The motel on El Camino Real is dressed as a Swiss chalet, with snowshoes on the lobby walls and a desk clerk in a farmer’s brown wool suit. Across the street, after dinner, an electric sedan sits dark with two broad silhouettes in the front. Reacher leaves his curtains open six inches, turns off the light and waits on the end of his bed. Eight minutes later the car rolls silently into the lot, and soon a door eases open behind a suppressed pistol. When it is over, he walks next door to check on Susan Turner and finds the second intruder already face down on her carpet, and Turner standing over him holding a very thick Stephen King hardback. Chain Reaction by Lee Child and Andrew Child has plenty of bigger set pieces, but none that captures its spirit so neatly: dry, brisk and frankly delighted with its two leads.
A Ladder Made of Middlemen
The title is apt. A cybercrime agent named Bisley has been knifed behind a biker bar in northern Colorado, and his commanding officer, now a brigadier general running a new army investigative section, suspects that someone inside her own unit gave him up. Reacher goes looking for the men who did the stabbing and finds that every one of them was hired by somebody else. A getaway driver working off a debt points to two brothers from Denver. The brothers point to a voice on the phone. The voice belongs to a law firm that brokers violence for clients it never names. Each link has to be broken before the next becomes visible, and the shape gives the novel a satisfying forward pull.
It also lets the book move. Chain Reaction by Lee Child and Andrew Child begins among solar fields that run to the horizon and five windowless server halls, then relocates to the Bay Area for its long middle, where most of its best comedy lives.
Reacher Lost in Lee Child and Andrew Child’s Silicon Valley
Reacher has always been a man slightly out of his time, and Palo Alto turns that into a running joke. Taxis arrive with nobody at the wheel. A bistro menu offers payment in cryptocurrency. He reads a newspaper story about data centres guzzling water for something called artificial intelligence and is genuinely unsure what that is. The best of the locals is an acupuncturist whose surveillance of her own street is better than the army’s, and who produces a description of a suspect so detailed it reads like a psychological profile. A rumpled tech journalist named Adam Tow supplies the background briefing, and his coffee-shop argument with Reacher over whether the 1815 eruption of Mount Tambora outranks an atomic bomb, with Reacher playing human search engine, is a small treat.
The joke works because the plotting backs it up. Beneath the comedy, Chain Reaction by Lee Child and Andrew Child keeps pressing one argument: that whatever happens on a screen still has to happen somewhere on the ground, where a careful observer can find it.
Why Lee Child and Andrew Child Needed Turner
Susan Turner last shared a book with Reacher in Never Go Back, when she was a major in a jail cell and he was the stranger who helped clear her. She has since climbed three ranks, and the novel enjoys the reversal. She can get a bank to hand over his transaction history with one call; he still gets his clothes from airport gift shops. Their romance is adult and unhurried, with two frank but tender love scenes, and one chapter steps inside Turner’s head to show how she has carried their first brief affair: as a private, slightly reckless memory she has never regretted. That chapter gives Chain Reaction by Lee Child and Andrew Child an emotional undertow the co-written books have sometimes lacked.
The Price of Keeping Things Quiet
The trouble is that Turner, like Reacher, kills with almost no hesitation, and the novel never asks what that means for a serving officer. Bodies go down ravines and into fires. A phone call to a discreet team makes problems disappear. Reacher promises one prisoner a trip to the hospital and then shoots him, and the book presents it as justice served. Long-standing readers of the series accept this as part of the bargain, but a general in the Pentagon is not a drifter, and the absence of any reckoning becomes harder to ignore as the body count rises. Readers who mind graphic deaths, a baby placed in danger and a good deal of improvised execution should weigh that before starting.
Other weaknesses are smaller and more scattered:
- A suspicion about the Chief of Staff is raised on a plane and then quietly dropped.
- The new security chief shares a history with Reacher’s old unit that the plot sets up and barely uses.
- A stretch of armoury shopping, borrowed jets and forged credentials slows the build to the finale.
None of these damages the core of Chain Reaction by Lee Child and Andrew Child. The money men at the top are cartoons, all appetite and swagger, but the hired help beneath them are vivid, and the clues that crack the case are hidden in plain sight from early on.
Chain Reaction and Lee Child’s Long Game
This is the thirty-first Reacher novel and the seventh that Lee Child has written with his brother. The early joint books felt like a handover in progress, and In Too Deep was a step toward something sturdier. Chain Reaction by Lee Child and Andrew Child is the most confident of them, partly because it brings back a character from the series’ past rather than inventing a new sidekick: Turner belongs to Lee Child’s solo years. Newcomers can start here; the earlier history is summarised in a paragraph.
The Brothers Behind the Book
Lee Child, born James Grant, began his first novel in September 1994, after learning that his job in British commercial television was about to disappear. For years afterwards he started each new Reacher on that anniversary, and in 2020 he sat on the Booker Prize judging panel, an unusual honour for a genre writer. His younger brother Andrew, who also publishes thrillers as Andrew Grant, now shares the byline and much of the work. Andrew lives on a wildlife preserve in Wyoming with his wife, the novelist Tasha Alexander. The book carries a dedication to three daughters, and its warmth about families, from a widowed young mother to a pair of sisters running a gravel business, may owe something to that.
What It Leaves Behind
Chain Reaction by Lee Child and Andrew Child is out now, and it is the series in good health: funny, fair with its clues and generous to its central pair. Readers who enjoy it should try The Secret of Secrets by Dan Brown for another hero chasing a technological conspiracy across cities, and The Waiting by Michael Connelly for a detective who also trusts legwork over databases.
What lingers longest is not the violence but the tenderness between two people who know exactly what they cannot have.
