She glanced at her face in the mirror. It was pale and she quickly rubbed her cheeks to bring back the colour. Then she put back the look of an apologetic secretary and hurried out and ran across the gravel to the car, clutching the notebook among the folds of her coat.

The engine of the Mercedes was turning over. Drax glowered at her impatiently as she scrambled back into her seat.

‘Come on. Come on,’ he said, putting the car into third and taking his foot off the clutch so that she nearly caught her ankle in the heavy door. The tyres churned up the gravel as he accelerated out of the parking place and dry-skidded into the London road.

Gala was jerked back, but she remembered to let the coat with her guilty hand in its folds fall on the seat between her and the driver.

And now the book back into the hip-pocket.

She watched the speedometer hovering in the seventies as Drax flung the heavy car along the crown of the road.

She tried to remember her lessons. Distracting pressure on some other part of the body. Distracting the attention. Distraction. The victim must not be at ease. His senses must be focused away. He must be unaware of the touch on his body. Anaesthetized by a stronger stimulus.

Like now, for instance. Drax, bent forward over the wheel, was fighting for a chance to get past a sixty-foot R.A.F. trailer, but the oncoming traffic was leaving no room on the crown of the road. There was a gap and Drax rammed the lever into second and took it, his horns braying imperiously.

Gala’s hand reached to the left under the coat.

But another hand struck like a snake.

‘Got you.’

Krebs was leaning half over the back of the driving seat. His hand was crushing hers into the slippery cover of the notebook under the folds of the coat.

Gala sat frozen into black ice. With all her strength she wrenched at her hand. It was no good. Krebs had all his weight on it now.

Drax had got past the trailer and the road was empty. Krebs said urgently in German, ‘Please stop the car, mein Kapitän. Miss Brand is a spy.’

Drax gave a startled glance to his right. What he saw was enough. He put his hand quickly down to his hip-pocket, and then, slowly, deliberately, put it back on the wheel. The sharp turning to Mereworth was just coming up on his left. ‘Hold her,’ said Drax. He braked so that the tyres screamed, changed down and wrenched the car into the side-road. A few hundred yards down it he pulled the car into the side and stopped.

Drax looked up and down the road. It was empty. He reached over one gloved hand and wrenched Gala’s face towards him.

‘What is this?’

‘I can explain it, Sir Hugo.’ Gala tried to bluff against the horror and desperation she knew was in her face. ‘It’s a mistake. I didn’t mean … ’

Under cover of an angry shrug of the shoulders, her right hand moved softly behind her and the guilty pair of gloves were thrust behind the leather cushion.

‘Sehen sie her, mein Kapitän. I saw her edging up close to you. It seemed to me strange.’

With his other hand Krebs had whipped the coat away and there were the bent white fingers of her left hand crushed into the cover of the notebook still a foot away from Drax’s hip-pocket.

‘So.’

The word was deadly cold and with a shivering finality.

Drax let go her chin, but her horrified eyes remained locked into his.

A kind of frozen cruelty was showing through the jolly façade of red skin and whiskers. It was a different man. The man behind the mask. The creature beneath the flat stone that Gala Brand had lifted.

Drax glanced again up and down the empty road.

Then, looking carefully into the suddenly aware blue eyes, he drew the leather driving gauntlet off his left hand and with his right whipped her as hard as he could across the face with it.

Only a short cry was forced out of Gala’s constricted throat, but tears of pain ran down her cheeks. Suddenly she began to fight like a madwoman.

With all her strength she heaved and fought against the two iron arms that held her. With her free right hand she tried to reach the face that leant over her hand and get at the eyes. But Krebs easily moved his head out of her reach and quietly increased the pressure across her throat, hissing murderously to himself as her nails tore strips of skin off the backs of his hands, but noting with a scientist’s eye as her struggles became weaker.

Drax watched carefully, with one eye on the road, as Krebs brought her under control and then he started the car and drove cautiously on along the wooded road. He grunted with satisfaction as he came upon a cart-track into the woods and he turned up it and only stopped when he was well out of sight of the road.

Gala had just realized that there were no noise from the engine when she heard Drax say ‘there’. A finger touched her skull behind the left ear. Krebs’s arm came away from her throat and she slumped gratefully forward, gasping for air. Then something crashed into the back of her head where the finger had touched it, and there was a flash of wonderfully releasing pain and blackness.

An hour later passers-by saw a white Mercedes draw up outside a small house at the Buckingham Palace end of Ebury Street and two kind gentlemen help a sick girl out and through the front door. Those who were near could see that the poor girl’s face was very pale and that her eyes were shut and that the kind gentlemen almost had to carry her up the steps. The big gentleman with the red face and whiskers was heard to say quite distinctly to the other man that poor Mildred had promised she wouldn’t go out until she was quite well again. Very sad.

Gala came to herself in a large top-floor room that seemed to be full of machinery. She was tied very securely to a chair and apart from the searing pain in her head she could feel that her lips and cheek were bruised and swollen.

Heavy curtains were drawn across the window and there was a musty smell in the room as if it was rarely used. There was dust on the few pieces of conventional furniture and only the chromium and ebonite dials on the machines looked clean and new. She thought that she was probably in hospital. She closed her eyes and wondered. It was not long before she remembered. She spent several minutes controlling herself and then she opened her eyes again.

Drax, his back to her, was watching the dials on a machine that looked like a very large radio set. There were three more similar machines in her line of sight and from one of them a thin steel aerial reached up to a rough hole that had been cut for it in the plaster of the ceiling. The room was brightly lit by several tall standard lamps, each of which held a naked high wattage bulb.

To her left there was a noise of tinkering and by swivelling her half-closed eyes in their sockets, which made the pain in her head much worse, she saw the figure of Krebs bent over an electric generator on the floor. Beside it there was a small petrol engine and it was this that was giving trouble. Every now and then Krebs would grasp the starting-handle and crank it hard and a feeble stutter would come from the engine before he went back to his tinkering.

‘You dam’ fool,’ said Drax in German, ‘hurry up. I’ve got to go and see those bloody oafs at the Ministry.’

‘At once, mein Kapitän,’ said Krebs dutifully. He seized the handle again. This time after two or three coughs the engine started up and began to purr.

‘It won’t make too much noise?’ asked Drax.

‘No, mein Kapitän. The room has been soundproofed,’ answered Krebs. ‘Dr. Walter assures me that nothing will be heard outside.’

Gala closed her eyes and decided that her only hope was to feign unconsciousness for as long as possible. Did they intend to kill her? Here in this room? And what was all this machinery? It looked like wireless, or perhaps radar. That curved glass screen above Drax’s head that had given an occasional flicker as Drax fiddled with the knobs below the dials.
