this when he returned that evening from the medical school. By six o'clock the section of the parking-lot reserved for the 20th to the 25th floors would usually be full, forcing him to leave his car in the visitors' section three hundred yards from the building. Reasonably enough, the architects had zoned the parking-lots so that the higher a resident's apartment (and consequently the longer the journey by elevator), the nearer he parked to the building. The residents from the lower floors had to walk considerable distances to and from their cars each day-a sight not without its satisfaction, Laing had noticed. Somehow the high-rise played into the hands of the most petty impulses.
That evening, however, as he reached the already crowded car-park, Laing was surprised by his fellow tenants' tolerant behaviour. He arrived at the same time as his neighbour Dr Steele. By rights they should have raced each other for the last vacant place, and taken separate elevators to their floor. But tonight each beckoned the other forward in a show of exaggerated gallantry and waited while the other parked. They even walked together to the main entrance.
In the lobby a group of tenants stood outside the manager's office, remonstrating noisily with his secretary. The electrical supply system on the gth floor was still out of order, and at night the floor was in darkness. Fortunately it was light until late in the summer evening, but the inconvenience to the fifty residents on the floor was considerable. None of the appliances in their apartments would function, and the limits of co-operation with their neighbours on the floors above and below had soon been reached.
Steele watched them unsympathetically. Although he was in his late twenties, his manner was already securely middle-aged. Laing found himself fascinated by his immaculate centre parting, almost an orifice.
"They're always complaining about something," Steele confided to Laing as they stepped into an elevator. "If it isn't this, it's that. They seem unwilling to accept that the services in a new building take time to settle down."
"Still, it must be a nuisance to have no power."
Steele shook his head. "They persistently overload the master-fuses with their elaborate stereo-systems and unnecessary appliances. Electronic baby-minders because the mothers are too lazy to get out of their easy chairs, special mashers for their children's food..."
Laing waited for the journey to end, already regretting his new-found solidarity with his neighbour. For some reason, Steele made him nervous. Not for the first time, he wished he had purchased an apartment above the 30th floor. The high-speed elevators were bliss.
"The children here look well enough to me," he remarked when they stepped out at the 25th floor.
The surgeon held his elbow in a surprisingly powerful grip. He smiled reassuringly, flashing a mouth like a miniature cathedral of polished ivory.
"Believe me, Laing. I see their teeth."
The punitive tone in Steele's voice, as if he were describing a traditionally feckless band of migrant workers rather than his well-to-do neighbours, came as a surprise to Laing. He knew casually a few of the 9th floor residents-a sociologist who was a friend of Charlotte Melville's, and an air-traffic controller who played string trios with friends on the 25th floor, an amusing and refined man to whom Laing often talked as he carried his cello into the elevator. But distance lent disenchantment.
The extent of this separation of loyalties was brought home to Laing when he set off to play squash with Anthony Royal. He took an elevator up to the 40th floor and, as usual, arrived ten minutes early so that he could go out on to the roof. The spectacular view always made Laing aware of his ambivalent feelings for this concrete landscape. Part of its appeal lay all too clearly in the fact that this was an environment built, not for man, but for man's absence.
Laing leaned against the parapet, shivering
