Cazolet rolled over and waved his hands in front of his eyes, trying to ward off the light from the bare bulb which was prying his lids apart. He spent a great deal of his time in the Annexe and the result was a grey pallor across his face made worse by lack of sleep. He wasn’t supposed to be on duty at the moment, but he knew the PM’s mind so well that the other staff had taken to consulting him on many matters. What it meant, of course, was that they brought him all their problems, as if he didn’t have several filing trays full of his own to deal with. But he didn’t mind; consultation was the finest form of bureaucratic flattery.

‘Seems there’s been a break-out. Some POW transit camp in Yorkshire. Haven’t got the final figures but it looks like – almost two hundred and fifty Jerry on the loose. I’ve double-checked, of course. No doubt about it, I’m afraid. Bit of a cock-up, really.’ Seizall’s sentences were clipped, giving but the barest detail, as if too much flavour might somehow involve him in it all, and every instinct in his civil service body told him to steer well clear of this one.

‘I was just about to let the Old Man know,’ Seizall continued. ‘Trouble is he’s fast asleep; got in dreadfully late last night from some swill of a dinner party and you know he’s like a rhinoceros with piles when he’s woken. So I thought I’d let him sleep on a little. Trouble is I’ve got to inform all the other necessary Departments … What’ll we do?’

‘So all of a sudden it’s our problem, is it?’ Cazolet grumbled. One day, one day very soon, he prayed, they would let him get a full night’s sleep. He poured cold water from a large jug into an enamel washbasin – all that passed for facilities in the primitive subterranean accommodation – splashing urgent handfuls over his face to encourage a little more oxygen into his brain while Seizall stood uncomfortably in the doorway of the narrow room. The cold water seemed to have worked, for when Cazolet stood up from the wash-stand he was decisive.

‘You tell all the other Departments, Seizall, and the news will be round Fleet Street before you’ve had time to finish breakfast. And once that’s out, we’ll never be able to put it back in the bag, wartime censorship or no. It’ll be blaring out on Radio Berlin within five minutes. Two hundred and fifty of them? It’s a disaster. And it’s just what the Prime Minister’s political opponents want. They’ll pin the blame for slack security on him personally, try to make him look old and incompetent. So you go right ahead and inform everyone from the Labour Party to the Third Reich that we have one of the biggest security lash-ups of the war on our hands.’ He paused to dry his face vigorously with a rough cotton towel. ‘Then you can go wake up the PM and tell him what you’ve done.’

The effect on Seizall was impressive. His lower jaw wobbled in fair impression of a mullet, his Adam’s apple performing balletic gyrations of distress.

‘There is a better way,’ Cazolet continued, his supremacy in the matter clearly established. ‘We tell the minimum number of people – only those in the security services who need to know in order to start getting Jerry rounded up. We make it clear to them that this is a matter of top national security, that any public discussion of the escape can only give comfort to the enemy. Be vague about numbers. Then, when the Old Man’s awake and in harness, we’ll tell him what we’ve done. If he wants to let the whole world know, he can. But that’s up to him, not you or me.’

Seizall was nodding, trying to look as if he were merely accepting endorsement of a course of action he had already made up his mind to pursue.

‘There’s a lot riding on this, Seizall. Perhaps the Old Man’s entire political future. I think he’ll be grateful you waited.’

For the first time that morning an impression of relief began to etch its way across the duty secretary’s face and he paused to give silent thanks for the binding effect of powdered egg.

Dawn was beginning to paint lurid pictures in the sky, thin fingers of rain cloud stretching towards him like witches’ claws, their fire-red tips making the heavens appear to drip with blood. Around Hencke the dark woods seemed to crowd in, the trees bending down as if trying to pluck him from the seat of his bike while the throbbing of the engine surrounded him in a cocoon of sound which carved out a little world of his own and detached him from reality. From the moment he had scattered the commander’s letter to the wind he had kept his head low and the throttle stretched open, taking full advantage of the deserted roads. The wind snatched at his hair and froze his face and fingertips, all the while urging him onwards. He was free! But there was no elation in Hencke. As he looked at the fierce sky above him, the memories came crowding back. In the glow that brushed the clouds he saw only the embers he had found burning in the schoolhouse, consuming everything he loved. In the gloom of the trees bowing and sagging in the wind he found images of the veils pulled close around the mothers who had come to sorrow and mourn, weighed down by incomprehension at their loss. In the thumping noise of the engine there was no sound of freedom, only the tramp of boots as they had marched past smouldering wreckage. Hencke could not escape the memory of young bodies twisted and broken. Of books torn and burning, their ashes scattered in the growing winds of war. Of a pair of tiny shoes lying neatly at the entrance to the classroom, with no trace of the vibrant and joyful child who had been wearing them moments before. Of a love which should never have been and which could never be again. And as he remembered he clung to the throttle like a drowning man clutches at a stick, charging recklessly onward, pursued by demons.

As the sky began to lose its lustre and take on the damp grey tones of March he found himself passing through more open countryside. The long avenues of haunted trees made way for the hedgerows of rural England; above the whistle of the wind he could hear the welcoming chorus of early morning, and the demons that had returned to haunt his mind faded in the daylight. They would be back, they always came back, yet for a moment the nightmare seemed to have drained from his soul. He was taking the first, deep breath of relief when he rounded a long bend between the hedgerows and stood hard on the brake pedal, sliding to a halt on the dewy surface. Before him, stretched full across the road and blocking his path, was a rusty farm tractor around which spilled a line of British soldiers, rifles raised, pointing directly at him.

It seemed as if his race was already over.

It was nearly eleven o’clock before Cazolet presented himself to the Marine guard stationed outside the Prime Minister’s bedroom. As the sentry stepped smartly aside, Cazolet entered bearing a large cup of tea. Churchill stirred beneath the thick quilt. Typically he slept heavily and late, particularly after a good dinner, but five years of heartbreak and Hitler had conditioned him to come rapidly to full alert.

‘William. To what do I owe this decidedly ambiguous pleasure?’ He swept the dishevelled strands of greying russet hair back into place and reached out greedily for the tea, which he proceeded to slurp.

‘There’s been a POW break-out.’

‘From where?’

‘Yorkshire. Camp 174B. It’s just north of …’

‘Yes. I know it,’ Churchill interrupted, the tea temporarily forgotten. There was a gleam – a twinkle, even – in the Old Man’s eye. ‘Some men never seem to know when they’re beaten. How many?’

‘Nearly two hundred and fifty.’

Churchill jumped. The tea slopped into the saucer and began dripping onto the sheet.

‘Nearly two hundred and fifty,’ Cazolet repeated. ‘Several thousand troops are being sent to the area, but as always they’re in the wrong place, waiting on the south coast to embark for Europe. To fill the gap we’ve activated detachments of the local Home Guard to man road blocks around the camp.’
