It was really unbearable to contemplate being separated from the coke for so long, but he couldn’t control himself if he carried supplies with him. The sensible thing to do was to prepare a couple of fixes, one in the rather tired old syringe he had been using all night, its rubber plunger now tending to stick to the sides of the barrel, and the other in the precious untouched syringe. Just as some men wore a handkerchief in their breast pockets to cope with the emergency of a woman’s tears, or a sneeze, he often tucked away a couple of syringes into the same pocket to cope with the endlessly renewed emptiness that invaded him. Pip! Pip! Be prepared!

Suffering from yet another aural hallucination, Patrick overheard a conversation between a policeman and a member of the hotel staff.

‘Was this guy a regular?’

‘Na, he was the holiday-of-a-lifetime type.’

‘Ya, ya,’ muttered Patrick impatiently. He wasn’t that easily intimidated.

He put on a clean white shirt, slipped into his second suit, a dark grey herringbone, stepping into his shoes at the same time as he did up his gold cufflinks. His silver and black tie, unfortunately the only one he had, was flecked with blood, but he managed, by tying it rather too short, to disguise the fact, although he had to tuck the longer strip into his shirt, a practice he despised.

Less easily solved was the problem of his left eye, which had now completely closed, except for an occasional nervous fluttering. He could, with great effort, open it up but only by raising his eyebrows to a position of high indignation. On his way to the Key Club, he would have to go to the pharmacy and get himself an eyepatch.

His breast pocket was deep enough to conceal the raised plungers of the two syringes, and the bag of smack fitted neatly into the ticket pocket of his jacket. Everything was completely under control, except that he was sweating like a stuck pig and couldn’t shake off the sense that he had forgotten something crucial.

Patrick took the chain off the door and glanced back nostalgically at the fetid dark chaos he was leaving behind. The curtains were still closed, the bed unmade, pillows and clothes on the floor, the lamp overturned, the trolley of food rotting in the warm atmosphere, the bathroom flooded and the television, where a man was shouting, ‘Come to Crazy Eddie’s! The prices are insane,’ still flickering.

Stepping out into the corridor, Patrick could not help noticing a policeman standing outside the next-door room.

His overcoat! That was what he had forgotten. But if he doubled back wouldn’t it look guilty?

He hovered in the doorway, and then muttered loudly, ‘Oh yes, I must . . .’ drawing the policeman’s attention to himself as he strode back appalled into his room. What were the police doing there? Could they tell what he’d been doing?
