The Silkworm Summary: A Staged Murder in Literary London
Spoiler Warning: This section reveals the killer’s identity and the ending.
In a freezing November London, Cormoran Strike is rebuilding his private detective agency after his first major success. Robin Ellacott, his assistant, wants more than administrative work, though her fiancé Matthew Cunliffe disapproves.
A woman named Leonora Quine arrives without an appointment and asks Strike to find her husband, the struggling novelist Owen Quine.
Owen has been missing for ten days after a public row with his agent, Elizabeth Tassel, over his manuscript Bombyx Mori. Leonora believes he is hiding at a writers’ retreat called Bigley Hall. Strike starts with Christian Fisher of Crossfire Press, who says Quine is not at the retreat.
Fisher explains that the manuscript is a malicious roman à clef that parodies nearly everyone in Quine’s literary circle.
The manuscript depicts Tassel as a bloated parasite called the Tick, publisher Daniel Chard as a necrophiliac, rival Michael Fancourt as Vainglorious, editor Jerry Waldegrave as a cuckolded castrator, and mistress Kathryn Kent as Harpy.
Copies are leaking across London, and people are threatening libel suits. Strike visits Tassel, then Kathryn Kent, gathering clues about Quine’s final days.
Suspicious of Quine’s long silence, Strike checks an abandoned house at 179 Talgarth Road. The property was jointly owned by Quine and Michael Fancourt after their friend Joe North died.
Inside, Strike finds a chemical smell of acid and the smell of decay. On the top floor lies Quine’s decomposing body, bound, disemboweled, and doused in acid.
Seven place settings are arranged around the body, copying the final scene of Bombyx Mori.
The Metropolitan Police, led by DI Richard Anstis, focus on Leonora Quine. She had keys to the house, past butcher experience, and access to the manuscript.
Police find online purchases of ropes, overalls, wellington boots, and a burqa on the Quines’ credit card. A bloodstained rag appears in the family lockup. Leonora is arrested.
Strike does not believe Leonora killed her husband. He cancels other clients and works with Robin to trace suspects. After a fall at West Brompton station, his knee is severely swollen, but he keeps working. Robin researches suspects and finds a hostile blog user called Pippa2011.
Outside the office, a tall cloaked figure attacks Strike with a Stanley knife. He overpowers the attacker, who is Pippa Midgley.
Pippa is a young transgender woman who met Quine on a writing course. She reveals that Kathryn Kent received the full manuscript on November 9, meaning Kathryn lied to the police.
Strike goes to Devon to interview publisher Daniel Chard. Chard accuses Jerry Waldegrave of helping Quine write the manuscript. Strike later meets a drunken Waldegrave and uncovers older secrets.
Years earlier, Fancourt’s first wife Elspeth died by suicide after an anonymous parody of her novel. Fancourt blamed Quine, starting a twenty-five-year feud.
Strike also learns that Waldegrave’s wife Fenella had an affair with Fancourt, and the manuscript implied Waldegrave’s daughter was Fancourt’s child.
Strike realizes the leaked Bombyx Mori was not written by Quine. It was written by the killer: Elizabeth Tassel. Tassel had written the anonymous parody of Elspeth Fancourt years earlier. Quine blackmailed her for twenty-six years. To stop the blackmail, she convinced Quine to fake his disappearance on Bonfire Night for publicity, then isolated him at Talgarth Road.
Tassel knocked Quine unconscious, killed him exactly as described in her rewritten manuscript, removed his organs, and used acid to destroy forensic traces.
She distributed the offensive manuscript to cast suspicion on rivals and used Quine’s credit card to frame Leonora.

To prove the theory, Strike asks his friend Dave Polworth to dive off the Cornish coast near Gwithian. Polworth recovers the typewriter Tassel used to write the fake manuscript, stained with acid and wrapped in a burqa.
Strike also retrieves a used typewriter ribbon hidden in Orlando Quine’s pajama case. The ribbon contains a line from the real manuscript, proving Quine’s version was different.
At a dinner party at the Chelsea Arts Club, Strike confronts Tassel and Fancourt. Tassel flees and gets into a taxi driven by a disguised Robin.
Realizing she is being taken to Scotland Yard, Tassel attacks Robin and causes a crash in Sloane Square. Strike and his half-brother Al pull Robin from the wreckage and stop Tassel, who is arrested.
A week later, Leonora is cleared.
The real manuscript is set for publication, giving Leonora and Orlando financial security.
Strike gives Robin a surveillance course, confirming her place as his full partner.
