No, he mustn’t think about it, or indeed about anything, and especially not about heroin, because heroin was the only thing that really worked, the only thing that stopped him scampering around in a hamster’s wheel of unanswerable questions. Heroin was the cavalry. Heroin was the missing chair leg, made with such precision that it matched every splinter of the break. Heroin landed purring at the base of his skull, and wrapped itself darkly around his nervous system, like a black cat curling up on its favourite cushion. It was as soft and rich as the throat of a wood pigeon, or the splash of sealing wax onto a page, or a handful of gems slipping from palm to palm.

The way other people felt about love, he felt about heroin, and he felt about love the way other people felt about heroin: that it was a dangerous and incomprehensible waste of time. What could he say to Debbie? ‘Although you know that my hatred for my father, and my love for drugs, are the most important relationships in my life, I want you to know that you come in third.’ What woman would not be proud to be ‘among the medals’ in such a contest?

‘Oh, for fuck’s sake shut up,’ mumbled Patrick out loud, drinking his second dry martini with as little restraint as the first. If things went on this way he would have to call Pierre, his truly wonderful New York dealer. No! He wasn’t going to do it, he had sworn that he wasn’t going to do it. 555–1726. The number might as well have been tattooed on his wrist. He hadn’t rung it since September, eight months ago, but he would never forget the bowel-loosening excitement of those seven digits.

Golden Grapes was back, peeling the heavy yellow lead from the neck of the Corton Charlemagne, and cradling the bottle of claret, while Patrick studied the picture of a white chateau under a flat gold sky. Perhaps with these consolations he would not have to score after dinner, thought Patrick sceptically, sucking a sample of Corton Charlemagne into his mouth.

The first taste made him break into a grin of recognition, like a man who has sighted his lover at the end of a crowded platform. Raising the glass again, he took a large gulp of the pale yellow wine, held it in his mouth for a few seconds, and then let it slide down his throat. Yes, it worked, it still worked. Some things never let him down.
