Apart from anything else, I said, I have certain rights. Conjugal rights. I demand their restoration. You filthy pig, she shouted; I've never had such filth spoken to me before. Get out of here at once. And then she gave me a very foul mouthful of German. And then she said: If you want a woman there are thousands in London willing to do it for the money. Some of them even walk the streets with little dogs, which is against the law. But do not come to me, no, not to me, do not come to me. I felt very bitter and ill-used then, but I could not really turn against her. Also I felt triumphant, because I would have her that night and she would not know it. But I boiled also within to think that this was my wife and other men could possess her and I could not. I became very cold and cunning outside, despite the boiling inside, and, when I saw her handbag lying open on the settee, I said: Give me a drink and then I'll go. A cold drink. Perhaps you have beer in the fridge. We always used to have it in the old days. All right, she said, go and help yourself. Then get out. But I said: For old time's sake, Brigitte, get me a drink with your own hands. Please. I ask no more. She shrugged and said: Oh all right, then went to get it. I knew that her key was in that bag. It was no trouble to get it out and put it in my pocket. When she brought the beer I drank it off in one draught. She said: You drink like a pig, just as you ate like a pig. I only smiled and said: A goodnight kiss? For old time's sake? But she wouldn't give me even that, my right. I left then and said: Goodbye, dear Brigitte. Look after yourself. She seemed a little puzzled to see me go without further trouble. Out in the street I looked up at her sitting-room window till the lights went out. Then I went home. Lucy was waiting for me with some nice hot supper.

I now had something to do every night. What I did mostly at first was to walk that street, seeing who went into her flat. Her trade was a high-class one, to judge by the cars that parked there. Once a policeman looked at me suspiciously but I got in right away with: Never mind, constable. This is a job. Private detective agency. He didn't ask to see my card or anything. The pleasure I got from watching was what, I suppose, is called a masochistic one. I never thought such pleasure was possible, but it is. It is not just what Shakespeare calls wearing the horns; it is making a kind of crown of horns.* I delayed my entering for as long as possible, letting weeks go by. I felt especially virtuous about submitting to all this delicious pain, since I'd told Lucy that I was after evidence for a divorce. When I got back at night she said: You poor dear. Let's have a nice hot drink before we go to bed.

I watched and watched till one night a very unpretentious car came to her door and a man got out of the car looking furtive. He darted up the stairs to the open doorway of the little block of flats and, in the light from the hall, I saw his profile fairly clearly. I knew I'd seen that face somewhere, but I couldn't think where. It seemed to me to be a fairly important face, but whether political or artistic or even in the ecclesiastical field I knew not. A Television Personality perhaps? That got closer to it. I felt I'd seen that face earnestly talking one night on television when Lucy and I were taking hot soup from our knees, I mean from bowls on our knees, with crackling slices of 1 Oh no, Roper. No no NO.

Ryvita. The face, I thought, was both political and televisual-something to do with a party political broadcast? I had to wait about an hour and a half before he came out, stuffing his wallet into his inside pocket, still looking furtive but more smugly furtive. It was about the time when the theatres were finishing, and there were one or two taxis coming down the street to turn on to Baker Street. This man hadn't yet got into his car, but I stopped a taxi and the driver said: Where to, guv? (or it may have been: Where to, mate?) I felt like giggling as I said: Follow that car once it starts. The driver said: I can't very well bleeding follow it while it's stationary, can I? Then he said: You mean it, guv (or mate)? Cor, this comes from seeing too much telly. But he did what I said.

It was a bit difficult, because other cars and taxis got in the way, but eventually we came to the area round about Marble Arch, and this car stopped outside what looked like a block of flats. The taxi-driver drew up very discreetly on the opposite side of the road. Now, he said, go in and get your man. Not too much rough stuff, mind. I paid him and he went off. I waited a little while then I went to the entrance where I'd seen the man go in. There was, as I'd expected, a sort of porter on duty in the entrance-hall. I said: Excuse me, but wasn't that Mr Barnaby who went in just then? He looked at me most suspiciously and said: What's it to you who went in, mate? (Too much of this mate, everywhere – the parody of friendliness of an uneasily egalitarian state.1) I said: Don't call me mate. My name is Doctor Roper. Sorry, he said, doctor. No, that wasn't no Barny, or whatever you said. That was none other than Mr Cornpit-Ferrers.2 And a very nice gentleman too. This porter went on then about his eloquence on television and (though how did he know, obviously no 1 From what pretentious TV play did you pick that up?

man for the Strangers' Gallery?) in the House. Also his generosity, always ready with the odd half-bar for small services rendered. Like now, going to put his wife's car away for the night, that being it as he'd just come in, him perhaps not wanting to use the regular Bentley this evening. I donated 10s or half-a-bar and said: Married then, is he? He said: Thank you, sir, doctor. Yes, a lovely wife and three kids, lovely kids.

Adulterous whoring swine. But at last I saw a way of getting Brigitte back. Next time I would Confront Them both, as that time with that ghastly Wurzel. But no, I'd played no man's role then; I'd had to leave it to Hillier. I watched and waited another week and he didn't come, the House perhaps sitting late. But one evening a man for all the world like that filthy West German Devil came, dropped by somebody in a car. He shouted something like Guter Kerl, very foolishly, to the driver, who shouted back some-think like Sei gut before going off. This time I decided to go up, after a decent, wrong word there, interval. I was blazing, that bad time, the first speck of rot in the apple, coming back to me. Outside her door I had to pause and take deep though silent breaths. Then I heard them talking very serious German inside. This made me wonder. Surely there should be none of that going on, the seriousness reserved to a different kind of communication. I listened and I kept hearing the name Eberswalde. Eberswalde? That was in East Germany. Brigitte had spoken a couple of times about some filthy relative she hated who lived in Eberswalde. I listened hard but could take in little. I could not take in very fast German, despite my marriage to one who spoke it when in passion or anger. At one point Brigitte seemed to start to cry very gently. Was this relative in Eberswalde really so filthy? Had other relatives turned up there, not filthy at all? The only other word that came clearly through the door was another name – Maria. I heard it often. Surely Brigitte had spoken of a niece of that name, someone who was, apparently, far from filthy. And then, quite loud, Brigitte cried: But I know nothing, not yet. Softer, the man seemed to say: But you will know. You will know much if you try harder. And then: Ich gehe. I got away quickly before he left and walked right down the street, as far from the flat as possible.

What did all this mean? I couldn't tell. It might mean nothing. But, like everybody else, I'd had this security thing hammered into me, and I couldn't help thinking that a German prostitute (terrible thing to call Brigitte) who had relatives in East Germany would, in free and easy London, be all too much a subject for proposals or target for threats from the Other Side. Not that I could take it very seriously. We scientists who were socialists were working out a highminded blueprint about International Cooperation in Research, and we saw, rightly, all research as one – all answers to all questions free to all. War was to be outlawed, and we were in the vanguard of the outlawing process, the scientist having great responsibilities and terrible powers.
