Smiley drove to Taunton and from the Castle Hotel made a string of telephone calls. Though exhausted he slept fitfully between visions of Karla sitting at Jim's table with two crayons, and Cultural Attaché Polyakov alias Viktorov, fired by concern for the safety of his mole Gerald, waiting impatiently in the interrogation cell for Jim to break. Lastly of Toby Esterhase bobbing into Sarratt in place of the absent Haydon, cheerfully advising Jim to forget all about Tinker, Tailor, and his dead inventor, Control.

The same night Peter Guillam drove west, clean across England to Liverpool, with Ricki Tarr as his only passenger. It was a tedious journey in beastly conditions. For most of it Tarr boasted about the rewards he would claim, and the promotion, once he had carried out his mission. From there he talked about his women: Danny, her mother, Irina. He seemed to envisage a ménage à quatre in which the two women would jointly care for Danny, and for himself.

'There's a lot of the mother in Irina. That's what frustrates her, naturally.' Boris, he said, could get lost, he would tell Karla to keep him. As their destination approached, his mood changed again and he fell silent. The dawn was cold and foggy. In the suburbs they had to drop to a crawl and cyclists overtook them. A reek of soot and steel filled the car.

'Don't hang about in Dublin, either,' said Guillam suddenly. 'They expect you to work the soft routes so keep your head down. Take the first plane out.' 'We've been through all that.'

'Well I'm going through it all again,' Guillam retorted. 'What's Mackelvore's workname?'

'For Christ's sake,' Tarr breathed, and gave it.

It was still dark when the Irish ferry sailed. There were soldiers and police everywhere: this war, the last, the one before. A fierce wind was blowing off the sea and the going looked rough. At the dockside, a sense of fellowship briefly touched the small crowd as the ship's lights bobbed quickly into the gloom. Somewhere a woman was crying, somewhere a drunk was celebrating his release.

He drove back slowly, trying to work himself out: the new Guillam who starts at sudden noises, has nightmares and not only can't keep his girl but makes up crazy reasons for distrusting her. He had challenged her about Sand, and the hours she kept, and about her secrecy in general. After listening with her grave brown eyes fixed on him she told him he was a fool, and left. 'I am what you think I am,' she said, and fetched her things from the bedroom. From his empty flat he telephoned Toby Esterhase, inviting him for a friendly chat later that day.

Smiley sat in the Minister's Rolls, with Lacon beside him. In Ann's family the car was called the black bed-pan, and hated for its flashiness. The chauffeur had been sent to find himself breakfast. The Minister sat in the front and everyone looked forward down the long bonnet, across the river to the foggy towers of Battersea Power Station. The Minister's hair was full at the back, and licked into small black horns around the ears.

'If you're right,' the Minister declared, after a funereal silence, 'I'm not saying you're not, but if you are, how much porcelain will he break at the end of the day?'

Smiley did not quite understand.

'I'm talking about scandal. Gerald gets to Moscow. Right, so then what happens? Does he leap on a soapbox and laugh his head off in public about all the people he's made fools of over here? I mean Christ, we're all in this together, aren't we? I don't see why we should let him go just so's he can pull the bloody roof down over our heads and the competition sweep the bloody pool.'

He tried a different tack. 'I mean to say, just because the Russians know our secrets doesn't mean everyone else has to. We got plenty of other fish to fry apart from them, don't we? What about all the black men: are they going to be reading the gory details in the Wallah-Wallah News in a week's time?'

Or his constituents, Smiley thought.

'I think that's always been a point the Russians accept,' said Lacon. 'After all, if you make your enemy look a fool, you lose the justification for engaging him.' He added: They've never made use of their opportunities so far, have they?'

'Well, make sure they toe the line. Get it in writing. No, don't. But you tell them what's sauce for the goose is sauce for the gander. We don't go round publishing the batting order at Moscow Centre, so they can bloody well play ball too, for once.'

Declining a lift, Smiley said the walk would do him good.

It was Thursgood's day for duty and he felt it badly. Headmasters, in his opinion, should be above the menial tasks, they should keep their minds clear for policy and leadership. The flourish of his Cambridge gown did not console him, and as he stood in the gymnasium watching the boys file in for morning line-up, his eye fixed on them balefully, if not with downright hostility. It was Marjoribanks, though, who dealt the deathblow.

'He said it was his mother,' he explained, in a low murmur to Thursgood's left ear. 'He'd had a telegram and proposed to leave at once. He wouldn't even stay for a cup of tea. I promised to pass on the message.'

'It's monstrous, absolutely monstrous,' said Thursgood.

'I'll take his French if you like. We can double up Five and Six.'

'I'm furious,' said Thursgood. 'I can't think, I'm so furious.'

'And Irving says he'll take the rugger final.'

'Reports to be written, exams, rugger finals to play off. What's supposed to be the matter with the woman? Just a flu, I suppose, a seasonal flu. Well we've all got that, so have our mothers. Where does she live?'

'I rather gathered from what he said to Sue that she was dying.'

'Well that's one excuse he won't be able to use again,' said Thursgood, quite unmollified, and with a sharp bark quelled the noise and read the roll.

'Roach?'

'Sick, sir.'

That was all he needed to fill his cup. The school's richest boy having a nervous breakdown about his wretched parents, and the father threatening to remove him.

It was almost four o'clock on the afternoon of the same day. Safe houses I have known, thought Guillam, looking round the gloomy flat. He could write of them the way a commercial traveller could write about hotels: from your five-star hall of mirrors in Belgravia with Wedgwood pilasters and gilded oak-leaves, to this two-room scalphunters' shakedown in Lexham Gardens, smelling of dust and drains, with a three-foot fire extinguisher in the pitch-dark hall. Over the fireplace, cavaliers drinking out of pewter. On the nest of tables, sea shells for ashtrays, and in the grey kitchen, anonymous instructions to Be Sure and Turn Off the Gas Both Cocks. He was crossing the hall when the house bell rang, exactly on time. He lifted the phone and heard Toby's distorted voice howling in the earpiece. He pressed the button and heard the clunk of the electric lock echoing in the stairwell. He opened the front door but left it on the chain till he was sure Toby was alone.

'How are we?' said Guillam cheerfully, letting him in. 'Fine actually, Peter,' said Toby, pulling off his coat and gloves.

There was tea on a tray: Guillam had prepared it, two cups. To safe houses belongs a certain standard of catering. Either you are pretending you live there, or that you are adept anywhere; or simply that you think of everything. In the trade, naturalness is an art, Guillam decided. That was something Camilla could not appreciate.

'Actually it's quite strange weather,' Esterhase announced, as if he had really been analysing its qualities. Safe house small talk was never much better. 'One walks a few steps and is completely exhausted already. So we are expecting a Pole?' he said, sitting down. 'A Pole in the fur trade who you think might run courier for us?'

'Due here any minute.'

'Do we know him? I had my people look up the name but they found no trace.'

My people, thought Guillam: I must remember to use that one. 'The Free Poles made a pass at him a few months back and he ran a mile,' he said. 'Then Karl Stack spotted him round the warehouses and thought he might be useful to the scalphunters.' He shrugged. 'I liked him but what's the point? We can't even keep our own people busy.'

'Peter, you are very generous,' said Esterhase reverently, and Guillam had the ridiculous feeling he had just tipped him. To his relief the front-door bell rang and Fawn took up his place in the doorway.

'Sorry about this, Toby,' Smiley said, a little out of breath from the stairs. 'Peter, where shall I hang my coat?'

Turning him to the wall, Guillam lifted Toby's unresisting hands and put them against it, then searched him for a gun, taking his time. Toby had none.

'Did he come alone?' Guillam asked. 'Or is there some little friend waiting in the road?'

'Looked all clear to me,' said Fawn.

Smiley was at the window, gazing down into the street. 'Put the light out a minute, will you?' he said.

'Wait in the hall,' Guillam ordered, and Fawn withdrew, carrying Smiley's coat. 'Seen something?' he asked Smiley, joining him at the window.

Already the London afternoon had taken on the misty pinks and yellows of evening. The square was Victorian residential; at the centre, a caged garden, already dark. 'Just a shadow, I suppose,' said Smiley with a grunt, and turned back to Esterhase. The clock on the mantelpiece chimed four. Fawn must have wound it up.

'I want to put a thesis to you, Toby. A notion about what's going on. May I?' Esterhase didn't move an eyelash. His little hands rested on the wooden arms of his chair. He sat quite comfortably, but slightly to attention, toes and heels of his polished shoes together.

'You don't have to speak at all. There's no risk to listening, is there?'

'Maybe.'

'It's two years ago. Percy Alleline wants Control's job, but he has no standing in the Circus. Control has made sure of that. Control is sick and past his prime but Percy can't dislodge him. Remember the time?'

Esterhase gave a neat nod.

'One of those silly seasons,' said Smiley in his reasonable voice. 'There isn't enough work outside so we start intriguing around the service, spying on one another. Percy's sitting in his room one morning with nothing to do. He has a paper appointment as operational director, but in practice he's a rubber stamp between the regional sections and Control, if that. Percy's door opens and somebody walks in. We'll call him Gerald, it's just a name. "Percy," he says, "I've stumbled on a major Russian source. It could be a gold mine." Or perhaps he doesn't say anything till they're outside the building, because Gerald is very much a field man, he doesn't like to talk with walls and telephones around. Perhaps they take a walk in the park or a drive in a car. Perhaps they eat a meal somewhere, and at this stage there isn't much Percy can do but listen. Percy's had very little experience of the European scene, remember, least of all Czecho or the Balkans. He cut his teeth in South America and after that he worked the old possessions: India, the Middle East. He doesn't know a lot about Russians or Czechs or what you will, he's inclined to see red as red and leave it at that. Unfair?'
