-duty soldiers from a logistics company at Fort Bragg, North Carolina, trained for moving sensitive materials into and out of Afghanistan. Their team was assembled by Morgan, who was placed at Bragg by an Assistant Deputy Chief of Staff named Crew Scully.

In Los Angeles, Reacher and Turner locate the address where Dayton supposedly lives, while the FBI, the 75th MP, and the remaining Fort Bragg soldiers watch the same house. Turner shoots and kills the third pursuer, Rickard, after he follows her onto Mulholland Drive. At a nearby diner, Sam Dayton, the fourteen-year-old girl from the house, approaches Reacher. She is intelligent and observant, having noticed the surveillance vehicles on her street. Meanwhile, Sullivan discovers that the Rodriguez affidavit was disproved years ago by an investigation ordered by General Leon Garber, Reacher's former mentor; Rodriguez was beaten by five men from El Segundo, and the affidavit was fabricated as a fraud. Espin, who has tracked Reacher to the diner, reveals that the Dayton paternity claim is also manufactured: Dayton never left Los Angeles County, and the affidavit was purchased by someone calling himself "Romeo," paid from a Cayman Islands account on the same morning Turner was arrested. Sam points out the blonde waitress in the restaurant as her mother. Reacher has never met the woman, and the girl is not his daughter.

Reacher persuades Espin to consider the larger conspiracy, and Espin agrees to a twenty-four-hour truce. They fly back to Washington together. During the flight, Edmonds identifies Scully's closest friend and West Point classmate: Gabriel Montague, the army's Deputy Chief of Staff for intelligence, whose position would grant access to Homeland Security systems. Reacher connects the name Montague to Shakespeare's Romeo, the alias used to purchase the fraudulent affidavit.

In Washington, Leach traces the pre-paid phone of Shrago, the Fort Bragg team leader, to a Georgetown private members' club called Dove Cottage. Staking out the building before dawn, Reacher and Turner watch older men leave the club radiating unusual serenity. Reacher connects the club's name to its literary namesake: the original Dove Cottage in England's Lake District was famous not only as the home of poet William Wordsworth but as the residence of Thomas De Quincey, author of Confessions of an English Opium-Eater. The full picture emerges: Scully and Montague are importing opium from the Zadran brothers' poppy fields, concealed in returning military shipments, for their exclusive club. Reacher confronts and defeats Shrago near Lafayette Square. At dawn, two gunshots sound from inside Dove Cottage. Scully and Montague have killed themselves rather than face exposure. Inside, Reacher and Turner find them dead amid opium pipes. Espin confirms Shrago's confession led to Morgan's arrest. Colonel Temple, Turner's defense attorney, obtains a permanent stay on Turner's confinement order, while the Rodriguez and Dayton cases are both exposed as frauds.

Turner resumes command of the 110th. She and Reacher share a final dinner near Rock Creek, acknowledging what they both know: she is devoted to her command, and he cannot stay in one place. They say goodbye. Reacher drops his phone in the trash, crosses the street, and sits alone on a northbound bus bench, heading onward and away.
