John le Carr� - Tinker Tailor Soldier Spy

Backtracking again, he established that the converse was also true: that the reports he had discarded on the grounds that they had no close attachment to recent events were those which most generally went into distribution while Polyakov was in Moscow or on leave.

And then he had it.

No explosive revelation, no flash of light, no cry of 'Eureka', phone calls to Guillam, Lacon, 'Smiley is a world champion'. Merely that here before him, in the records he had examined and the notes he had compiled, was the corroboration of a theory which Smiley and Guillam and Ricki Tarr had that day from their separate points of view seen demonstrated: that between the mole Gerald and the Source Merlin there was an interplay that could no longer be denied; that Merlin's proverbial versatility allowed him to function as Karla's instrument as well as Alleline's. Or should he rather say, Smiley reflected - tossing a towel over his shoulder and hopping blithely into the corridor for a celebratory bath - as Karla's agent? And that at the heart of this plot lay a device so simple that it left him genuinely elated by its symmetry. It had even a physical presence: here in London, a house, paid for by the Treasury, all sixty thousand pounds of it; and often coveted, no doubt, by the many luckless taxpayers who daily passed it by, confident they could never afford it and not knowing that they had already paid for it. It was with a lighter heart than he had known for many months that he took up the stolen file on Operation Testify.

To her credit, Matron had been worried about Roach all week, ever since she had spotted him alone in the washroom, ten minutes after the rest of his dormitory had gone down to breakfast, still in his pyjama trousers, hunched over a basin while he doggedly cleaned his teeth. When she questioned him, he avoided her eye. 'It's that wretched father of his,' she told Thursgood. 'He's getting him down again.' And by the Friday: 'You must write to the mother and tell her he's having a spell.'

But not even Matron, for all her motherly perception, would have hit on plain terror as the diagnosis.

Whatever could he do, he a child? That was his guilt. That was the thread that led directly back to the misfortune of his parents. That was the predicament that threw upon his hunched shoulders the responsibility night and day for preserving the world's peace. Roach the watcher - 'best watcher in the whole damn unit', to use Jim Prideaux's treasured words - had finally watched too well. He would have sacrificed everything he possessed, his money, his leather photograph case of his parents, whatever gave him value in the world, if it would buy him release from the knowledge which had consumed him since Sunday evening.

He had put out signals. On Sunday night, an hour after lights out, he had gone noisily to the lavatory, probed his throat, gagged and finally vomited. But the dormitory monitor, who was supposed to wake and raise the alarm - 'Matron, Roach's been sick' - slept stubbornly through the whole charade. Roach clambered miserably back into bed. From the callbox outside the staffroom next afternoon, he had dialled the menu for the day and whispered strangely into the mouthpiece, hoping to be overheard by a master, and taken for mad. No one paid him any attention. He had tried mixing up reality with dreams, in the hope that the event would be converted into something he had imagined; but each morning as he passed the Dip he saw again Jim's crooked figure stooping over the spade in the moonlight; he saw the black shadow of his face under the brim of his old hat, and heard the grunt of effort as he dug.

Roach should never have been there. That also was his guilt: that the knowledge was acquired by sin. After a 'cello lesson on the far side of the village, he had returned to school with deliberate slowness in order to be too late for Evensong, and Mrs Thursgood's disapproving eye. The whole school was worshipping, all but himself and Jim: he heard them sing the Magnificat as he passed the church, taking the long route so that he could skirt the Dip, where Jim's light was glowing. Standing in his usual place, Roach watched Jim's shadow move slowly across the curtained window. He's turning in early, he decided with approval, as the light suddenly went out; for Jim had recently been too absent for his taste, driving off in the Alvis after rugger and not returning till Roach was asleep. Then the caravan door opened and closed and Jim was standing at the vegetable patch with a spade in his hand and Roach in great perplexity was wondering what on earth he should be wanting to dig for in the dark. Vegetables for his supper? For a moment Jim stood stock still, listening to the Magnificat , then glared slowly round and straight at Roach, though he was out of sight against the blackness of the hummocks. Roach even thought of calling to him; but felt too sinful on account of missing chapel.

Finally Jim began measuring. That at least was how it seemed to Roach. Instead of digging he had knelt at one corner of the patch and laid the spade on the earth, as if aligning it with something which was out of sight to Roach: for instance the church spire. This done. Jim strode quickly to where the blade lay, marked the spot with a thud of his heel, took up the spade and dug fast, Roach counted twelve times; then stood back, taking stock again. From the church, silence; then prayers. Quickly stooping, Jim drew a package from the ground, which he at once smothered in the folds of his duffel coat. Seconds later, and much faster than seemed possible, the caravan door slammed, the light went on again, and in the boldest moment of his life Bill Roach tiptoed down the Dip to within three feet of the poorly curtained window, using the slope to give himself the height he needed to look in.

Jim stood at the table. On the bunk behind him lay a heap of exercise books, a vodka bottle and an empty glass. He must have dumped them there to make space. He had a penknife ready but he wasn't using it. Jim would never have cut string if he could avoid it. The package was a foot long and made of yellowy stuff like a tobacco pouch. Pulling it open, he drew out what seemed to be a monkey wrench wrapped in sacking. But who would bury a monkey wrench, even for the best car England ever made? The screws or bolts were in a separate yellow envelope; he spilled them on to the table and examined each in turn. Not screws: pen tops. Not pen tops either; but they had sunk out of sight.

And not a monkey wrench, not a spanner, nothing but absolutely nothing for the car.

Roach had blundered wildly to the brow. He was running between the hummocks, making for the drive, but running slower than he had ever run before; running through sand and deep water and dragging grass, gulping the night air, sobbing it out again, running lopsidedly like Jim, pushing now with this leg, now with the other, flailing with his head for extra speed. He had no thought for where he was heading. All his awareness was behind him; fixed on the black revolver and the bands of chamois leather; on the pen tops that turned to bullets as Jim threaded them methodically into the chamber, his lined face tipped towards the lamplight, pale and slightly squinting in the dazzle.

'I won't be quoted, George,' the Minister warned in his lounging drawl. 'No minutes, no packdrill. I got voters to deal with. You don't. Nor does Oliver Lacon, do you, Oliver?'

He had also, thought Smiley, the American violence with auxiliary verbs: 'Yes, I'm sorry about that,' he said.

'You'd be sorrier still if you had my constituency,' the Minister retorted.

Predictably, the mere question of where they should meet had sparked a silly quarrel. Smiley had pointed out to Lacon that it would be unwise to meet at his room in Whitehall since it was under constant attack by Circus personnel, whether janitors delivering despatch boxes or Percy Alleline dropping in to discuss Ireland. Whereas the Minister declined both the Islay Hotel and Bywater Street on the arbitrary grounds that they were insecure. He had recently appeared on television and was proud of being recognised. After several more calls back and forth they settled for Mendel's semi-detached Tudor residence in Mitcham where the Minister and his shiny car stuck out like a sore thumb. There they now sat, Lacon, Smiley and the Minister, in the trim front room with net curtains and fresh salmon sandwiches, while their host stood upstairs watching the approaches. In the lane, children tried to make the chauffeur tell them who he worked for.
