Smiley shrugged it all aside, distrustful as ever of the standard shapes of human motive, and settled instead for a picture of one of those wooden Russian dolls that open up, revealing one person inside the other, and another inside him. Of all men living, only Karla had seen the last little doll inside Bill Haydon. When was Bill recruited, and how? Was his right- wing stand at Oxford a pose, or was it paradoxically the state of sin from which Karla summoned him to grace?

Ask Karla: pity I didn't.

Ask Jim: I never shall.

Over the flat East Anglian landscape as it slid slowly by, the unyielding face of Karla replaced Bill Haydon's crooked deathmask. 'But you had this one price: Ann. The last illusion of the illusionless man. He reckoned that if I were known to be Ann's lover around the place you wouldn't see me very straight when it came to other things.'

Illusion? Was that really Karla's name for love? And Bill's?

'Here,' said the guard very loudly, and perhaps for the second time. 'Come on with it, you're for Grimsby then, aren't you?'

'No, no: Immingham.' Then he remembered Mendel's instructions and clambered on to the platform.

There was no cab in sight, so having enquired at the ticket office, he made his way across the empty forecourt and stood beside a green sign marked 'Queue'. He had hoped she might collect him, but perhaps she hadn't received his wire. Ah well; the post office at Christmas: who could blame them? He wondered how she would take the news about Bill; till, remembering her frightened face on the cliffs in Cornwall, he realised that by then Bill was already dead for her. She had sensed the coldness of his touch, and somehow guessed what lay behind it.

Illusion? he repeated to himself. Illusionless?

It was bitterly cold; he hoped very much that her wretched lover had found her somewhere warm to live.

He wished he'd brought her fur boots from the cupboard under the stairs.

He remembered the copy of Grimmelshausen, still uncollected at Martindale's club.

Then he saw her: her disreputable car shunting towards him down the lane marked 'Buses only' and Ann at the wheel staring the wrong way. Saw her get out, leaving the indicator winking, and walk into the station to enquire: tall and puckish, extraordinarily beautiful, essentially another man's woman.

For the rest of that term, Jim Prideaux behaved in the eyes of Roach much as his mother had behaved when his father went away. He spent a lot of time on little things, like fixing up the lighting for the school play and mending the soccer nets with string, and in French he took enormous pains over small inaccuracies. But big things, like his walks and solitary golf, these he gave up altogether, and in the evenings stayed in and kept clear of the village. Worst of all was his staring, empty look when Roach caught him unawares, and the way he forgot things in class, even red marks for merit: Roach had to remind him to hand them in each week.

To support him, Roach took the job of dimmer man on the lighting. Thus at rehearsals Jim had to give him a special signal, to Bill and no one else. He was to raise his arm and drop it to his side, when he wanted the footlights to fade.

With time, Jim seemed to respond to treatment, however. His eye grew clearer and he became alert again, as the shadow of his mother's death withdrew. By the night of the play he was more light- hearted than Roach had ever known him. 'Hey Jumbo you silly toad, where's your mac, can't you see it's raining?' he called out, as tired but triumphant they trailed back to the main building after the performance. 'His real name is Bill,' he heard him explain to a visiting parent. 'We were new boys together.'

The gun, Bill Roach had finally convinced himself, was after all a dream.
