"Moberg was a degenerate. He was small, with thin blond hair and a face that was pale and flabby. I have never seen a man so bent on self-destruction — not only self, but destruction of everything he could get his hands on. He was lewd and corrupt in every way. He hated the taste of rum, yet he would finish a bottle in ten minutes, then vomit and fall down. He ate nothing but sweet rolls and spaghetti, which he would heave the moment he got drunk. He spent all his money on whores and when that got dull he would take on an occasional queer, just for the strangeness of it. He would do anything for money, and this was the man we had on the police beat. Often he disappeared for days at a time. Then someone would have to track him down through the dirtiest bars in La Perla, a slum so foul that on maps of San Juan it appears as a blank space. La Perla was Moberg's headquarters; he felt at home there, he said, and in the rest of the city — except for a few horrible bars — he was a lost soul.
He told me that he'd spent the first twenty years of his life in Sweden, and often I tried to picture him against a crisp Scandinavian landscape. I tried to see him on skis, or living peacefully with his family in some cold mountain village. From the little he said of Sweden I gathered he'd lived in a small town and his parents had been comfortable people with enough money to send him to college in America.
He spent two years at NYU, living in the Village at one of those residence hotels that cater to foreigners. This apparently unhinged him. Once he was arrested on Sixth Avenue, he said, for pissing on a fireplug like a dog. It cost him ten days in the Tombs, and when he got out he left immediately for New Orleans. He floundered there for a while, then got a job on a freighter headed for the Orient. He worked on boats for several years before drifting into journalism. Now, thirty-three years old and looking fifty, his spirit broken and his body swollen with drink, he bounced from one country to another, hiring himself out as a reporter and hanging on until he was fired.
Disgusting as he usually was, on rare occasions he showed flashes of a stagnant intelligence. But his brain was so rotted with drink and dissolute living that whenever he put it to work it behaved like an old engine that had gone haywire from being dipped in lard."
