‘So you agree with Aranda then, Comrade Stalin is a coward?’

‘I don’t know why he made the pact. No more than you do.’

‘He is right. This is an imperialist war.’

‘It’s a war against fascism. That’s what I fought for in 1936. Go away, Establo, I would not argue with a sick man.’ Bernie glanced at Pablo. His face was drawn with pain, one hand on the bedrail to support himself even as his other hand supported Establo.

‘One day,’ Establo said quietly, ‘when the Soviets have won, you will wish you had kept your faith. I will not be here to denounce you as an enemy of the working class, but others will.’ He jerked his head at Pablo. ‘These people will be my memory.’

‘Yes, comrade.’ Bernie rose from the bed. He had to bring this to a halt. ‘I have to piss, if you will excuse me.’ He walked to the door then went round the side of the hut and relieved himself. He looked through the barbed wire at the white landscape beyond. Let there be no moon that night, he thought. Then he jumped, almost cried out, at a hand on his shoulder. He whirled round. Agustín was standing there.

‘What the fuck are you doing?’ he whispered angrily.

‘I have been waiting an hour, waiting to see if you would come out.’ Agustín took a deep breath. ‘The shifts have been changed. I am being made to take Saturday off. We cannot go.’

HILLGARTH AND TOLHURST were due at Harry’s flat at seven, Sandy at half past. When Tolhurst told Harry he would be accompanying Hillgarth, his face had flushed with pride. ‘The captain’s asked me to come and help this time as I know all about it,’ he said self-importantly, as though Harry cared.

When Harry got home from the embassy late that afternoon the flat was bitterly cold. It hadn’t snowed again but there was a heavy frost, thick fingers of ice on the window. He lit the brasero and went into the kitchen and he put his keys in the little saucer where he kept them. They had been in his overcoat and the metal was cold. He remembered a line from Richard III – he had helped produce the play at school: Gloucester seeking assurance the Duke of Clarence was dead and being told he was ‘key-cold’.

He went into the salón and straightened one of the watercolours. Waiting was the worst part. There would be a lot of it between now and Saturday when they went to Cuenca.

The room held the faint tang of Sofia’s scent. Strange how scent smelt musky in warm air, tangy in cold. The two of them had sat up most of last night, talking about the rescue. What they were doing was a serious offence. If they were caught there would be diplomatic immunity for him and protection for Barbara, but Sofia was Spanish and it could mean a long prison sentence. Harry had spent half the evening trying to dissuade her from coming, but she was adamant.

‘I faced enough danger during the Siege,’ she said. ‘If I’m going to leave my country at least I can do one good thing, rescue one person.’

‘Bernie’s important to me – I wouldn’t do it otherwise. But you don’t owe him anything.’

‘I owe all the people who came out here to help the Republic. I want to do something before I leave.’ She smiled sadly. ‘Does that sound very romantic and Spanish and stupid?’

‘No, no. It’s something clean.’ He wondered for a moment if she wanted to see if he too was capable of something clean, after the murk he had been involved in, the betrayals. He had told Barbara he would help, partly because his heart had leapt at the news Bernie was alive, partly to make up for his lies, but also to show Sofia he could do something good. Something had changed between them; a slight withdrawing on her part, a tiny hesitation only a lover would have noticed.

She hadn’t hesitated though when Harry told her he had arranged for them to be married at the embassy. It would be a civil ceremony as he wasn’t a Catholic, but the embassy could do that, perform a marriage according to English laws. Tolhurst had had a word in certain quarters, smoothed the wheels.

‘The only thing that worries me,’ he said, ‘is whether Barbara is strong enough for this.’

‘I think she is. She’s brought it this far alone. This Bernie, he must be very special. Most of the Spanish Communists were bad people.’

‘He was my best friend. Bernie would never let you down, he was like a rock.’ Not like me, he thought. ‘And how he stuck to his socialism.’ He laughed softly. ‘It didn’t go down well at Rookwood, I can tell you.’ He smiled wryly. ‘Paco must never go to one of those public schools. Either you rebel, or they send you sleepwalking through life.’

THE DOORBELL rang shrilly, bringing Harry out of his reverie. He took a deep breath and went to open it. Hillgarth and Tolhurst stood together in trilbies and thick overcoats. He invited them in and took their coats and hats. Underneath they wore smart suits. Hillgarth rubbed his hands.

‘God, Brett, it’s cold in here.’

‘It takes a while to warm up. Would you like a drink?’

He poured whisky for Hillgarth, brandy for Tolhurst and himself. He looked at his watch: a quarter to seven. Tolhurst sat down on the sofa, looking nervous. Hillgarth walked round the room, examining the pictures. ‘These from the embassy?’

‘Yes, the walls were bare when I came.’

‘Find any souvenirs of that Communist who had it before?’ He smiled. ‘Any directives from Moscow down the backs of the chairs?’

‘No, nothing at all.’

‘Franco’s people would have picked the place clean. By the way, you’re still not being followed, are you?’

‘No. Not for weeks now.’

‘They must have decided you’re too junior.’

God, Harry thought, the things he was keeping from them; and that was nothing to what he was going to do on Saturday. He mustn’t think about that, he must stay cool. Key-cold.

‘By the way,’ Tolhurst said, ‘your fiancée needs to come for an interview at the embassy tomorrow. Just for political vetting, to make sure she’s not a Franco agent. I can brief you on what she should say.’

‘OK. Thanks.’

‘The little boy should be OK,’ Tolhurst continued, ‘but she’ll need to prove she’s been looking after him.’ He looked at Harry with that serious, owlish expression of his.

‘She collects his rations, has done for a year and a half.’

He nodded. ‘That should do.’

Hillgarth looked between them, nursing his drink. ‘You should be grateful to Tolly, Brett. He was over in immigration half yesterday afternoon.’

The doorbell rang again, a sharp peal. For a second all three stood silent, as though gathering their resources. Then Hillgarth said, ‘Let him in, Brett.’

Sandy was outside, slouching, smiling. ‘Hello, Harry.’ He looked over Harry’s shoulder. ‘They here?’

‘Yes. Come on through.’

He led him into the salón. Sandy nodded at Hillgarth and Tolhurst, then looked round the room. ‘Nice flat. See you’ve got some English pictures.’

Hillgarth stepped forward, extending a hand. ‘Captain Alan Hillgarth. This is Simon Tolhurst.’

‘Pleased to meet you.’

‘Drink, Sandy?’ Harry asked.

‘Whisky, please.’ He looked at the bottle on the sideboard. ‘Oh, you’ve got Glenfiddich. I wonder if your supplier’s the same as mine. Little black-market place behind the Rastro?’

‘Embassy supplies, actually,’ Hillgarth said. ‘Straight from England. Perk of the job.’

‘Home comforts, eh?’ Sandy gave Harry his broad smile as he took his drink. Harry squirmed inwardly.

‘Shall we sit down?’ Hillgarth asked.

‘Of course.’ Sandy took a seat, offering his silver cigarette case to Hillgarth. ‘Smoke?’

‘Thanks.’ Sandy offered one to Tolhurst. ‘I know Harry doesn’t,’ he said, snapping the case shut. He leaned back in his chair. ‘So. What can I do for you?’

‘We’ve been keeping an eye on you, Forsyth,’ Hillgarth said smoothly. ‘We know about your involvement in the mine out beyond Segovia, we know it’s a big project and you’ve been having trouble with Colonel Maestre’s committee. We believe his Monarchist faction want to wrest control of a major resource from the Falangists at the Ministry of Mines.’
