Later, as he sat on his balcony eating the dog, Dr Robert Laing reflected on the unusual events that had taken place within this huge apartment building during the previous three months.
Now that everything had returned to normal, he was surprised that there had been no obvious beginning, no point beyond which their lives had moved into a clearly more sinister dimension.
With its forty floors and thousand apartments, its supermarket and swimming-pools, bank and junior school – all in effect abandoned in the sky – the high-rise offered more than enough opportunities for violence and confrontation. Certainly his own studio apartment on the 25th floor was the last place Laing would have chosen as an early skirmish-ground. This over-priced cell, slotted almost at random into the cliff face of the apartment building, he had bought after his divorce specifically for its peace, quiet and anonymity. Curiously enough, despite all Laing’s efforts to detach himself from his two thousand neighbours and the regime of trivial disputes and irritations that provided their only corporate life, it was here if anywhere that the first significant event had taken place – on this balcony where he now squatted beside a fire of telephone directories, eating the roast hind-quarter of the alsatian before setting off to his lecture at the medical school.
While preparing breakfast soon after eleven o’clock one Saturday morning three months earlier, Dr Laing was startled by an explosion on the balcony outside his living-room. A bottle of sparkling wine had fallen from a floor fifty feet above, ricocheted off an awning as it hurtled downwards, and burst across the tiled balcony floor.
