The Liar [calibre]

'And what does the note say?'

'It seems that we are being followed by two cars, one a French-registered blue Lemon BX, whatever that might be, the other a white Swiss Audi Four.'

'They must mean a Citroen BX and an Audi Quattro, I should think.'

'That would seem to make sense. Well, this is refreshing to know, is it not?'

'What, that we're being followed?'

'Yes.'

'But we stick out like a sore thumb in this bloody jalopy.'

'I hope so. The element of surprise is absolutely crucial.'

'What element of surprise?'

'Exactly!' beamed Trefusis as he edged onto the autoroute and pointed the Wolseley towards Germany. 'That is what is so surprising.'

The staccato rush of cars travelling in the opposite direction reminded Adrian of interminable childhood journeys to the coast. He would gaze at his father's cocked wrists on the steering wheel or count all the four-legged animals in the fields as they passed, one for a sheep or cow, two for a horse, yawning repeatedly in a giddy cloud of car-sickness. He had had a trick of covering his ears with his hands and removing them rhythmically in time to the whoosh of each car as it passed the window.

He tried it again now.

'Are we there yet, Daddy?'

'Why do people always say that on car journeys?' asked Trefusis.

'It reminds them of when they were young.'

'Humph.'

'Anyway,' said Adrian. 'We were talking about lies.'

'So we were. Light me a cigarette, there's a good fellow.'

Adrian lit two from Trefusis's cigarette case and passed one over.

Trefusis took in a deep lungful of Gold Leaf.

'We can be fairly certain,' he said, 'that animals do not lie. It has been both their salvation and their downfall. Lies, fictions and untrue suppositions can create new human truths which build technology, art, language, everything that is distinctly of Man. The word "stone" for instance is not a stone, it is an oral pattern of vocal, dental and labial sounds or a scriptive arrangement of ink on a white surface, but man pretends that it is actually the thing it refers to. Every time he wishes to tell another man about a stone he can use the word instead of the thing itself. The word bodies forth the object in the mind of the listener and both speaker and listener are able to imagine a stone without seeing one. All the qualities of stone can be metaphorically and metonymically expressed. "I was stoned, stony broke, stone blind, stone cold sober, stonily silent," oh, whatever occurs. More than that, a man can look at a stone and call it a weapon, a paperweight, a doorstep, a jewel, an idol. He can give it function, he can possess it.'

'Surely when a bird uses a twig for nesting material it is doing the same thing?'

'Birds collect for nests much as we expand our lungs a dozen or so times a minute in order to suck in air or, in our case, tobacco smoke. It is, or so I am reliably informed by those who know, an entirely instinctive mechanism. Animals do not have the lying capability of man.'

'Keats's negative capability?'

'To some extent, yes. Within our brains connections are made and stored all the time. This word signifies this thing, this fact actually occurred, this experience was in truth undergone; the whatness and whichness of everything is established. Thus I ask you, "What did you drink just now?" and you reply "lemon tea" because lemon tea and your recent drinking are connected. If you deliberately wish to lie you think "lemon tea" - you can't help that because the link is there - but you search for some other drinking material and say, for example, "apple juice". A link is now made between your recent drinking activities, lemon tea and apple juice. The strongest link, however, is between the drinking activity and lemon tea because it is the true one. The link between what you drank and apple juice exists, because you created it. But it only exists through the link with the lemon tea. Are you following me?'

'Like a panther,' lied Adrian.

'The details of a lie are harder to recall than the truth, because they are less strongly linked in the mind. The act of remembering is literally just that: the act of reassembling the members of something. If the members are illusory it is naturally more difficult to enact this mental reconstruction.'

'So your friend Szabo discovered what happens in the brains of people when they lie and has invented some kind of lie-detector, is that it?'

'No, no. He did much more than that. He discovered a lie-deftector!'

Adrian watched the smoke from his cigarette being sucked through the quarter-light of the car. He had an awful feeling, deep down inside him, that he was somehow more than a passenger on this journey, more than an observer.

'A lie-deflector?' he said.

'Let us suppose that all true things are connected in the brain by pathways called A-type pathways and all untrue things are connected by B-type pathways.'

'Okay.'

'Imagine a machine which inhibits the brain from making any B-type connections. When under the influence of such a machine, the subject is simply unable to lie.'

'And this is what your friend Szabo has come up with?'

'Such is his claim.'

Adrian thought for a moment.

'There are some lies,' he said, 'which you tell . . . which people tell ... so often that they believe them themselves. What about those?'

'However much you may consciously believe what you are saying, your brain knows the truth, and has made connections accordingly. You may imagine, for instance, that on holiday in Sardinia you witnessed a gang of twelve bandits robbing a bank with machine guns and hand grenades, you may repeat this story to the dismay of all your acquaintances at every dinner party to which those friends have made the rash mistake of inviting you, such that you believe it surely and wholly. Nonetheless, buried under the dead neural weight of all these convictions, your brain knows perfectly well that in fact there were only two bandits with nothing more than a water-pistol and a spud-gun between them. Your brain was there too, you see, and it has registered the truth.'

'I do see. I do.'

'Szabo claims the machine is in fact as much a memory-retrieval device as a lie-inhibitor. It can just as easily make the subject disinter the German for "chive" as disgorge the details of his true whereabouts on the night in question.'

'Wow.'

'W, as you rightly remark, ow. Or, as they say in Poland, "Vov".'

'And where do you fit into all this?'

'Nowhere in the development of the machine. Bela and I have corresponded over the decades, and a little over a year ago he began to include in his letters to me references to his development of Mendax, as he has fancifully dubbed this fruit of his intellectual loins. Last July Istvan Moltaj, a violinist friend of his, left Hungary to take part in the Salzburg Festival. Bela entrusted him with a sheaf of papers relating to Mendax. The idea was that Moltaj should give the papers to me. We had an appointment to meet at Mozart's Geburtshaus in the Getreide-gasse. It is apparent that someone had either been following Moltaj or had intercepted Bela's letter to me arranging the rendezvous. He was there most unpleasantly killed, not ten yards away from us, as we both have cause to remember.'

'And he never got to give you the papers?'

'Moltaj had taken the sensible precaution of leaving a package for my collection at the reception desk of the Goldener Hirsch Hotel. The package contained a sheaf of musical manuscript paper. A duet for piano and violin. The music was cacophonous in the extreme but the notes corresponded to letters which spelt out a text in classical Volapuk.'

'So you got it?'

'You may remember that on our return to England last year we were robbed?'

'They took your briefcase!'
