And with that question still ringing in Smiley's ears they had arrived at last at the body, floating like an embryo under its plastic film.

But Smiley, on this morning after, stopped short of the dip. Instead, by placing his sodden shoes as best he could upon each spot exactly, he set about trying to imitate the movements the old man might have made. And since Smiley did all this in slow motion, and with every appearance of concentration, under the eye of two trousered ladies walking their Alsatians, he was taken for an adherent of the new fad in Chinese martial exercises, and accounted mad accordingly.

First he put his feet side by side and pointed them down the hill. Then he put his left foot forward, and moved his right foot round until the toe pointed directly towards a spinney of young saplings. As he did so, his right shoulder followed naturally, and his instinct told him that this would be the likely moment for Vladimir to transfer the stick to his left hand. But why ? As the Superintendent had also asked, why transfer the stick at all? Why,in this most extreme moment of his life, why solemnly move a walking stick from the right hand to the left? Certainly not to defend himself - since, as Smiley remembered, he was right-handed. To defend himself, he would only have seized the stick more firmly. Or clasped it with both his hands, like a club.

Was it in order to leave his right hand free? But free for what?

Aware this time of being observed, Smiley peered sharply behind him and saw two small boys in blazers who had paused to watch this round little man in spectacles performing strange antics with his feet. He glowered at them in his most schoolmasterly manner, and they moved hastily on.

To leave his right hand free for what? Smiley repeated to himself. And why start running again a moment later?

Vladimir turned to the right, thought Smiley, once again matching his action to the thought. Vladimir turned to the right. He faced the spinney, he put his stick in his left hand. For a moment, according to the Superintendent, he stood still. Then he ran on.

Moscow Rules , Smiley thought, staring at his own right hand. Slowly he lowered it into his raincoat pocket. Which was empty, as Vladimir's right-hand coat pocket was also empty.

Had he meant to write a message perhaps? Smiley was teasing himself with the theory he was determined to hold at bay. To write a message with the chalk for instance? Had he recognized his pursuer, and wished to chalk a name somewhere, or a sign? But what on ? Not on these wet tree trunks for sure. Not on the clay, the dead leaves, the gravel! Looking round him, Smiley became aware of a peculiar feature of his location. Here, almost between two trees, at the very edge of the avenue, at the point where the fog was approaching its thickest, he was as good as out of sight. The avenue descended, yes, and lifted ahead of him. But it also curved, and from where he stood the upward line of sight in both directions was masked by tree trunks and a dense thicket of saplings. Along the whole path of Vladimir's last frantic journey - a path he knew well, remember, had used for similar meetings - this was the point, Smiley realized with increasing satisfaction, where the fleeing man was out of sight from both ahead of him and behind him.

And had stopped.

Had freed his right hand.

Had put it - let us say - in his pocket.

For his heart tablets? No. Like the yellow chalk and the matches, they were in his left pocket, not his right.

For something - let us say - that was no longer in the pocket when he was found dead.

For what then?

Tell him I have two proofs and can bring them with me ... Then perhaps he will see me ... This is Gregory asking for Max . I have something for him, please ...

Proofs. Proofs too precious to post. He was bringing something. Two somethings. Not just in his head - in his pocket. And was playing Moscow Rules. Rules that had been drummed into the General from the very day of his recruitment as a defector in place. By Smiley himself, no less, as well as his case officer on the spot. Rules that had been invented for his survival; and the survival of his network. Smiley felt the excitement seize his stomach like a nausea. Moscow Rules decree that, if you physically carry a message, you must also carry the means to discard it! That, however it is disguised or concealed - microdot, secret writing, undeveloped film, anyone of the hundred risky, finicky ways - still as an object it must be the first and lightest thing that comes to hand, the least conspicuous when jettisoned !

Such as a medicine bottle full of tablets, he thought, calming a little. Such as a box of matches.

One box Swan Vesta matches partly used, overcoat left , he remembered. A smoker's match, note well.

And in the safe flat, he thought relentlessly - tantalizing himself, staving off the final insight - there on the table waiting for him, one packet of cigarettes, Vladimir's favourite brand. And in Westbourne Terrace on the food safe, nine packets of Gauloises Caporal. Out of ten.

But no cigarettes in his pockets. None, as the good Superintendent would have said, on his person. Or not when they found him, that is to say.

So the premise, George? Smiley asked himself, mimicking Lacon - brandishing Lacon's prefectorial finger accusingly in his own intact face - the premise? The premise is thus far, Oliver, that a smoker, a habitual smoker, in a state of high nervousness, sets off on a crucial clandestine meeting equipped with matches but not even so much as an empty packet of cigarettes, though he possesses quite demonstrably a whole stock of them. So that either the assassins found it, and removed it - the proof, or proofs, which Vladimir was speaking of, or - or what? Or Vladimir changed his stick from his right hand to his left in time. And put his right hand in his pocket in time. And took it out again, also in time, at the very spot where he could not be seen. And got rid of it, or them, according to Moscow Rules.

Having satisfied his own insistence upon a logical succession, George Smiley stepped cautiously into the long grass that led to the spinney, soaking his trousers from the knees down. For half an hour or more he searched, groping in the grass and among the foliage, retreading his tracks, cursing his own blundering, giving up, beginning again, answering the fatuous enquiries of passers-by which ranged from the obscene to the excessively attentive. There were even two Buddhist monks from a local seminary, complete with saffron robes and lace-up boots and knitted woollen caps, who offered their assistance. Smiley courteously declined it. He found two broken kites, a quantity of Coca-Cola tins. He found scraps of the female body, some in colour, some in black and white, ripped from magazines. He found an old running shoe, black, and shreds of an old burnt blanket. He found four beer bottles, empty, and four empty cigarette packets so sodden and old that after one glance he discounted them. And in a branch, slipped into the fork just where it joined its parent trunk, the fifth packet, or better perhaps the tenth of that was not even empty; a relatively dry packet of Gauloises Caporal, Filtre and Duty Free, high up. Smiley reached for it as if it were forbidden fruit but like forbidden fruit it stayed outside his grasp. He jumped for it and felt his back rip : a distinct and unnerving parting of tissue that smarted and dug at him for days afterwards. He said 'damn' out loud and rubbed the spot, much as Ostrakova might have done. Two typists, on their way to work, consoled him with their giggles. He found a stick, poked the packet free, opened it. Four cigarettes remained.

And behind those four cigarettes, half concealed, and protected by its own skin of cellophane, something he recognized but dared not even disturb with his wet and trembling fingers. Something he dared not even contemplate until he was free of this appalling place, where giggling typists and Buddhist monks innocently trampled the spot where Vladimir had died.

They have one, I have the other, he thought. I have shared the old man's legacy with his murderers.

Braving the traffic, he followed the narrow pavement down the hill till he came to South End Green, where he hoped for a café that would give him tea. Finding none open so early, he sat on a bench across from a cinema instead, contemplating an old marble fountain and a pair of red telephone boxes, one filthier than the other. A warm drizzle was falling; a few shopkeepers had started lowering their awnings; a delicatessen store was taking delivery of bread. He sat with hunched shoulders, and the damp points of his mackintosh collar stabbed his unshaven cheeks whenever he turned his head. 'For God's sake mourn!' Ann had flung at Smiley once, infuriated by his apparent composure after yet another friend had died. 'If you won't grieve for the dead, how can you love the living?' Sitting on his bench, pondering his next step, Smiley now transmitted to her the answer he had failed to find at the time. 'You are wrong,' he told her distractedly. 'I mourn the dead sincerely, and Vladimir, at this moment, deeply. It's loving the living which is sometimes a bit of a problem.'

He tried the telephone boxes and the second worked. By a miracle, even the S-Z directory was intact and, more amazing still, the Straight and Steady Minicab Service of Islington North had paid for the privilege of heavy type. He dialled the number and while it rang out he had a panic that he had forgotten the name of the signatory on the receipt in Vladimir's pocket. He rang off, recovering his two pence. Lane? Lang? He dialled again.

A female voice answered him in a bored singsong : 'Straight-and-Stead-ee! Name-when-and-where-to please?'

'I'd like to speak to Mr J. Lamb, please, one of your drivers,' Smiley said politely.

'Sorr-ee, no personal calls on this lin-er ,' she sang and rang off.

He dialled a third time. It wasn't personal at all, he said huffily, now surer of his ground. He wanted Mr Lamb to drive for him, and nobody but Mr Lamb would do. 'Tell him it's a long journey. Stratford-on-Avon' - choosing a town at random - 'tell him I want to go to Stratford.' Sampson , he replied, when she insisted on a name. Sampson with a 'p'.

He returned to his bench to wait again.

To ring Lacon? For what purpose? Rush home, open the cigarette packet, find out its precious contents? It was the first thing Vladimir threw away, he thoughe in the spy trade we abandon first what we love the most. I got the better end of the bargain after all. An elderly couple had settled opposite him. The man wore a stiff Homburg hat and was playing war tunes on a tin whistle. He wife grinned inanely at the passers-by. To avoid her gaze, Smiley remembered the brown envelope from Paris, and tore it open, expecting what? A bill probably, some hangover from the old boy's life there. Or one of those cyclostyled battle-cries that émigrés send each other like Christmas cards. But this was neither a bill nor a circular but a personal letter : an appeal, but of a very special sort. Unsigned, no address for the sender. In French, handwritten very fast. Smiley read it once and he was reading it a second time when an overpainted Ford Cortina, driven by a boy in a polo neck pullover, skidded to a giddy halt outside the cinema. Returning the letter to his pocket, he crossed the road to the car.
