Quick Facts

Short Summary

Cormoran Strike is still grieving his uncle Ted when a new client, Decima Mullins, hires him to prove that a mutilated corpse found in a London silver vault is her missing boyfriend. The investigation pulls Strike and his partner Robin Ellacott into a world of Freemasonry, sex trafficking, and buried family secrets. Robin, meanwhile, hides a ruptured ectopic pregnancy and struggles with her deepening feelings for Strike. As the case spirals from a single murder to a vast criminal network, both detectives confront personal trauma, threats to their lives, and the possibility that the truth may be far darker than they imagined.

Full Summary

The novel opens with Strike returning from his uncle Ted’s funeral, struggling with grief and a persistent ache in his prosthetic leg. He drives alone to Kent to meet Decima Mullins, a secretive woman living in a dilapidated cottage who believes the unidentified body found in a silver vault—officially labelled as burglar Jason Knowles—is actually her missing boyfriend, Rupert Fleetwood. Decima lists matching details: age, height, blood type, and Rupert’s disappearance on 22 May. She also reveals she has given birth to his son, Lion, and desperately wants a grave to visit.

Simultaneously, Robin collapses from a ruptured ectopic pregnancy and undergoes emergency surgery. Surgeon Mr Butler tells her that scarring from untreated chlamydia will likely prevent natural conception. Robin hides her condition from Strike, lying about a fever, and her boyfriend Ryan Murphy, a CID officer, becomes the reluctant keeper of her secret.

Strike takes the case against Murphy’s wishes. He and Robin begin digging into the silver vault murder, uncovering a web of deceit. The body was dressed in a Masonic sash, hands missing, and a Salem Cross hallmark carved into the back. Strike interviews shop owner Kenneth Ramsay, who reveals that the victim had visited a website called “Abused and Accused” and sent an email to someone named Osgood. Surveillance of the victim’s former flat leads to neighbours Mandy and Daz, who describe a suspicious woman and a curly‑haired man retrieving a heavy suitcase.

The investigation widens. Strike’s old contact Shanker warns him that the murder was a hit ordered by a powerful Freemason, and that the real target was a man trying to make a fast buck. Robin is attacked at Harrods: a stranger shoves a toy gorilla into her hand, triggering memories of her rapist. Later, a man in a gorilla mask throws a Masonic‑engraved dagger at her feet.

The partners travel to Ironbridge to interview Dilys Powell, grandmother of missing teenager Tyler Powell. There they meet charming neighbour Ian Griffiths, who offers help. But as the case develops, Griffiths’ true nature emerges. Robin discovers that Griffiths ran a sex‑trafficking ring, using the “Abused and Accused” forum to groom victims. Tyler Powell was one of his victims—murdered and buried under concrete in Griffiths’ basement.

Meanwhile, Strike faces personal crises. He learns that Bijou Watkins, a woman he had a brief fling with, may claim he is the father of her baby. A DNA test later proves otherwise, but not before the threat strains his relationship with Robin. Robin, for her part, discovers Murphy’s hidden alcoholism when she finds vodka bottles in his wardrobe. She confronts him and leaves the house they were planning to buy together.

The climax occurs in Ironbridge. Strike, Barclay, and Wardle break into Griffiths’ house. Strike discovers a trapdoor and descends into a basement where he finds Sapphire Neagle chained and nearly naked. Griffiths attacks Strike, slashing his ear, but Wardle and Barclay subdue him. Forensic teams later find the stolen silver weights and Tyler Powell’s hands, linking Griffiths to the murder.

In the aftermath, Strike attends Niall Semple’s funeral. Robin tracks Rupert Fleetwood to Sardinia, where he reveals he fled after discovering that he and Decima are half‑siblings. Decima’s reaction is one of devastation, but she remains in contact with Rupert for their son’s sake. Strike finally confesses his love to Robin, but she refuses him, citing loyalty to Murphy. Strike then proposes marriage; Robin walks away.

The novel ends with Strike reflecting on his life‑changing decision to risk vulnerability, and Robin returning to her car, her own future with Murphy uncertain.
