He switched on the machine, refilled their glasses with a pleasant Tawny Port, and sat down in his own chair. Then, for the next hour and a half, while he changed the tapes from time to time, they listened, almost without comment. The recordings all began with grunts, shouts, curses and protests, often followed by an unintelligible rigmarole, but then settled down into arguments during which two different voices were clearly perceptible -Otto's in English, as spontaneous and unaccented as though he had spoken no other tongue since his birth; Lothar's, also speaking fluent English, but with a faintly nasal twang. Otto's was almost always angry; Lothar's persuasive and sweetly reasonable, except for occasional outbursts in the later recordings when he resorted to violent threats.
At length the recordings were over, and Forsby mixed his guests and himself whiskies and sodas before they got down to discussing them.
Verney said: 'You are right, Dick, about Lothar giving the impression that he is fed up with Moscow. If one can believe what he says it seems that he hoped the Russians would launch a war against the N.A.T.O. Powers and establish a New Order, more or less on Nazi lines, in Western Europe and later in the United States. But he has come to the conclusion that the Kremlin is not prepared to play it that way and prefers a policy aimed at bringing the democracies to ruin by gradually gaining control of the whole of Asia and Africa and closing all the markets in them to the nations of the West.'
'To me, Lothar sounded like a megalomaniac,' Barney remarked. 'My guess is that personal power is what he is after. He wants to see some sort of drastic upheaval before he is too old to play a part in it.'
'I don't altogether agree,' Forsby countered. 'You may be right to the extent that he no longer sees eye to eye with his Russian masters because he thinks that he'll be dead before their policy of peaceful penetration begins to pay really big dividends but to me his aim seems to be to bring about a completely new world order. When I was in Spain during the Civil War there, I talked with quite a number of anarchists, and some of the things he says tally with the views they expressed. It's a topsy-turvy sort of doctrine based on the old idea that out of evil cometh good. They want to destroy all forms of government and start again from scratch.'
'He is a destroyer, all right,' said C.B. grimly. 'But I think we must regard all this 'good of mankind- brotherhood of nations' stuff as eye-wash. Whatever he may say, there's not much question about his being a Soviet agent.'
'I suppose so,' Forsby agreed, a shade doubtfully. 'Although, in one passage, he did say that having left Russia he did not mean ever to go back there.'
'Come, come, Dick. If he is not a secret agent, what reason could he have for wanting to get hold of this fuel formula? And if he is a secret agent, knowing his background as we do, what country would he be working for other than Russia?'
'It's a hundred to one you're right, Sir,' Barney put in. 'But, as he is a scientist and worked first in the States, then in Germany, then in Russia, there is just a possibility that he's got some box of tricks of his own and wants our fuel to try it out with-a flying saucer, or something.'
'You're off the mark there, young feller. Such formulae are extraordinarily complicated things, and no private person could get one of them made up.'
Forsby shook his head. 'I don't agree with you there, C.B. The ingredients are all procurable from any big manufacturer of chemicals. The only secret is in the combination and proportions. It would be expensive, of course; but I'm pretty sure he could get the job done without being brought to book for having illegal possession of the formula in any of several countries outside the N.A.T.O. group - Sweden, Switzerland or Spain, for example. And if he has the money, there would be nothing to stop him from having built to his own designs some revolutionary type of aircraft as Sullivan suggests.
Verney offered round his case of long cigarettes, took one himself, and said: 'Maybe you're right; but we're wasting our time with these academical speculations. Let's get back to earth. Whatever Lothar's future intentions may be, he is endeavouring to secure a top-secret document, and coming here tomorrow to receive it from his brother. As their arrangements have all been made by telepathic communication, we have not got a scrap of evidence against either of them. The tape recordings would justify our holding Otto in preventative arrest, but what a man says in his nightmares cuts no ice in a court of law, except in support of something much more definite. So unless the document is actually handed over, Lothar will be able to cock a snook at us, walk off, and plan a further attempt to get hold of it which we may not be fortunate enough to find out about. As against that, if we do let Otto hand it over and Lothar manages to get away with it, quite apart from having let down our side, it will be bowler hats for all of us. Now, any suggestions?'
Barney held up his hand. 'Yes, Sir. Otto has had a lousy deal all through. He's resisted Lothar's demands until he has been driven off his chump, and he seems a very decent sort of chap. If you let the show go on you'll have to pinch him as well as Lothar and, whatever we may say afterwards about extenuating
circumstances, he'll have committed a treasonable act, so he'll get a prison sentence. That strikes me as damnably unfair.'
'I agree,' Verney nodded, 'and I couldn't be sorrier for the poor devil. But, if we are to get the goods on Lothar, I see no way of letting Otto out. Still, if you've had a brainwave, let's hear it.'
'It is that you should see Otto tomorrow morning, tell him we know what is going on and offer him the chance both to keep in the clear himself and get his own back on his brother. If he agreed to play, instead of taking the real formula to the meeting he would hand over a dud one. If Lothar gets away, there would be no harm done; but, if we catch him, you'll have a clear case to put him away for a good long stretch.'
C.B. shook his head. 'You are forgetting the psychic angle. Lothar checked up on Otto last night. That's how he learnt that the meeting they had arranged for today was off. He may check up again tonight and again tomorrow, to make certain that Otto isn't slipping and likely to let him down at the last moment. How far he can see into Otto's mind, we don't know. It's not far enough, thank God, to register scientific experiments or he wouldn't need to go to so much trouble to secure a written formula; but he must be highly sensitive to Otto's vibrations. If he sensed a change of mind, suggesting that Otto was helping to lay a trap for him, he would not turn up and, if we miss this chance to catch him, we may never get another.'
'All the same,' said Forsby, 'I agree with Sullivan that we ought to try to think of some way to protect Otto from himself.'
'I only wish we could, Dick. But wait!' C.B. suddenly sat forward and put his first finger alongside his big nose. 'I believe I've got it, boys. Why shouldn't we detain Otto just before he's due to leave the Station, borrow the old raincoat and beret that Otto has been told to use as signs of his identity, dress up in them whichever of the Air Force police we have selected earlier as having a figure most like his, and send this chap to the rendezvous with a dud formula?'
The other two considered his suggestion for a moment, then Forsby objected. 'When Lothar got near enough to
