It was drudgery, but he managed to give it an individual touch, for which he blessed the name of Harry Furniss and those long hours in Blairlogie, where he had sketched everybody and everything, alive and dead. Once he had seen a man or woman, he could produce a useful likeness, and he was not deceived by disguises. Few people have any aptitude for disguise; they put too much faith in dyed hair, changes of clothes, and peculiar walks; they disguise their fronts, but they neglect to disguise their backs, and Francis, who had learned the lesson from Saraceni, could identify a back when he might be puzzled by a face. So he amused himself by decorating his reports with sketches that were doubtless more useful than he knew, because Uncle Jack was not communicative, and never praised. He was not permitted to use a typewriter, because the sound, late at night, might rouse the suspicion of a landlady; his reports, written in an exquisite, tiny Italic hand, and ornamented with sketches, were little works of art. But Uncle Jack seemed impervious to art, and filed them without comment on their appearance.

What was drudgery for the first months of the war became dangerous misery after the coming of the air raids on London, by day and night in the autumn of 1940, and by night until May of 1941. It was in the great fire-raid of December 29 that Francis lost what had become his chief treasure.

He had rediscovered Ruth Nibsmith, meeting her by chance one October night in a Lyons restaurant where he had gone for a meal before taking up one of his long vigils across the street from a suspected house.

“Le Beau Ténébreux! What a piece of luck! What are you up to? Not that I need to ask; you look the complete snoop. Who are you snooping on?”

“What do you mean, I look a snoop?”

“Oh, my dear—the stained felt hat, the seedy raincoat, the bulge in the pocket where the notebook is kept—of course you’re a snoop.”

“You only say that because you’re a psychic. My disguise is impenetrable. I am The Unknown Civilian, who is catching it so hard these bad days.”

“Not half so hard as he’ll be catching it before the end of the year—speaking as a psychic.”

“You’re right, of course. I am doing confidential work. What are you doing?”

“Also confidential.” But after some chat it came out that Ruth was in Government Code and Cipher. “Of course, I have the puzzle-solving sort of mind,” she said; “I think it was my ability to do the Times crossword in half an hour that got me the job. But being a psychic does no harm, either. And that’s enough of that.” She glanced up at the poster on the wall, which was a picture by Fougasse of Hitler with an enormous ear cocked, and the legend “Careless Talk Costs Lives”.

They renewed their friendship, so far as Francis’s peculiar assignments and Ruth’s occasional night duties allowed, and this meant renewal of their happy hours in bed. Ruth lived in a very small flat in Mecklenburgh Street where the landlady was either indulgent or indifferent and perhaps once a week they contrived a happy hour or so. In wartime London, which had become so grey and stuffy, where laundry was a difficulty and baths were uncertain because of broken water-pipes, it was bliss to strip off their clothes and tumble into the not very clean sheets and lose themselves in a communion where no rules of security had to be remembered and tenderness and kindness were all that mattered. Perhaps it was odd that they never talked of love, or exchanged promises of fidelity; but they felt no need of such words. Without ever saying so, they knew that time was short and the present everything, and a union achieved when chance permitted was a treasure snatched from destruction.

“If a bomb were to blow us up now,” said Francis, one night when they had disobeyed the sirens and stayed in the warm bed when they ought to have gone to the nearest chilly shelter, “I would feel I had died at the peak of my life.”

“Don’t worry, Frank. No bomb is going to get you. Don’t you remember your horoscope at Düsterstein? Old age and fame for you, my darling.”

“And you?”

She kissed him. “That’s Classified Information,” she said. “I’m the decoder, not you.”

On the night of December 29, when the great fire-raid struck, Francis was on the job, watching a door through which nobody came or went, until it became impossible to keep at his post any longer, and he went to a Tube station, where he lay on the hard pavement with some hundreds of others, unsleeping and in terror. When at last the all-clear sounded he went as far toward Ruth’s flat as was possible, for fires were raging and whole streets of houses had disappeared.

She had been rescued, and in a shorter time than he had dared to hope he found her in a hospital. Rather, he found a body swathed in packs of saline solution, a body so heavily sedated that only one hand could be seen, and he sat for several hours, holding it, and praying as he had not prayed since childhood that by holding it he was being of some comfort. But the time came when the ward sister beckoned him away.

“No use now. She’s gone. Was she your wife? A friend?”

“A friend.”

“Do you want a cup of tea?” It was not much, but it was everything the hospital had to offer. Francis did not want a cup of tea.

So ended the greatest comfort he had ever known, which had lasted, he reckoned, a little less than ten weeks. Nothing during the forty-one years of life and a kind of distinction that remained to him brought anything to equal it.

A hero of romance might have undergone what is called, not very descriptively, a nervous breakdown, or might have thrown away his letter of exemption and pushed his way into the armed services, seeking death or revenge. Francis’s heroism was of another sort; he pulled about him a harsh cloak of stoicism, shut the door on love, and drudged on at his tedious work until Uncle Jack, perhaps sensing a great change in him, or finding new worth in him, promoted him to something a little more interesting. He next sat for several months in a small office in a building that did not in the least suggest MI5, and coordinated reports that had been brought in by watchers like himself, and tried to make sense of information that was usually uninformative. Only once, in all this time, did he have any certainty that he had been instrumental in uncovering an enemy agent.

It was not wholly loneliness and drudgery. Early in 1943 his father turned up, now revealed as MI5’s Security Liaison Officer for Canada, and rather a bigwig, for he stayed at Claridge’s and could have commanded a car for his use, if he had not preferred to walk. The Wooden Soldier was more wooden than ever, and his monocle was, if possible, more a part of his face than it had been before. He brought news of home.

“Grand’mère and Aunt Mary-Ben won’t be long with us, I’m afraid. They’re old, of course; the old lady is well over eighty, and Aunt is eighty-five if she’s a day. But it isn’t age that ails them; it’s parsimony and bad food. That miserable Doctor is even older, but he is remarkably bobbish and keeps the old girls ticking. I never liked him. The worst sort of Irishman. Your mother is well, and as beautiful as the first day I saw her, but she’s developing some odd tricks; faulty memory—that kind of thing. The surprise of the pack is your young brother Arthur. No university for him; he says you went to two and that’s enough for the family. He’s been deep in the business already, and very sharp. But he’s in the Air Force now; I expect he’ll do well.

“And you’re doing well, Jack Copplestone tells me.”

“I wish he’d tell me once in a while. I sometimes think he’s forgotten me.”

“Not Jack. But you’re not the easiest man to place, Frank. Not a swashbuckler, thank God. He’ll use you when the right thing turns up. Still, I’ll say a word to him. Not as though you had said anything to me, of course. But just to keep the wheels turning.
