To Ray Poynton and all his team.
Fons et Origo,
He the one and I the other.
You may reasonably expect a man to walk a tightrope safely for ten minutes; it would be unreasonable to do so without accident for two hundred years.
Bertrand Russell
Giles Denison lay asleep. He lay on his back with his right arm held crooked across his forehead with the hand lightly clenched into a fist, giving him a curiously defensive appearance as of one who wards off a blow. His breathing was even and shallow but it deepened a little as he came into consciousness in that everyday miracle of the reintegration of the psyche after the little death of sleep. There was a movement of eyes behind closed lids and he sighed, bringing his arm down and turning over on to his side to snuggle deeper into the bedclothes. After a few moments the eyelids flickered and drew back and he stared uncomprehendingly at the blank wall next to the bed. He sighed again, filling his lungs with air, and then leisurely drew forth his arm and looked at his wristwatch. It was exactly twelve o’clock. He frowned and shook the watch, then held it to his ear. A steady tick told him it was working and another glance at the dial showed the sweep second hand jerking smoothly on its circular course. Suddenly – convulsively – he sat up in bed and stared at the watch. It was not the time – midday or midnight – that now perturbed him, but the realization that this was not his watch. He normally wore a fifteen-year-old Omega, a present from his father on his twenty-first birthday, but this was a sleek Patek Philippe, gleaming gold, with a plain leather strap instead of the flexible metal band he was accustomed to. A furrow creased his forehead as he stroked the dial of the watch with his forefinger and then, as he raised his eyes to look about the room, he received another shock. He had never been in the room before. He became aware that his heart thumped in his chest and he raised his hand to feel the coolness of silk against his fingers. He looked down and saw the pyjamas. Habitually he slept peeled to the skin; pyjamas constricted him and he had once said that he never saw the sense in getting dressed to go to bed. Denison was still half asleep and his first impulse was to he down and wait for the dream to be over so that he could wake up again in his own bed, but a pressing necessity of nature was suddenly upon him and he had to go to the bathroom. He shook his head irritably and threw aside the bedclothes – not the sheets and blankets to which he was accustomed but one of those new-fangled quilt objects which fashion had recently imported from the Continent. He swung his legs out of the bed and sat up, looking down at the pyjamas again. I’m in hospital, he thought suddenly; I must have had an accident. Recollection told him otherwise. He had gone to bed in his own flat in Hampstead in the normal way, after perhaps a couple of drinks too many the previous evening. Those extra couple of drinks had become a habit after Beth died. His fingers caressed the softness of the silk. Not a hospital, he decided; these were not National Health issue – not with an embroidered monogram on the pocket. He twisted his head to see the letters but the embroidery was complex and the monogram upside down and he could not make it out. He stood up and looked about the room and knew immediately he was in a hotel. There were expensive-looking suitcases and in no other place but a hotel room could you find special racks on which to put them. He walked three paces and stroked the fine-grained leather which had hardly a scuff mark. The initials on the side of the suitcase were plain and unmonogrammed – H.F.M. His head throbbed with the beginning of a headache – the legacy of those extra couple of drinks – and his mouth was parched. He glanced around the room and noted the unrumpled companion bed, the jacket hanging tidily on the back of a chair and the scatter of personal possessions on the dressing-table. He was about to cross to the dressing-table when the pressure in his bladder became intolerable and he knew he had to find a bathroom. He turned and stumbled into the small hall off the bedroom. One side was panelled in wood and he swung a door open to find a wardrobe full of hung clothes. He turned again and found a door on the other side which opened into darkness. He fumbled for a switch, found it, and light sprang up in a white-tiled bathroom. While he was relieving himself his mind worried about the electric switch, wondering what was strange about it, and then he realized that it was reversed – an upward movement to turn on the light instead of the more normal down pressure. He flushed the toilet and turned to the hand basin seeking water. Two glasses stood on a shelf, wrapped in translucent paper. He took one down, ripped off the paper and, filling it with water from the green-topped tap, he drank thirstily. Up to this moment he had been awake for, perhaps, three minutes. He put down the glass and rubbed his left eye which was sore. Then he looked into the mirror above the basin and, for the first time in his life, experienced sheer terror. When Alice went through the Looking Glass the flowers talked to her and she evinced nothing but a mild surprise; but a psychologist once observed, ‘If a flower spoke to a man, that man would know terror.’ So it was with Giles Denison. After seeing the impossible in the bathroom mirror he turned and vomited into the toilet bowl, but his laboured retchings brought up nothing but a thin mucus. Panting with his efforts, he looked into the mirror again – and reason left him. When he became self-aware he found himself prone on the bed, his hands shaped into claws which dug into the pillow. A single sentence was drumming through his mind with mechanical persistence. ‘I am Giles Denison! I am Giles Denison! I AM Giles Denison! I am GILES DENISON!’ Presently his heavy breathing quieted and he was able to think beyond that reiterated statement of identity. With his head sideways on the pillow he spoke aloud, gathering reassurance from the familiar sound of his own voice. In a slurred tone which gradually became firmer he said, ‘I am Giles Denison. I am thirty-six years old. I went to bed last night in my own home. I was a bit cut, that’s true, but not so drunk as to be incapable. I remember going to bed – it was just after midnight.’ He frowned, then said, ‘I’ve been hammering the bottle a bit lately, but I’m not an alcoholic – so this isn’t the DTs. Then what is it?’ His left hand moved up to stroke his cheek. ‘What the hell is this?’ He arose slowly and sat on the edge of the bed, screwing up his nerve to go back into the bathroom as he knew he must. When he stood up he found his whole body trembling and he waited a while until the fit had passed. Then he walked with slow paces into the bathroom to face again the stranger in the mirror. The face that looked back at him was older – he judged the man to be in his mid-forties. Giles Denison had worn a moustache and a neatly clipped beard – the stranger was clean shaven. Giles Denison had a full head of hair – the stranger’s hair receded at the temples. Denison had no distinguishing marks as called for in passport descriptions – the stranger had an old scar on the left side of his face which passed from the temple across the cheekbone to the corner of the mouth; the left eyelid drooped, whether as a result
