'Nothing. It is simply that his colleagues are worried about his mental state. They all have their own quarters, of course, but the unattached ones feed and spend a good part of their leisure hours in a mess. For some weeks past Khune's behaviour there, particularly when it is getting late at night, has puzzled the others. They say that for short periods he talks and behaves as though he were an entirely different person. Did you happen to read that book The Three Faces of Eve?'

C B. shook his head. 'No, but I heard several people talk about it. I gather it was a report by two professional psychiatrists on an American woman who suffered from split personality.'

'That's right. I found it absolutely fascinating. Normally she was a prudish, dowdy little housewife with a shy, retiring nature, but at times she changed into a gay, bawdy-minded, come-hither girl, bought herself expensive clothes, made herself up fit to kill and went out to hit up the night spots. Then a third individuality emerged when she appeared to be a grave, sensible, responsible woman. And these changes in personality took place not once, but many times actually under the eyes of the men who were examining her; so one can hardly write the whole thing off as a hoax.'

'No, schizophrenia is a mental state now fully accepted by the medical profession. If that's the trouble with this chap Khune, I take it your worry is that while dominated by this new personality ho may commit some breach of security?'

'Exactly. When in his normal state we have every reason to believe him to be a patriotic naturalized Briton, but when he has these queer fits he appears to be anything but that. The sort of thing he says is that the only hope for the world is a new deal, starting with the elimination of all the old Imperialist and Capitalist governments; that the United States' oil interests and big business are at the bottom of all the ills that are afflicting mankind, and that true freedom for the individual can only be achieved by complete equality for all.'

'That sounds like the old Communist gags. Do you think he is being got at by the Russians?'

'Maybe, but somehow I don't think it's that. His ideas seem to be more on the old anarchist lines—the complete abolition of all rule with everyone muddling along in little share-and-share alike communities. Anyhow, as he was away this weekend, I decided, on the off-chance that he is in communication with some no-goods and that I might find something that would throw light on the matter, to search his quarters.' Forsby opened his brief-case and taking from it a typescript, added: 'There was nothing of any interest among his correspondence, but in his desk I found a document in his writing, and this is a copy that I took of it.'
