'Yes,' he said. 'We don't know why. Robbie thinks the ultrashort-wave may have therapeutic value in itself. Mac doesn't agree. He believes that when he puts out the call it connects Niki with what he calls Force Six, which in her case is doubled because of the dead twin.'
Ken spoke as if this fantastic theory was perfectly natural.
'Do you mean,' I asked, 'that when the call goes through the dead twin somehow takes over?'
Ken laughed. He walked so fast it was hard to keep up with him.
'Ghoulies and ghosties?' he queried. 'Good Lord, no! There's nothing left of poor Penny but electric energy, still attached to her living twin. That's why Niki makes such a useful guinea-pig.'
He glanced across at me, smiling.
'When I go,' he said, 'Mac plans to tap my energy too. Don't ask me how. I just don't know. But he's welcome to have a crack at it.'
We went on walking. The sour smell of stagnant water rose from the marsh on either side of us. The wind strengthened, flattening the reeds. The tower of Saxmere loomed ahead, hard and black against a russet sky.
I had the voice production unit functioning to my satisfaction within the next few days. We fed it with tape, programmed in advance as we had done at A.E.L., but the vocabulary was more extensive, consisting of a call signal 'This is Charon speaking… this is Charon speaking…' followed by a series of numbers, spoken with great clarity. Then came questions, most of them quite simple, such as, 'Are you O.K.?' 'Does anything bother you?', proceeding to statements of fact like, 'You are not with us. You are at Thirlwall. It is two years back. Tell us what you see,' and so on. My job was to control the precision of the voice, the programme was Mac's responsibility, and, if the questions and statements appeared inane to me, doubtless they made sound sense to him.
On Friday he told me that he considered Charon was ready for use the next day, and Robbie and Ken were warned for eleven a.m. Mac himself would be at the controls, and I was to watch. In the light of what I had already witnessed, I should have been fully prepared for what happened. Oddly enough, I was not. I took up my station in the adjoining lab, while Ken stretched himself out on the operating-table.
It's all right,' he said to me with a wink. 'Robbie isn't going to carve me up.'
There was a microphone in position above his head, with a lead going through to Charon 1. A yellow light for 'Stand-by' flashed on the wall. It changed to red. I saw Ken close his eyes. Then a voice came front Charon. 'This is Charon speaking…
This is Charon speaking.' The series of numbers followed, and, after a pause, the question, 'Are you O.K.?'
When Ken replied, 'Yes, I'm O.K.' I noticed that his voice lacked its usual buoyancy; it was flatter, pitched in a lower key. I glanced at Robbie; he handed me a slip of paper on which were written the words, 'He's under hypnosis'.
The penny dropped, and I realised for the first time the full importance of the sound unit and the reason for perfecting it. Ken had been conditioned to hypnosis by the electronic voice. The questions on the programme were not haphazard, they were taped for him. The implications of this were even more shocking to me than when I had seen the dog and the child obey the call signal from a distance. When Ken, jokingly, had spoken of 'going to work', this was what he had meant.
'Does anything bother you?' asked the voice.
There was a long pause before the answer, and when it came the tone was impatient, almost fretful.
'It's the hanging about. I want it to happen quickly. If it could be over and done with, then I wouldn't give a damn.'
I might have been standing by a confessional, and I understood now why my predecessor had turned in his job. I saw Robbie's eyes upon me; the demonstration had been staged not only to show Ken's co-operation under hypnosis, proved no doubt dozens of times already, but to test my nerve. The ordeal continued. Much of what Ken said made painful hearing. I don't want to repeat it here. It revealed the unconscious strain under which he lived, never outwardly apparent either to us or to himself.
The programme Mac used was not one I had heard before, and it ended with the words, 'You'll be all right, Ken. You aren't alone. We're with you every step of the way. O.K.?'
A faint smile passed over the quiet face.
'O.K.'
Then the numbers were repeated, in swifter sequence, ending with the words 'Wake up, Ken!'
The boy stretched himself, opened his eyes and sat up. He looked first at Robbie, then at me, and grinned.
'Did old Charon do his stuff?' he asked.
'One hundred per cent,' I answered, my voice falsely hearty. Ken slid off the operating table, his work for the morning done. I went through to Mac, standing by the controls.
'Thanks, Steve,' he said. 'You can appreciate the necessity for Charon 1 now. An electronic voice, plus a planned programme, eliminates emotion on our part, which will be essential when the time comes. That's the reason Ken has been conditioned to the machine. He responds very well. But better, of course, if the child is with him.'
'The child'?' I repeated.
'Yes,' he answered. 'Niki is an essential part of the experiment. She is conditioned to the voice too, and the pair of them chat away together as gay as crickets. They know nothing about it afterwards, naturally.' He paused, watching me closely as Robbie had done. 'Ken will almost certainly go into coma at the end. The child will be our only link with him then. Now, I suggest you borrow a car, drive into Thirlwall and buy yourself a drink.'
He turned away, craggy, imperturbable, suggesting a benevolent bird of prey.
I didn't go into Thirlwall. I walked out across the sand-dunes to the sea. There was nothing calm about it today. Turbulent and grey, it sank into troughs before breaking on the shingle with a roar. Miles away along the beach a group of U.S. Air Corps cadets were practising bugle calls. The shrill notes, the discordant sounds, drove towards me down the wind. For no reason at all the half-forgotten lines of a Negro spiritual kept repeating themselves over and over in my mind.
'He has the whole world in his hands,
He has the whole world in his hands…'
The demonstration was repeated, with varying programmes, every three days during the weeks that followed. Mac and I took it in turn at the controls. I soon grew accustomed to this, and the bizarre sessions became a matter of routine.
It was, as Mac had said, less painful when the child was present. Her father would bring her to the lab and leave her with us, Ken already in position and under control. The child would sit in a chair beside him, also with a microphone above her head to record her speech. She was told that Ken was asleep. Then, in her turn, she would receive the signal from Charon, and a different series of numbers from Ken's, after which she would be under control. The programme was different when the two were working together. Charon would take Ken back in time, to a period when he was the same age as Niki, saying, 'You are seven years old. Niki has come to play with you. She is your friend,' and a similar message would be given to the child, 'Ken has come to play with you. He is a boy of your age.'
The two would then chat together, without interruption from Charon, with the quite fantastic result-this had been built up during the past months, I gathered-that the pair were now close friends 'in time', hiding nothing from each other, playing imaginary games, exchanging ideas. Niki, backward and morose when conscious, was lively and gay under control. The taped conversations were checked after each session, to record the increasingly closer rapport between the two, and to act as guide for further programmes. Ken, when conscious, looked upon Niki as Janus's backward child, a sad little object of no interest. He was totally ignorant of what happened when under control. I was not so sure about Niki. Intuition seemed to draw her to him She would hang about him, if given the chance.
