After a while, I understood him to be depressive. He was asthmatic, he slept poorly, and he complained of insomnia. His work always went slowly, but he said, “Beware of writing that goes fast—that’s a sign it’s probably bad.” He was a man of rules, and his rules kept him alert. “Never allow yourself to be undervalued—why should one be paid less than a great architect, or lawyer, or surgeon?” “Never give a person a second chance,” was another one. “If someone important to you lets you down, you must release them.” Reflecting on Africa, he said, “Hate the oppressor—but fear the oppressed,” a thought he put into his novel.

As for writing: “Always ask yourself, ‘Why am I writing this?’ If you don’t have a good answer, abandon it.” In contrast to this, he also said, “A writer often works toward conclusions of which he is unaware, until he finishes.” Another: “Don’t play with art.” There was no whimsy in Naipaul, no trickery, no artifice, nothing mannered or magical—he hated the conceit in beautiful sentences, he disliked Borges’s stories and most of Faulkner; he admired Richard Jefferies’s style, which he called “brambly.”

His belief, his severity in reading my work (“I warn you, I’m brutal”), his pride in his own work—he truly believed in his gift—helped make me a writer. When my work succeeded, he was proud of me; but he felt that he was poorly represented, that his publisher took him for granted, that in spite of his many prizes and honors his readership was small. With a new agent and different publishers, his fortunes improved. But, with more people listening, he became ever more a provocateur, claiming that women can’t write, that James Joyce is overrated, or that Princess Anne’s daughter had “a criminal face.” In all the obituaries that have been written, there are many instances of these—Vidia’s tantrums and provocations, his outrageous, mood-driven frustrations.

But he knew when he was being irrational or unfair, voicing the darker side of his nature, and, though he disparaged Joyce, he experienced the remorse Joyce called “agenbite of inwit.” One of his favorite writers was Montaigne—indeed, he said, “I am a new man, as Montaigne was a new man.” And he’d read the passage in the essay “On Glory,” where some apt lines occur: “These discourses are, in my opinion, very true and rational; but we are, I know not how, double in ourselves, which is the cause that what we believe we do not believe, and cannot disengage ourselves from what we condemn.”

The death of Pat was a crisis, and within a very short time he broke off relations with his longtime lover, and met and married Nadira Khannum Alvi, who became his lover and protector, housewife, reader, chef, driver, and manager of his literary affairs. After a few misunderstandings, I was sidelined under the rule “Never give anyone a second chance—especially the person who had been loyal.”

Vidia was at last happy at home and still productive. The upshot of our estrangement was that I had a fabulous subject: my thirty-year friendship with him, which I recounted in “Sir Vidia’s Shadow.” It seemed to me a great opportunity, because so many books chronicle love affairs, but how many about friendship, that purer connection, especially one that goes sour?

Ten years passed in silence. At the Hay Festival, I was sitting with Ian McEwan when Naipaul appeared at the door of a big tent, Nadira and her daughter supporting him on each arm as he moved slowly through the gathering, limping, breathing hard.

“Say something to him,” Ian said. I said I didn’t dare. He said, “Go on. Life is too short.”

Provoked, I went up to Vidia and said hello and he took my hand warmly and held on. “I’ve missed you,” I said. He said, “I’ve missed you, too.”

This instance of forgiveness (because my book had been unsparing) is one of the happiest moments of my life. So we reconnected, exchanged letters and phone calls. We met in India and in New York, and, to my great pleasure, Nadira formed a friendship with my wife, Sheila. More than a friendship—they describe themselves as sisters.

A happy ending, for two writers whose work seldom dramatized happy endings.

I especially loved being in India with him, because it was his obsessive subject. But, one day, a strange thing happened. We were being driven to Amber Fort, outside of Jaipur. Vidia looked out the side window as the car was delayed in traffic at a crowded intersection. A small boy, no more than four or five, was seated on a triangular section of broken pavement between two busy roads. The boy was neatly dressed, in a shirt and shorts, cross-legged on a folded square of cloth, at risk amid the confusion of traffic and pedestrians, sadhus, beggars, hawkers with baskets on their head, schoolchildren, bus fumes, pushcarts, motorbikes, and honking horns. The child was animated by the bustle, yet he was alone—no adult near him, no one attending to him.

Naipaul stared sadly at this odd and overlooked boy, and studied the scene for a long moment. As our car began to move on, he said to me, “I see myself in that child.”
