Fifty feet away to Laing's left a cocktail party was in progress. Two buffet tables covered with white cloths had been laid with trays of canapés and glasses, and a waiter was serving drinks behind a portable bar. Some thirty guests in evening dress stood about talking in small groups. For a few minutes Laing ignored them, absent-mindedly tapping his rackets case on the parapet, but something about the hard, over-animated chatter made him turn. Several of the guests were looking in his direction, and Laing was certain that they were talking about him. The party had moved nearer, and the closest guests were no more than ten feet away. All were residents from the top three floors. Even more unusual was the self-conscious formality of their dress. At none of the parties in the high-rise had Laing seen anyone dressed in anything other than casual wear, yet here the men wore dinner-jackets and black ties, the women floor-length evening dresses. They carried themselves in a purposeful way, as if this were less a party than a planning conference.
Almost within arm's reach, the immaculate figure of a well-to-do art dealer was squaring up to Laing, the lapels of his dinner-jacket flexing like an over-worked bellows. On either side of him were the middle-aged wives of a stock-exchange jobber and a society photographer, staring distastefully at Laing's white sports-clothes and sneakers.
Laing picked up his rackets case and towel bag, but his way to the staircase was blocked by the people around him. The entire cocktail party had moved along the roof, and the waiter now stood alone between the bar and the buffet tables.
Laing leaned against the parapet, for the first time conscious of the immense distance to the ground below. He was encircled by a heavily breathing group of his fellow residents, so close that he could smell the medley of expensive scents and after-shaves. He was curious as to what exactly they were going to do, but at the same time was aware that at any moment a meaningless act of violence might occur.
"Dr Laing… Ladies, would you release the doctor?" At what seemed the last moment, a familiar figure with adroit hands and a soft walk called out reassuringly. Laing recognized the jeweller whose hysterical wife he had briefly examined during the power failure. As he greeted Laing the guests casually dispersed, like a group of extras switched to another scene. Without thinking, they strolled back to their drinks and canapés.
"Was it fortunate that I arrived?" The jeweller peered at Laing, as if puzzled by his presence in this private domain. "You're here to play squash with Anthony Royal? I'm afraid he's decided to decline." He added, as much to himself as to Laing, "My wife should have been here. She was treated appallingly, you know-they were like animals…"
Slightly shaken, Laing accompanied him to the stairway. He looked back at the cocktail party, with its well-bred guests, uncertain whether he had imagined the imminent attack on him. After all, what could they have actually done-hardly tossed him over the edge?
As he pondered this, he noticed a familiar pale-haired figure in a white safari-jacket standing with one hand on the callisthenics machine in the penthouse overlooking the northern end of the roof. Resting at his feet was Royal's alsatian with its arctic coat, without doubt the premier dog in the high-rise. Making no attempt to hide himself, Anthony Royal was watching Laing with a thoughtful gaze. As always, his expression was an uneasy mixture of arrogance and defensiveness, as if he were all too aware of the built-in flaws of this huge building he had helped to design, but was determined to outstare any criticism, even at the price of theatrical gestures such as the alsatian and his white-hunter's jacket. Although he was over fifty, his shoulder-length fair hair made him look uncannily youthful, as if the cooler air at these great heights had somehow preserved him from the ordinary processes of ageing. His bony forehead, still marked by the scars of his accident, was tilted to one side, and he seemed to be checking that an experiment he had set up had now been concluded.
Laing raised one hand and signalled to him as the jeweller ushered him briskly below, but Royal made no reply. Why had he not cancelled their squash game by telephone? For a moment Laing was certain that Royal had deliberately let him come up to the roof, knowing that the party was in progress, simply out of interest in the guests' reactions and behaviour.
The next morning Laing rose early, eager to get on. He felt fresh and clear-headed, but without realizing why he decided to take the day off. Promptly at nine, after pacing about for two hours, he telephoned his secretary at the medical school and postponed that afternoon's supervision. When she expressed regret at Laing's illness he brushed this aside. "It's all right, I'm not ill. Something important has come up."
What? Puzzled by his own behaviour, Laing wandered around the small apartment. Charlotte Melville was also at home. She was dressed for the office in a formal business suit, but made no attempt to leave. She invited Laing over for coffee, but when he arrived an hour later she absent-mindedly handed him a glass of sherry. His visit, Laing soon discovered, was a pretext for him to examine her son. The boy was playing in his room, but according to Charlotte was not feeling well enough to go to the junior school on the 10th floor. Annoyingly, the young sister of an airline pilot's wife on the 1st floor had declined to baby-sit.
"It's a nuisance, she's usually only too keen. I've relied on her for months. She sounded rather vague on the phone, as if she was being evasive…"
Laing listened sympathetically, wondering whether he should volunteer to look after the child. But there was no hint of this in Charlotte's voice. Playing with the boy, Laing realized that there was nothing wrong with him. Lively as ever, he asked his mother if he could go to his 3rd-floor playgroup that afternoon. Without thinking, she refused. Laing watched her with growing interest. Like himself, Charlotte was waiting for something to happen.
They did not have long to wait. In the early afternoon the first of a fresh series of provocations took place between the rival floors, setting in motion again the dormant machinery of disruption and hostility. The incidents were trivial enough, but Laing knew already that they reflected deep-rooted antagonisms that were breaking through the surface of life within the high-rise at more and more points. Many of the factors involved had long been obvious-complaints about noise and the abuse of the building's facilities, rivalries over the better-sited apartments (those away from elevator lobbies and the service shafts, with their eternal rumbling). There was even a certain petty envy of the more attractive women who were supposed to inhabit the upper floors, a widely held belief that Laing had enjoyed testing. During the electricity blackout the eighteen-year-old wife of a fashion photographer on the 38th floor had been assaulted in the hairdressing salon by an unknown woman. Presumably in retaliation, three air-hostesses from the 2nd floor were aggressively jostled by ta party of marauding top-floor matrons led by the strong-shouldered wife of the jeweller.
Watching from Charlotte's balcony, Laing waited as the first of these incidents took place. Standing there with a pretty woman, a drink in one hand, he felt pleasantly light-headed. Below them, on the 9th floor, a children's party was in full swing. The parents made no attempt to restrain their offspring, in effect urging them to make as much noise as possible. Within half an hour, fuelled by a constant flow of alcohol, the parents took over from their children. Charlotte laughed openly as soft drinks were poured on to the cars below, drenching the windscreens and roofs of the expensive limousines and sports saloons in the front ranks.
