hope you weren’t too bored,’ Sheringham said as he handled the decanter. ‘Microsonics is a fascinating hobby, but I’m afraid I may have let it become an obsession.’
Maxted grunted non-committally. ‘Some of the records are interesting,’ he admitted. ‘They have a sort of crazy novelty value, like blown-up photographs of moths’ faces and razor blades. Despite what you claim, though, I can’t believe microsonics will ever become a scientific tool. It’s just an elaborate laboratory toy.’
Sheringham shook his head. ‘You’re completely wrong, of course. Remember the cell division series I played first of all? Amplified 100,000 times animal cell division sounds like a lot of girders and steel sheets being ripped apart – how did you put it? – a car smash in slow motion. On the other hand, plant cell division is an electronic poem, all soft chords and bubbling tones. Now there you have a perfect illustration of how microsonics can reveal the distinction between the animal and plant kingdoms.’
‘Seems a damned roundabout way of doing it,’ Maxted commented, helping himself to soda. ‘You might as well calculate the speed of your car from the apparent motion of the stars. Possible, but it’s easier to look at the speedometer.’
Sheringham nodded, watching Maxted closely across the table. His interest in the conversation appeared to have exhausted itself, and the two men sat silently with their glasses. Strangely, the hostility between them, of so many years’ standing, now became less veiled, the contrast of personality, manner and physique more pronounced. Maxted, a tall fleshy man with a coarse handsome face, lounged back almost horizontally in his chair, thinking about Susan Sheringham. She was at the Turnbulls’ party, and but for the fact that it was no longer discreet of him to be seen at the Turnbulls’ – for the all-too-familiar reason – he would have passed the evening with her, rather than with her grotesque little husband.
He surveyed Sheringham with as much detachment as he could muster, wondering whether this prim unattractive man, with his pedantry and in-bred academic humour, had any redeeming qualities whatever. None, certainly, at a casual glance, though it required some courage and pride to have invited him round that evening. His motives, however, would be typically eccentric.
The pretext, Maxted reflected, had been slight enough – Sheringham, professor of biochemistry at the university, maintained a lavish home laboratory; Maxted, a run-down athlete with a bad degree, acted as torpedo-man for a company manufacturing electron microscopes; a visit, Sheringham had suggested over the phone, might be to the profit of both.
Of course, nothing of this had in fact been mentioned. But nor, as yet, had he referred to Susan, the real subject of the evening’s charade. Maxted speculated upon the possible routes Sheringham might take towards the inevitable confrontation scene; not for him the nervous circular pacing, the well-thumbed photostat, or the tug at the shoulder. There was a vicious adolescent streak running through Sheringham –
Maxted broke out of his reverie abruptly. The air in the patio had become suddenly cooler, almost as if a powerful refrigerating unit had been switched on. A rash of goose-flesh raced up his thighs and down the back of his neck, and he reached forward and finished what was left of his whisky.
‘Cold out here,’ he commented.
Sheringham glanced at his watch. ‘Is it?’ he said. There was a hint of indecision in his voice; for a moment he seemed to be waiting for a signal. Then he pulled himself together and, with an odd half-smile, said: ‘Time for the last record.’
‘What do you mean?’ Maxted asked.
‘Don’t move,’ Sheringham said. He stood up. ‘I’ll put it on.’ He pointed to a loudspeaker screwed to the wall above Maxted’s head, grinned and ducked out.
Shivering uncomfortably, Maxted peered up into the silent evening sky, hoping that the vertical current of cold air that had sliced down into the patio would soon dissipate itself.
A low noise crackled from the speaker, multiplied by a circle of other speakers which he noticed for the first time had been slung among the trellis-work around the patio.
Shaking his head sadly at Sheringham’s antics, he decided to help himself to more whisky. As he stretched across the table he swayed and rolled back uncontrollably into his chair. His stomach seemed to be full of mercury, ice-cold and enormously heavy. He pushed himself forward again, trying to reach the glass, and knocked it across the table. His brain began to fade, and he leaned his elbows helplessly on the glass edge of the table and felt his head fall onto his wrists.
When he looked up again Sheringham was standing in front of him, smiling sympathetically.
‘Not too good, eh?’ he said.
Breathing with difficulty, Maxted managed to lean back. He tried to speak to Sheringham, but he could no longer remember any words. His heart switchbacked, and he grimaced at the pain.
‘Don’t worry,’ Sheringham assured him. ‘The fibrillation is only a side effect. Disconcerting, perhaps, but it will soon pass.’
He strolled leisurely around the patio, scrutinizing Maxted from several angles. Evidently satisfied, he sat down on the table. He picked up the siphon and swirled the contents about. ‘Chromium cyanate. Inhibits the coenzyme system controlling the body’s fluid balances, floods hydroxyl ions into the bloodstream. In brief, you drown. Really drown, that is, not merely suffocate as you would if you were immersed in an external bath. However, I mustn’t distract you.’
He inclined his head at the speakers. Being fed into the patio was a curiously muffled spongy noise, like elastic waves lapping in a latex sea. The rhythms were huge and ungainly, overlaid by the deep leaden wheezing of a gigantic bellows. Barely audible at first, the sounds rose until they filled the patio and shut out the few traffic noises along the highway.
‘Fantastic, isn’t it?’ Sheringham said. Twirling the siphon by its neck he stepped over Maxted’s legs and adjusted the tone control under one of the speaker boxes. He looked blithe and spruce, almost ten years younger. ‘These are 30-second repeats, 400 microsens, amplification one thousand. I admit I’ve edited the track a little, but it’s still remarkable how repulsive a beautiful sound can become. You’ll never guess what this was.’
Maxted stirred sluggishly. The lake of mercury in his stomach was as cold and bottomless as an oceanic trench, and his arms and legs had become enormous, like the bloated appendages of a drowned giant. He could just see Sheringham bobbing about in front of him, and hear the slow beating of the sea in the distance. Nearer now, it pounded with a dull insistent rhythm, the great waves ballooning and bursting like bubbles in a lava sea.
‘I’ll tell you, Maxted, it took me a year to get that recording,’ Sheringham was saying. He straddled Maxted, gesturing with the siphon. ‘A year. Do you know how ugly a year can be?’ For a moment he paused, then tore himself from the memory. ‘Last Saturday, just after midnight, you and Susan were lying back in this same chair. You know, Maxted, there are audio-probes everywhere here. Slim as pencils, with a six-inch focus. I had four in that headrest alone.’ He added, as a footnote: ‘The wind is your own breathing, fairly heavy at the time, if I remember; your interlocked pulses produced the thunder effect.’
Maxted drifted in a wash of sound.
Some while later Sheringham’s face filled his eyes, beard wagging, mouth working wildly.
‘Maxted! You’ve only two more guesses, so for God’s sake concentrate,’ he shouted irritably, his voice almost lost among the thunder rolling from the sea. ‘Come on, man, what is it? Maxted!’ he bellowed. He leapt for the nearest loudspeaker and drove up the volume. The sound boomed out of the patio, reverberating into the night.
Maxted had almost gone now, his fading identity a small featureless island nearly eroded by the waves beating across it.
Sheringham knelt down and shouted into his ear.
‘Maxted, can you hear the sea? Do you know where you’re drowning?’
A succession of gigantic
