Strike’s agency is busy after the Lula Landry success. Yet he takes on Leonora Quine’s case; she wants him to track down her missing husband, novelist Owen Quine.

He speaks to Quine’s agent, Liz Tassell, who was furious because Quine’s latest book - Bombyx Mori - libeled many people.

Strike is taunted by a picture of his ex, Charlotte, and her new fiancé, on the cover of a magazine. His meeting with Robin’s fiancé, Matthew, is very awkward. Strike’s shocked the wedding is only 8 weeks away, Robin’s shocked that Strike’s thinking of hiring another investigator.

Strike learns that Quine’s mistress, Kathryn Kent, was hurt by her depiction in Bombyx Mori and then discovers that Quine co-owned a house with a rival novelist, Andrew Fancourt. He finds the Quine’s body there, disemboweled and surrounded by plates. Robin shows him Bombyx Mori - Quine's grisly killing matching the death of the hero.

DI Richard Anstis instantly suspects Leonora, but Strike is unconvinced. When Matthew’s mum dies, Robin is torn between personal and professional priorities. She chooses to help Strike and drives him to Devon to see Quine’s publisher (Chard) rather than going to Yorkshire with Matthew. Chard thinks Quine didn’t write the book alone - he suspects Jerry Waldegrave (Quine’s Editor).

Robin confronts Strike about her desire to be an investigator - he tells her that it will be difficult if Matthew doesn’t support her. They rush back to London and Robin only just catches her train to Yorkshire. Strike hears Leonora has been arrested.

The final episode of Strike - The Cuckoo's Calling will air on BBC One this coming Sunday, September 3rd, starring Tom Burke as Cormoran Strike and Holliday Grainger as Robin Ellacott. No word yet on international or U.S. broadcasting dates.
