Recovering a little, Larsen sat up. He smoothed down his cream gabardine suit and brushed the dust off his brown-and-white shoes. ‘Thanks for warning me. All you’ve got to do now is tell me who he is.’
Bayliss sat down in one of the chairs. ‘What do you mean, who he is? He’s you, of course.’
‘I know that, but why, where does he come from? God, I must be going insane.’
Bayliss snapped his fingers. ‘No you’re not. Pull yourself together. This is a purely functional disorder, like double vision or amnesia; nothing more serious. If it was, I’d have pulled you out of here long ago. Perhaps I should have done that anyway, but I think we can find a safe way out of the maze you’re in.’
He took a notebook out of his breast pocket. ‘Let’s have a look at what we’ve got. Now, two features stand out. First, the phantom is yourself. There’s no doubt about that; he’s an exact replica of you. More important, though, he is you as you are now, your exact contemporary in time, unidealized and unmutilated. He isn’t the shining hero of the super-ego, or the haggard grey-beard of the death wish. He is simply a photographic double. Displace one eyeball with your finger and you’ll see a double of me. Your double is no more unusual, with the exception that the displacement is not in space but in time. You see, the second thing I noticed about your garbled description of this phantom was that, not only was he a photographic double, but he was doing exactly what you yourself had been doing a few minutes previously. The man in the garage was standing by the workbench, just where you stood when you were wondering whether to take the can of petrol. Again, the man reading in the armchair was merely repeating exactly what you had been doing with the same book five minutes earlier. He even stared out of the window as you say you did before going out for a stroll.’
Larsen nodded, sipping his whisky. ‘You’re suggesting that the hallucination was a mental flashback?’
‘Precisely. The stream of retinal images reaching the optic lobe is nothing more than a film strip. Every image is stored away, thousands of reels, a hundred thousand hours of running time. Usually flashbacks are deliberate, when we consciously select a few blurry stills from the film library, a childhood scene, the image of our neighbourhood streets we carry around with us all day near the surface of consciousness. But upset the projector slightly — overstrain could do it — jolt it back a few hundred frames, and you’ll superimpose a completely irrelevant strip of already exposed film, in your case a glimpse of yourself sitting on the sofa. It’s the apparent irrelevancy that is so frightening.’
Larsen gestured with his glass. ‘Wait a minute, though. When I was sitting on the sofa reading Kretschmer I didn’t actually see myself, any more than I can see myself now. So where did the superimposed images come from?’
Bayliss put away his notebook. ‘Don’t take the analogy of the film strip too literally. You may not see yourself sitting on that sofa, but your awareness of being there is just as powerful as any visual corroboration. It’s the stream of tactile, positional and psychic images that form the real data store. Very little extrapolation is needed to transpose the observer’s eye a few yards to the other side of a room. Purely visual memories are never completely accurate anyway.’
‘How do you explain why the man I saw in the garage was transparent?’
‘Quite simply. The process was only just beginning, the intensity of the image was weak. The one you saw this afternoon was much stronger. I cut you off barbiturates deliberately, knowing full well that those stimulants you were taking on the sly would set off something if they were allowed to operate unopposed.’
He went over to Larsen, took his glass and refilled it from the decanter. ‘But let’s think of the future. The most interesting aspect of all this is the light it throws on one of the oldest archetypes of the human psyche — the ghost — and the whole supernatural army of phantoms, witches, demons and so on. Are they all, in fact, nothing more than psychoretinal flashbacks, transposed images of the observer himself, jolted on to the retinal screen by fear, bereavement, religious obsession? The most notable thing about the majority of ghosts is how prosaically equipped they are, compared with the elaborate literary productions of the great mystics and dreamers. The nebulous white sheet is probably the observer’s own nightgown. It’s an interesting field for speculation. For example, take the most famous ghost in literature and reflect how much more sense Hamlet makes if you realize that the ghost of his murdered father is really Hamlet himself.’
‘All right, all right,’ Larsen cut in irritably. ‘But how does this help me?’
Bayliss broke off his reflective up-and-down patrol of the floor and fixed an eye on Larsen. ‘I’m coming to that. There are two methods of dealing with this disfunction of yours. The classical technique is to pump you full of tranquillizers and confine you to a bed for a year or so. Gradually your mind would knit together. Long job, boring for you and everybody else. The alternative method is, frankly, experimental, but I think it might work. I mentioned the phenomenon of the ghost because it’s an interesting fact that although there have been tens of thousands of recorded cases of people being pursued by ghosts, and a few of the ghosts themselves being pursued, there have been no cases of ghost and observer actually meeting of their own volition. Tell me, what would have happened if, when you saw your double this afternoon, you had gone straight into the lounge and spoken to him?’
Larsen shuddered. ‘Obviously nothing, if your theory holds. I wouldn’t like to test it.’
‘That’s just what you’re going to do. Don’t panic. The next time you see a double sitting in a chair reading Kretschmer, go up and speak to him. If he doesn’t reply sit down in the chair yourself. That’s all you have to do.’
Larsen jumped up, gesticulating. ‘For heaven’s sake, Bayliss, are you crazy? Do you know what it’s like to suddenly see yourself? All you want to do is run.’
‘I realize that, but it’s the worst thing you can do. Why whenever anyone grapples with a ghost does it always vanish instantly? Because forcibly occupying the same physical co-ordinates as the double jolts the psychic projector on to a single channel again. The two separate streams of retinal images coincide and fuse. You’ve got to try, Larsen. It may be quite an effort, but you’ll cure yourself once and for all.’
Larsen shook his head stubbornly. ‘The idea’s insane.’ To himself he added: I’d rather shoot the thing. Then he remembered the .38 in his suitcase, and the presence of the weapon gave him a stronger sense of security than all Bayliss’s drugs and advice. The revolver was a simple symbol of aggression, and even if the phantom was only an intruder in his own mind, it gave that portion which still remained intact greater confidence, enough possibly to dissipate the double’s power.
Eyes half closed with fatigue, he listened to Bayliss. Half an hour later he went back to his chalet, found the revolver and hid it under a magazine in the letterbox outside the front door. It was too conspicuous to carry and anyway might fire accidentally and injure him. Outside the front door it would be safely hidden and yet easily accessible, ready to mete out a little old-fashioned punishment to any double dealer trying to get into the game.
Two days later, with unexpected vengeance, the opportunity came.
Bayliss had driven into town to buy a new stylus for the stereogram, leaving Larsen to prepare lunch for them while he was away. Larsen pretended to resent the chore, but secretly he was glad of something to do. He was tired of hanging around the chalets while Bayliss watched him as if he were an experimental animal, eagerly waiting for the next crisis. With luck this might never come, if only to spite Bayliss, who had been having everything too much his own way.
