Shortly before dawn Wilder found himself in an empty apartment on the 26th floor. Once occupied by a woman and her small son, the apartment had recently been abandoned, and no attempt had been made to padlock the door from the outside. Tired after the night's rampage, Wilder wasted no time in breaking down the door. He had side-stepped his raiding party, leaving them to break up Talbot's apartment for the tenth time. During these last minutes of darkness he would settle himself into an empty apartment, and sleep through the long hours of daylight in time to resume his ascent of the high-rise at dusk.

Wilder moved around the three rooms, satisfying himself that no one was hiding in the kitchen or bathroom. He wandered about in the darkness, kicking open the cupboards and knocking any books or ornaments to the floor. Before leaving, the owner had made a half-hearted attempt to tidy the apartment, packing away the child's toys in a bedroom wardrobe. The sight of the freshly swept floors and neatly furled curtains unsettled Wilder. He pulled the drawers on to the floor, heaved the mattresses off the beds, and urinated into the bath. His burly figure, trousers open to expose his heavy genitalia, glared at him from the mirrors in the bedroom. He was about to break the glass, but the sight of his penis calmed him, a white club hanging in the darkness. He would have liked to dress it in some way, perhaps with a hair-ribbon tied in a floral bow.

Now that he was alone Wilder felt confident of his progress. His hunger was overlaid by his feelings of triumph at having climbed more than half-way up the high-rise. From the windows the ground below was barely visible, part of a world he had left behind. Somewhere above him, Anthony Royal was strutting about with his white alsatian, unaware that he would soon be in for a surprise.

At dawn the owner of the apartment reappeared, and blundered into the kitchen where Wilder was resting. By now he had relaxed and was sitting comfortably on the floor with his back against the cooker, the remains of a meal scattered around him. He had found the few cans of food, along with two bottles of red wine, in their invariable hiding place, under the floorboards in the bedroom wardrobe. As he broke open the cans he played with a battery-powered tape-recorder which had been mixed up with the child's toys. He recorded his grunts and belches, playing them back to himself. Wilder was amused by the deft way in which he edited the tape, overlaying one set of belches with a second and third, a skill that now resided entirely in his scarred fingers with their cracked and blackened nails.

The bottles of claret had made him pleasantly drowsy. Smearing the red wine across his broad chest, he gazed up amiably at the startled woman who stumbled into the kitchen and tripped across his legs.

As she stared down at him, one hand nervously to her throat, Wilder remembered that she had once been called Charlotte Melville. The name had now detached itself from her, like an athlete's tie-on numeral blown away in a gust of wind. He knew that he had often been in this apartment, and this explained the vague familiarity of the child's toys and the furniture, although the chairs and sofa had been rearranged to conceal various hiding places.

"Wilder…?" As if uncertain about the name, Charlotte Melville pronounced it softly. She had been sheltering during the night with her son in the apartment of the statistician three floors above with whom she had become friendly. At the first light, when everything had settled down, she had come back intending to collect the last of her food reserves before abandoning the apartment for good. Swiftly composing herself, she looked down critically at the burly man with the exposed loins lying like a savage among her wine bottles, his chest painted with red stripes. She felt no sense of loss or outrage, but a fatalistic acceptance of the damage he had casually inflicted on her apartment, like the strong odour of his urine in the bathroom.

He appeared to be half asleep, and she stepped slowly towards the door. Wilder reached out with one hand and held her ankle. He smiled up at her blearily. Climbing to his feet, he circled around her, the tape-recorder raised in one hand as if about to hit her with it. Instead he switched it on and off, playing for her his selection of belches and grunts, obviously pleased with this demonstration of his unexpected expertise. He steered her slowly around the apartment as she backed from one room to the next, listening to his edited mutterings.

The first time he struck her, cuffing her to the bedroom floor, he tried to record her gasp, but the reel had jammed. He freed it carefully, bent down and slapped her again, only stopping when he had recorded her now deliberate cries to his satisfaction. He enjoyed terrorizing her, taping down her exaggerated but nonetheless frightened gasps. During their clumsy sexual act on the mattress in the child's bedroom he left the tape-recorder switched on beside them on the floor and played back the sounds of this brief rape, editing together the noise of her tearing clothes and panting anger.

Later, bored with the woman and these games with the tape-recorder, he hurled the machine into the corner. The sound of himself speaking, however coarsely, introduced a discordant element. He resented speaking to Charlotte or to anyone else, as if words introduced the wrong set of meanings into everything.

After she dressed they had breakfast together on the balcony, sitting at the table with an incongruous old-world formality. Charlotte ate the scraps of canned meat she found on the kitchen floor. Wilder finished the last of the claret, re-marking the red stripes across his chest. The rising sunlight warmed his exposed loins, and he felt like a contented husband sitting with his wife in a villa high on a mountainside. Naively, he wanted to explain to Charlotte his ascent of the apartment building, and shyly pointed to the roof. But she failed to get the point. She fastened her torn clothes around her strong body. Although her mouth and throat were bruised, she seemed unconcerned, watching Wilder with a passive expression.

From the balcony Wilder could see the roof of the high-rise, little more than a dozen floors above him. The intoxication of living at this height was as palpable as anything produced by the wine bottle in his hand. Already he could see the line of huge birds perched on the balustrades, no doubt waiting for him to arrive and take command.

Below, on the 20th floor, a man was cooking over a fire on his balcony, breaking up a coffee table and feeding the legs to the clutch of smouldering sticks on which a soup can was balanced.

A police car approached the perimeter entrance. A few residents were leaving for work at this early hour, neatly dressed in suits and raincoats, briefcases in hand. The abandoned cars in the access roads prevented the police from reaching the main entrance to the building, and the officers stepped out and spoke to the passing residents. Usually none of them would have replied to an outsider, but now they gathered in a group around the two policemen. Wilder wondered if they were going to give the game away, but although he could not hear them, he was certain that he knew what they were saying. Clearly they were pacifying the policemen, reassuring them that everything was in order, despite the garbage and broken bottles scattered around the building.

Deciding to test the defences of the apartment before he went to sleep, Wilder stepped into the corridor. He stood outside the doorway, as the stale air moved past him to the open balcony. He relished the rich smells of the high-rise. Like their garbage, the excrement of the residents higher up the building had a markedly different odour.

Returning to the balcony, he watched the police drive away in their car. Of the twenty or so residents who still left for work each morning, three had turned back, evidently unsettled by the task of convincing the police that all was well. Without looking up, they scurried back to the entrance lobby.

Wilder knew that they would never leave again. The separation of the high-rise from the world around it was now almost complete, and would probably coincide with his own arrival at the summit. Soothed by this image, he sat down on the floor and leaned against Charlotte Melville's shoulder, falling asleep as she stroked the wine-coloured stripes on his chest and shoulders.
