Ionce knew a man whose remarkable lying caused me to overlook him. When we met, I was nineteen and world-weary, and he fit a mold I thought I knew: rich (he’d attended Harrow, a particularly expensive private school), clever (then Oxford, early), seemingly conservative (a link to the army). A few years later, I crossed paths with him again when I was thinking of moving into a cheap room in a house in London occupied by a woman he was dating. The room was in the eaves, and I took it, even though it didn’t have a door—just a permanently open trap with a ladder leading in.

At that time, the man worked for the civil service. He was writing a satire about it, he said. He would come to our house with a big army bag slung over his shoulders, and through the square hole in my floor I’d hear him talking about the Grenadier Guards, Afghanistan, P.T.S.D. I paid him little attention, but I knew that class was a constant source of stress in his relationship with my housemate, whom I’ll call Sophie. He had a string of names and well-known relations; he introduced himself as the son of a lord. She was middle class. Sometimes, the liar would go to extravagant parties and not invite her, and she would feel insufficiently impressive.

When Sophie, who had become dissatisfied with her job, applied for a position with the intelligence services, he encouraged her. But then she told him that she’d listed his name on a questionnaire—the sort designed to reveal anything in her private life that might compromise her, Queen, or country—and he said that there was no need to mention him. Days later, he broke things off. Sophie was shocked and upset, and grew more so when, shortly after that, she received a text message from the interviewer to whom she had spoken, meant for someone else. “It’s all a tissue of lies,” it read. “No Grenadier Guards. No Harrow. Nothing.”

The phrase “tissue of lies,” like “web” and “fabrication,” evokes the warp and weft of a narrative woven largely from threads of untruth—its sometimes animal vitality. Since then, I’ve thought often about how to retell the story of the liar. Relating it to friends as an anecdote was to submit to its surreal quality. It didn’t feel entirely right when I told it that way, given the license for exaggeration that the anecdote form allows. Doing so seemed to enact a kind of indulgent dynamic that I associate with ghost tours and urban myths of baby alligators living in sewers, or viral videos of shrouded figures walking across doorways. When I began to write fiction, I considered using the story but felt that it was unsuitable—both implausible and, somehow, too obvious. The parts that were most shocking in real life—the secret services, the texted tricolon, the degree to which he inflated his imaginary aristocratic heritage—would read as clichéd plot devices. But, over the years, the story kept hopping into my mind. When I encountered lies in my own life or in the news—reading about British undercover officers infiltrating the climate movement, for example, using the identities of dead babies and fathering children with activists—I would find the story of Sophie’s liar sitting there underneath, a toad under a pile of leaves.

Perhaps the reason that the liar has stayed with me has something to do with his simultaneous brazenness and banality—though the revelation was shocking, he himself had registered so little with me, and the fact of being lied to seemed, in the end, almost pedestrian. Lies are ubiquitous; in a certain light, to be shocked by them seems precious.

Such is the posture assumed by the Spanish novelist Juan Jacinto Muñoz-Rengel in “A History of Lying,” a book-length essay in which he declares that “the history of humankind is nothing other than the history of making it up.” Best known for a parodic crime novel titled “The Hypochondriac Hitman” and other postmodern experiments with literary convention, Muñoz-Rengel sets out from a brief summary of Cartesian doubt (which, he says, none of the philosophical solutions that have been proposed properly resolve) to argue that lying is not, as conventional morality might have us assume, a practice to be avoided whenever possible but, rather, an innate and inevitable element of language and life.

Muñoz-Rengel marshals a wide range of examples to this end, beginning with that of the Cretan seer Epimenides, who rose from a deep sleep in the sixth century B.C. to declare that “all Cretans are liars,” and stretching to the present day, when Spotify’s sharing function allows people to “stop listening to the things they want to and begin prioritising instead the image of themselves.” Skimming the surface of philosophy (Nietzsche, Freud, Ferdinand de Saussure, and post-structuralists are all praised for their skepticism), Muñoz-Rengel also attempts to give his polemic a scientific varnish by referring to the natural world. The book is laced with nuggets of evolutionary biology and examples of animals with the ability to disguise themselves. Consider the cuttlefish, he writes, for whom deception is a biological strategy. It can not only change color but is also “capable of modifying its texture, the entirety of its external structure, and even of generating patterns similar to the shifting seabed, which it can then set in motion along its body in the opposite direction to that in which it is actually moving.”

The example does much to illustrate the breadth of Muñoz-Rengel’s definition of a lie, as well as his subsequent tendency to blur concrete details, as well as historical fact, in service of his theory. So broad is his lens that people captured and enslaved by the Phoenicians are described as “overly trusting foreigners—the more credulous kind, who probably hung around the bait, rather than withdrawing somewhere safe.” Even his less extreme conflations are absurd. “Having dealings with other people means staying in a constant state of dissimulation,” he writes—in other words, you lie whenever you are polite. Gone are the important distinctions—based on their scale and severity, their effects and their motivations—between individual lies. And who would hold a single cuttlefish to be an example of deceitful behavior, when its aptitude for concealment is helpful to its survival?

Some of the most exaggerated portions of Muñoz-Rengel’s book are those in which he claims that, because language uses signs to represent real things, it, too, is a sort of deception, and that all understandings reached through metaphors are therefore “based on speculation, projection, lies.” This, again, seems to elide crucial nuances. While metaphors can sometimes be misleading, they can also illuminate the speaker’s personal response to a subject. In neither case do they impart knowledge that is empirically falsifiable, as lies do. When I compared the story of the liar to a toad buried in leaf litter, I was not claiming that the story had literally been hibernating for the winter—grayish, warty—then sprung out when it was unexpectedly disturbed, an unwelcome, grotesque, vaguely comic creature. I was trying to convey something of the particular way the story had lodged itself in my mind and, even when I forgot about it, seemed to be leading a life of its own.

Sometimes, among all Muñoz-Rengel’s vague tracings of unreality, I detect something sincere. His fierce allegiance to the idea that the origins of lying reside in any detachment from reality brings to mind the idea of not lying as an active pursuit, which takes the form of a constant sifting through the details of life, and a simultaneous attempt to articulate them as clearly as possible—something akin to producing art. But when he writes off representation with such little regard for the distinction between it and intentional lying, it comes—gradually, frustratingly—to seem as if he is not so much making a case about the inevitability of epistemological carelessness as providing a demonstration of it.

Ican’t pretend his lying hasn’t made the liar I knew more interesting, but more interesting still was how, around him, the world behaved in unlikely ways. Like Boris Johnson—who was described by one former Tory M.P., himself often denying having been in the intelligence services, as “the best liar we’ve ever had”—the liar told stories that were superficially entertaining but predictable, and used them to garner power.

The propulsive force of people who know how to gain trust by knitting improbable tales is Muñoz-Rengel’s most generative subject. He recounts the story of the Catalan man Joan Pujol, who, in 1941, approached the British authorities to offer his services as a spy. By his own account, Pujol—whose family suffered during the Spanish Civil War, and who consequently hated Fascism and Communism both—came to spying in a roundabout way:

I was managing a poultry farm. . . . The poultry farm was not a success. . . . I decided to “exit” from the stage, as they say in the theatre. . . . My life in Madrid as a hotel manager began peacefully enough. . . . On 3 September 1939 England had declared war on Germany. . . . My humanist convictions would not allow me to turn a blind eye to the enormous suffering that was being unleashed by this psychopath Hitler.

When the English rejected him, Pujol instead applied to work for the Germans, who, unsuspecting, took him on and assigned him a mission to Britain. Pujol, who had no intention of spying for them (he later claimed that he planned to work as a double agent), told his handlers that he was moving to Lake Windermere. Instead, he and his wife, whom he married in Madrid, had moved to Lisbon, where he bought a British guidebook, railway timetable, and map, and began to send made-up reports to his employer, accompanied by expense invoices. In April, 1942, the Allies signed Pujol on as a double agent, code-named Garbo. Over the next two years, he wove “a network of completely fictitious sub-agents”—twenty-seven in total—who all needed paying. His inventions included a Brit of Swiss-German descent named William Gerbers, a Welsh nationalist named Dagobert, a Gibraltarian waiter living in Chislehurst, and a Venezuelan student in Glasgow (and his brother, whom Pujol named Moonbeam). Their invented efforts led to Pujol charging the Nazis a fortune. Sometimes, when the Germans wondered why Pujol’s sources failed to file reports until after the fact, he made up stories of illness or told them that the source had died, leaving behind a fictional widow who needed the money.

In 1943, Pujol was enlisted to convince the Germans that the Allies were planning an invasion of the Pas-de-Calais, rather than Normandy. He kept up the lie until the last moment, when it was too late for the Germans to stop the D Day landings. By then, he and his wife and first child had been relocated to London, where the couple had a second baby. Declassified M.I.5 files show that, at the time, his wife was so homesick (she especially missed her mother) that she threatened to expose Pujol to the Germans. To keep her silent, Pujol and his British handler tricked her into believing that her behavior had led to his imprisonment, and arranged for her to visit a detention center, where Pujol pretended to be incarcerated. The Allies helped him maintain his cover throughout the war (and even after); he was both awarded an Iron Cross by Hitler and made an M.B.E. by King George VI—after which he faked a bout of malaria, and sloped off to Venezuela, where he opened a bookshop.

Pujol’s story only became known publicly in 1984, when an author named Nigel West went on a mission to uncover Garbo’s true identity: the result was a book, “Operation Garbo,” co-written with Pujol and published in 1985. (Although Pujol used his real name, “Nigel West” is a pseudonym for Rupert Allason, a former Conservative M.P. who has written about espionage, and has published several crime novels.) In “Operation Garbo,” Pujol is a lavish narrator, alert to the possibilities of storytelling even in his everyday life. When meeting his Nazi handler, he wonders whether he was taken on because this handler was “intoxicated by my verbosity.”

Muñoz-Rengel approves of Pujol for his “capacity for artifice,” which he used to fight against injustice “without firing a single bullet.” (None of Pujol’s wife’s role or treatment appears in the book, and one has the sense that Muñoz-Rengel is captivated by Pujol’s madcap behavior, rather than curious about its roots or its implications for the people who knew him.) Muñoz-Rengel attributes West’s success at tracking down Pujol in part to his vocation, writing that “novelists understand better than anyone the fictional nature of reality.” If there is an optimistic proposition in Muñoz-Rengel’s book, it is the idea that such an awareness grants you a special kind of agency. Once one knows that “everything” is a lie, one is no longer “some unsuspecting sap” but instead becomes “an actor who has chosen to act.” What this agency grants the person who wields it is not clear, but Muñoz-Rengel emphasizes that it is through art—“a sublime kind of deceit”—that one can obtain it. Cubists, for example, ditched the “fleeting lie” of classical beauty, and Dadaists broke with “the dominion of logic.” Conceptual art draws the viewer “into a game of reinterpretation and construction about what is real.”

It’s a shame that Muñoz-Rengel doesn’t connect these musings to his own work as a fiction writer. His account suggests a unidirectional process of unsettling that emanates from the artist into the world. But invention can also lead artists to unearth experience that was unadmitted to themselves. I write fiction partly to work out what I skate over and keep secret from myself; it’s difficult to start without something that feels real, a solid platform on which to stand. After that, it’s stimulating to stitch artifice and reality into a performance—a lie that lets someone in. Sketching out the relationship of truth and falsehood in Muñoz-Rengel’s own process might have offered the reader a foothold in the shifting sands of his argument, and an example of the kind of liberation and agency that he claims to value.

After Sophie learned that her boyfriend wasn’t the person he claimed to be—he had cribbed aristocratic middle names from fiction and an adopted forebear, had not obtained his undergraduate education early at Oxford, and so on—I did not see him for years. I drifted away from our shared friends, whom I hadn’t told what I knew. In our post-university social universe, personal and professional connections were difficult to disentangle, and there seemed to be a violence in puncturing their relationships and confronting them—him, too—with the truth. I had the opportunity to expose him to them, and I decided not to take it.

Still, I heard things about him from this or that person from time to time. One said that his age was different depending on whom you asked. Another maintained that he had tried to warn Sophie by recommending Graham Greene’s novel “England Made Me,” in which the protagonist pretends to have gone to Harrow and goes on lying from there. One night, I saw him at a bachelorette party. At the end of the evening, he was met by a willowy blond woman, a celebrity whose face I knew from science-fiction and period dramas—another notch in the story that seemed to me, in the days and years after, so implausible it was like a narrative contagion.

I sometimes wonder whether, in the end, not telling friends about the liar wasn’t so much an act of gentleness but an avenue to power. If the liar felt that he had a nice view over the people in his life—knowing more, seeing more—then I was there, watching them all, from a little higher up. It can be intoxicating to watch someone turn themselves into a character when you can see the color and the construction of the work. Nowadays, the liar works in tech, occasionally writes articles, and appears in front of governmental bodies.

Whenever I see her, Sophie and I add something that we’ve heard to the story of the liar, reframing the tale with new information, joking darkly about the latest development—it doesn’t look like the story is about to end. It’s not that Sophie hasn’t moved on. It’s not that the liar was particularly magnetic or charismatic. It’s that his lies made her marginal, and reduced their relationship to petrol fumes, and we want to make it solid again. Perhaps in using words carefully, placing the events in relation to other facts, and admitting how much we don’t know, Sophie and I run the risk of being overly literal, but I don’t think so. When the truth is strange, telling the story to each other—a version of it that incorporates both the plotline he wanted us to inhabit and our own experiences—is a way of showing how much life is driven by fiction, and then of weaving that fiction back into the real world, where it belongs. ♦
