He had heard her stumble on the stairs. If she'd waited another minute he would have had the radio transmitter back in its case and the code books in the drawer and there would have been no need for her to die. But before he could conceal the evidence he had heard her key in the lock, and when she opened the door the stiletto had been in his hand. Because she moved slightly in his arms, Faber missed her heart with the first jab of the weapon, and he had to thrust his fingers down her throat to stop her crying out. He jabbed again, but she moved again and the blade struck a rib and merely slashed her superficially. Then the blood was spurting and he knew it would not be a clean kill; it never was when you missed with the first stroke. She was wriggling too much to be killed with a jab now. Keeping his fingers in her mouth, he gripped her jaw with his thumb and pushed her back against the door. Her head hit the woodwork with a loud bump, and he wished he had not turned the radio down, but how could he have expected this?

He hesitated before killing her because it would be much better if she died on the bed-better for the cover-up that was already taking shape in his mind-but he could not be sure of getting her that far in silence. He tightened his hold on her jaw, kept her head still by jamming it against the door, and brought the stiletto around in a wide, slashing arc that ripped away most of her throat, for the stiletto was not a slashing knife and the throat was not Faber's favoured target.

He jumped back to avoid the first horrible gush of blood, then stepped forward again to catch her before she hit the floor. He dragged her to the bed, trying not to look at her neck, and laid her down.

He had killed before, so he expected the reaction; it always came as soon as he felt safe. He went over to the sink in the corner of the room and waited for it. He could see his face in the little shaving mirror. He was white and his eyes were staring. He looked at himself and thought, killer. Then he threw up.

When that was over he felt better. He could go to work now. He knew what he had to do, the details had come to him even while he was killing her.

He washed his face, brushed his teeth and cleaned the washbasin. Then he sat down at the table beside his radio. He looked at his notebook, found his place and began tapping the key. It was a long message, about the mustering of an army for Finland, and he had been halfway through when he was interrupted. It was written down in cipher on the pad. When he had completed it he signed off with "Regards to Willi."

The transmitter packed away neatly into a specially designed suitcase. Faber put the rest of his possessions into a second case. He took off his trousers and sponged the bloodstains, then washed himself all over. At last he looked at the corpse.

He was able to be cold about her now. It was wartime; they were enemies; if he had not killed her she would have caused his death. She had been a threat, and all he felt now was relief that the threat had been nullified. She should not have frightened him.

Nevertheless, his last task was distasteful. He opened her robe and lifted her nightdress, pulling it up around her waist. She was wearing knickers. He tore them, so that the hair of her pubis was visible. Poor woman, she had wanted only to seduce him. But he could not have got her out of the room without her seeing the transmitter, and the British propaganda had made these people alert for spies-ridiculously so. If the Abwehr had as many agents as the newspapers made out, the British would have lost the war already.

He stepped back and looked at her with his head on one side. There was something wrong. He tried to think like a sex maniac. If I were crazed with lust for a woman like Una Garden, and I killed just so that I could have my way with her. what would I then do?

Of course. That kind of lunatic would want to look at her breasts. Faber leaned over the body, gripped the neckline of the nightdress, and ripped it to the waist. Her large breasts sagged sideways.

The police doctor would soon discover that she had not been raped, but Faber did not think that mattered. He had taken a criminology course at Heidelberg, and he knew that many sexual assaults were not consummated. Besides, he could not have carried the deception that far, not even for the Fatherland. He was not in the SS. Some of them would queue up to rape the corpse… He put the thought out of his mind.

He washed his hands again and got dressed. It was almost midnight. He would wait an hour before leaving; it would be safer later. He sat down to think about how he had gone wrong.

There was no question that he had made a mistake. If his cover were perfect, he would be totally secure. If he were totally secure no one could discover his secret. Mrs Garden had discovered his secret-or rather, she would have if she had lived a few seconds longer-therefore he had not been totally secure, therefore his cover was not perfect, therefore he had made a mistake.

He should have put a bolt on the door. Better to be thought chronically shy than to have landladies with duplicate keys sneaking in in their nightclothes.

That was the surface error. The deep flaw was that he was too eligible to be a bachelor. He thought this with irritation, not conceit. He knew that he was a pleasant attractive man and that there was no apparent reason why he should be single. He turned his mind to thinking up a cover that would explain this without inviting advances from the Mrs Gardens of this world.

He ought to be able to find inspiration in his real personality. Why was he single? He stirred uneasily. He did not like mirrors. The answer was simple. He was single because of his profession. If there were deeper reasons, he did not want to know them.

He would have to spend tonight in the open. Highgate Wood would do. In the morning he would take his suitcases to a railway station checkroom, then tomorrow evening he would go to his room in Blackheath.

He would shift to his second identity. He had little fear of being caught by the police. The commercial traveller who occupied the room at Blackheath on weekends looked rather different from the railway clerk who had killed his landlady.

The Blackheath persona was expansive, vulgar, and flashy. He wore loud ties, bought rounds of drinks, and combed his hair differently. The police would circulate a description of a shabby little pervert who would not say boo to a goose until he was inflamed with lust, and no one would look twice at the handsome salesman in the striped suit who was obviously the type that was more or less permanently inflamed with lust and did not have to kill women to get them to show him their breasts. He would have to set up another identity-he always kept at least two. He needed a new job, fresh papers, passport, identity card, ration book, birth certificate. It was all so risky. Damn Mrs Garden. Why couldn't she have drunk herself asleep as usual?

It was one o'clock. Faber took a last look around the room. He was not concerned about leaving clues-his fingerprints were obviously all over the house, and there would be no doubt in anyone's mind about who was the murderer. Nor did he feel any sentiment about leaving the place that had been his home for two years; he had never thought of it as home. He had never thought of anywhere as home.

He would always think of this as the place where he had learned to put a bolt on a door.

He turned out the light, picked up his cases, and went down the stairs and out of the door into the night.

Henry II was a remarkable king. In an age when the term "flying visit" had not yet been coined, he flitted between England and France with such rapidity that he was credited with magical powers; a rumour that, understandably, he did nothing to suppress. In 1173-either the June or the September, depending upon which secondary source one favours-he arrived in England and left for France again so quickly that no contemporary writer ever found out about it. Later historians discovered the record of his expenditure in the Pipe Rolls. At the time his kingdom was under attack by his sons at its northern and southern extremes: the Scottish border and the South of France. But what, precisely, was the purpose of his visit? Whom did he see? Why was it secret, when the myth of his magical speed was worth an army? What did he accomplish?
