Gabriel's Moon

In 1936, six-year-old Gabriel Dax depends on a glass moon-globe night light to fall asleep at Yeomanswood Farm in Oxfordshire. His mother, Rosalind, lights it each evening and promises that one day they will all be together "on the moon" with his father, who died in a plane crash in Persia when Gabriel was two. One night Gabriel wakes to smoke and flames. He finds his mother lying dead in the drawing room, escapes through a kitchen window by smashing the latch with a telephone receiver, and hides behind the fish pond as the house burns. His older brother, Sefton, is safe at boarding school. The fire brigade concludes that the night light caused the blaze.

Twenty-four years later, in August 1960, Gabriel is a travel writer living in Chelsea. Through his friend Thibault N'Danza, now a government minister in the newly independent Congo, he secures an exclusive tape-recorded interview with Prime Minister Patrice Lumumba in Léopoldville (present-day Kinshasa). Lumumba confides that President Eisenhower and others want him dead, naming three people involved in the plot: Hillcrest, someone whose name sounds like "Sykes," and Dupetit. On the flight home, Gabriel notices a woman in first class reading his book Dictatorland.

Back in London, Gabriel finds signs that someone has searched his flat. His Lumumba article is accepted by the newspaper's foreign editor but never published, deemed irrelevant after a coup by Colonel Mobutu. In January 1961, the woman from the plane introduces herself as Faith Green in a Chelsea café and tells Gabriel that Lumumba has been shot by firing squad. She works for MI6's Institute of Developmental Studies, a unit that hunts traitors within British intelligence. She knows Sefton, who works at the Foreign Office, and knows Gabriel performs occasional courier tasks for him. She asks Gabriel to travel to Spain to buy a drawing from a fading surrealist artist named Blanco. Gabriel refuses at first but eventually accepts, drawn by the pay and by Faith's compelling authority.

Around the same time, Gabriel begins psychoanalysis with Katerina Haas, a German analyst in Hampstead, seeking help for chronic insomnia that has plagued him since the fire. Haas introduces the concept of anamnesis, the recovery of forgotten memories, and urges Gabriel to investigate the night of the fire.

Using his uncle Aldous Dax, a retired art dealer, as cover, Gabriel flies to Madrid, drives to Cádiz, and buys a drawing from Blanco. He delivers it to Kit Caldwell, MI6's head of station in Madrid and a former lover of Blanco. Gabriel meets Nancy-Jo Berndlinger, a young American art student who asks him to carry a parcel back to London. At the airport, he opens it, finds heroin, and disposes of the drugs moments before police search his luggage. Nancy-Jo confesses she was coerced by a CIA operative using the alias "Raymond Queneau," who orchestrated the trap to gain leverage over the Lumumba tapes. Shortly after, Nancy-Jo is found dead of an apparent overdose. Gabriel suspects Queneau killed her.

Gabriel buries the tapes beneath a holly bush in his garden and tells Faith they are in a bank vault with instructions to release them if anything happens to him. Queneau confronts Gabriel, confirming that the names on the tapes link to Eisenhower. Gabriel lies, claiming he erased them.

Pursuing anamnesis, Gabriel tracks down Manley Dryden, the retired loss adjuster who investigated the Yeomanswood fire. Dryden reveals that a 999 emergency call was made from inside the house and that three empty bottles of Serenital, a powerful tranquilizer, were found in the family refrigerator. His original report concluded that the fire was caused not by the night light but by Rosalind, who was incapacitated by Serenital and alcohol. Gabriel is shaken by the implication that his mother may have deliberately set the fire.

In early 1962, Faith sends Gabriel back to Cádiz for a second drawing. At Blanco's studio, the artist demands payment for a "secret": Caldwell visited him, confessed to being a Soviet agent, and proposed they defect together to Moscow. Gabriel reports this to Faith, who dispatches her team. At a Cádiz hotel, Gabriel discovers Sefton in the lobby alongside Faith and Institute colleagues Harrison Lee and Anatoly Sirin. The revelation that his brother has been secretly working with the Institute ignites a fury that overrides all loyalty. Gabriel warns Caldwell of the betrayal and drives him to the port that night, helping him board a Polish freighter.

The defection becomes a public scandal. Gabriel feels no guilt and channels his energy into his book. Obsessed with Faith, he hires Tyrone, the locksmith brother of his girlfriend Lorraine Rogan, to follow her to a holiday bungalow in Southwold, Suffolk. Faith discovers Gabriel nearby and invites him in. They sleep together. Gabriel notices small white scars on her skin: cigarette burns from Gestapo torture in 1944, when she served in the Special Operations Executive (SOE), Britain's wartime covert-operations service. Faith reveals that Eisenhower authorized Lumumba's assassination, that "Sykes" was her own cover name in Léopoldville, and that she alerted the CIA when Lumumba tried to escape, leading to his execution. When Gabriel returns to London, the tapes have been dug up from beneath his holly bush.

Faith then reframes everything: Caldwell's defection was staged. Discovered as a Soviet agent in 1940, he was turned back to the British side and spent decades feeding controlled information to Moscow. Gabriel's role in the "escape" was part of Faith's plan all along. She also announces her engagement. Faith asks Gabriel to deliver another Blanco drawing to Warsaw; he agrees but insists on a weapon, receiving a tiny automatic pistol called a Baby Browning. In a crowded Warsaw dentist's waiting room, Caldwell explains that the drawings contain microdots, microscopic texts hidden in the dedications, used to pass misleading intelligence to the KGB. He gives Gabriel a book of matches containing coded numbers that identify a mole within British intelligence.

Fleeing Warsaw by car, Gabriel catches a ferry from Cuxhaven to England. On the dark rear deck, Queneau appears with a gun, revealing that three people heard the names on the Lumumba tapes and two are already dead. Gabriel realizes Queneau is Hillcrest, Eisenhower's link to the assassination plot. As Queneau raises his weapon, Gabriel fires the Baby Browning through his coat pocket, wounds him, and tips him overboard into the North Sea.

Faith collects the coded matchbook and asks Gabriel to observe whether someone in Battersea Park uses the word "refulgent." The person who arrives is Sefton. He uses the word. Gabriel warns him: "I think they're on to you." Panicked, Gabriel flees to Rome. Days later, Sefton's wife, Victoria, calls to say Sefton has been found hanged from his garden pergola by his son, Cyril. At the funeral, Faith reveals that the matchbook identified Sefton as a Soviet mole recruited for money in Geneva. Sefton had begun questioning Caldwell's loyalty, making his exposure urgent. Faith also reveals that Sefton originally proposed Gabriel as a courier and that nothing in their relationship was coincidental. When Gabriel declares he is done, Faith replies that nobody quits. A Russian cultural attaché then approaches Gabriel with £1,000, payment from the KGB for his supposed role as Caldwell's contact. Gabriel keeps the money, knowing that rejecting it could endanger Caldwell.

In January 1963, in a session with Katerina Haas, Gabriel articulates what he truly wants: to love someone unreservedly, identifying Faith as that person. Standing on the Tube platform at Covent Garden, overwhelmed by longing, he turns to leave. Someone gently takes his hand. He turns to see Faith's pale face, smiling at him.
