The Last Devil To Die Ending Explained: Spoilers, Climax, and Character Fates

Literal Account of the Climax

The novel’s central mystery — who killed eighty‑year‑old antiques dealer Kuldesh Sharma — is resolved in the final chapters through a chain of revelations.

Elizabeth’s realisation: After her husband Stephen dies by assisted suicide (Chapter 60), Elizabeth weeps for him but also for the fox Snowy. In a moment of clarity she connects two memories: Stephen spoke often of Kuldesh in his final days, and he asked her to “take care of the allotment.” She picks the lock on the allotment shed and finds a new spade — Stephen had hidden something for her. She deduces that Kuldesh’s second, untraceable phone call on the day of his death was to Stephen, and that Stephen buried the ancient Mesopotamian “sin box” (the container that held the heroin) in the allotment because he knew Elizabeth would find it.

The box’s true value: At a dinner with all suspects (Chapter 53), Elizabeth learns that the heroin was worth only £100,000 — a sum too small to justify the wave of murders. Garth (the Canadian forger’s partner) reveals the truth in Chapter 79: the box itself is a 6,000‑year‑old carved bone artefact worth tens of millions. The Afghan smugglers had never told local dealer Mitch Maxwell what they were really shipping. Everyone — including Nina Mishra, an archaeologist — had been chasing the box, not the heroin.

Kuldesh’s killer: Elizabeth arranges for a fake fire alarm at Professor Jonjo Mellor’s office, and a camera rigged by her contact catches Nina stealing the box. Earlier evidence (Chapter 84‑85) confirms that Nina Mishra killed Kuldesh to obtain the box. When Garth confronts her at a motorway service station, she admits the killing, saying it was necessary because Kuldesh refused to hand over the artefact.

Fate of the box: Garth pays Nina five million pounds for the box (as Elizabeth instructed) and then hands it over to Elizabeth. She later places Stephen’s ashes inside it and sends the box to Baghdad, honouring Stephen’s final wish and closing the circle of the story.

Stephen’s death (Chapters 60–61): In one of the most emotional scenes of the series, Elizabeth helps Stephen end his life with dignity. He injects himself, shares a final philosophy about time, and dies in her arms. The funeral and aftermath show the Thursday Murder Club paralysed by grief.

Major Character Outcomes

Resolved and Unresolved Threads

Resolved:

• Who killed Kuldesh? → Nina Mishra.
• Why was he killed? → To steal the ancient box.
• What was the box? → A 6,000‑year‑old Mesopotamian sin box worth millions.
• Stephen’s death → He chose assisted suicide with Elizabeth’s help.
• Mervyn’s money → Recovered after the fraud scam is exposed.
• Luca Buttaci’s death → Garth threw him off a multi‑storey car park.
• Dom Holt’s death → Ordered by Connie Johnson.
• The heroin → Never recovered; the box becomes the real prize.

Unresolved:

• Will Connie Johnson face justice? She remains free but plagued by guilt.
• Elizabeth’s future: She plans to follow the Bethany Waites case overseas; we do not see the outcome.
• Joyce’s new friendship with Edwin Mayhew — a potential new romance or just a companion?
• Ibrahim’s trust: He was wounded by Connie’s betrayal; the book ends with him still healing.
• The Afghan network: Hanif survives and considers leaving the trade, but the organisation remains intact.

Theme Resolution

• Grief and Loss: The novel ends with a powerful meditation on grief. Elizabeth lies on the grass after the fire alarm, crying for the first time since Stephen’s death, and smiles. Joyce reflects on widowhood and the “miracle of daffodils.” The theme is resolved not by moving on, but by learning to live with loss.
• Friendship and Loyalty: The Thursday Murder Club stands together through Stephen’s death. Joyce cleans Elizabeth’s flat; Ron and Ibrahim are present. Their loyalty is the bedrock that allows Elizabeth to function.
• Deception and Fraud: The entire plot is built on deception — the hidden value of the box, the fake romance scam targeting Mervyn, and the double crosses among criminals. By the end, truth emerges but not without cost.
• Mortality and Aging: Stephen’s death, Kuldesh’s murder, and the violent ends of younger criminals underscore the inevitability of death. The elderly characters, however, face it with courage and humour.
• Justice vs. Law: The Thursday Murder Club and police officers Chris and Donna repeatedly bend the rules to achieve what they see as justice. Elizabeth lets Garth go free in exchange for the box; Nina’s arrest is left to the official system. The novel suggests that true justice sometimes operates outside the law.

Epilogue (Chapter 89)

The final numbered chapter is a poignant coda. Stephen’s ashes are placed in the ancient box and flown to Baghdad. Elizabeth plans to travel to Baghdad and Dubai to investigate the Bethany Waites case (a thread from earlier books). Bogdan will redecorate her flat. Mervyn gets his money back but nearly falls for another scam. Ron returns from Copenhagen in a lilac shirt. Ibrahim has supper with Computer Bob. Joyce meets the new resident, Edwin Mayhew (not Mayhem), a retired quantity surveyor.

Joyce reflects on widowhood and the urgency of old age, grateful for the act of writing. She addresses a final note to her late husband Gerry. The book ends with a sense of quiet hope: “peace and weddings,” daffodils, and the miracle of continuing to live.

Reasonable Interpretations

• Elizabeth’s future with grief: The novel suggests she will channel her pain into purpose — travelling the world, solving cases. She is “utterly alone” but also “not alone” because of her friends.
• The box as a symbol: It represents both the destructive power of greed and the possibility of redemption. Sending Stephen’s ashes in it transforms a vessel of crime into a vessel of love.
• Garth’s moral shift: He spares Nina and promises to stop killing. This aligns with Elizabeth’s influence and his grief for Samantha. Whether he truly reforms is left ambiguous.

Six Reader Questions Answered

1. Who killed Kuldesh Sharma?
Nina Mishra, an archaeologist, shot him to steal the ancient box that the heroin was smuggled in. She confessed to Garth in Chapter 84.

2. Why did Elizabeth help Stephen die?
Because Stephen had dementia and chose to end his life with dignity. They had made the agreement together. Elizabeth was present and comforted him.

3. What happened to the ancient box?
After being stolen from the university by Nina, Garth bought it for five million pounds and gave it to Elizabeth. She placed Stephen’s ashes inside and sent it to Baghdad.

4. Did Mitch Maxwell survive?
No. While searching the Tunbridge Wells tip for the box, he suffered a fatal heart attack at the top of a rubbish pile (Chapter 85).

5. Was Joyce telling the truth about throwing the box away?
No. She lied to Mitch and Garth. In Chapter 80 she privately admits the box is still under her sink. Later she hands it over to Elizabeth.

6. What is the significance of the “Code 777” number?
It is a high‑end criminal contact number. Kuldesh’s second phone call on the day of his murder was to Elizabeth’s home — actually to Stephen — using Stephen’s untraceable Code 777 number. This connection helped Elizabeth find the box.
