'If Colonel Washington's confession to having witnessed the murder of my husband is not sufficient to arrest him on, some pretext for removing him from his command should be found at once; because he may endanger peace. He says his flying career may soon be brought to an end by the introduction of rockets, and I believe he is planning to start a new career by going over to the Russians. He says that Russia will never attack the U.S., but the U.S. may be driven by economic reasons to attack Russia. He thinks that given peace Russia will be able to wreck the commerce of the West and so dominate the world in ten years time. Therefore she would lay down the red carpet for anyone who could bring about the abolition of all nuclear weapons. A way to do this would be to drop an H bomb on Switzerland. Neither side would take action while trying to find out who dropped the bomb. Meanwhile, eyewitness reports of the horrors caused would lead to the democratic Governments of the West being forced by their people to agree a pact with the Soviet Government to scrap all nuclear weapons. The Russians could then go ahead without fear with their programme of underselling the West in the world's markets and conquest by peaceful penetration. Colonel Washington could fly one of his big aircraft out at any time, drop an H bomb on Switzerland, and fly on to reap a great reward in Russia. It is imperative that he should be deprived of the power to do so. Mary Morden for Colonel Verney, care of Scotland Yard.'

Dramatically the whispering ceased and the tape came to an end. For a moment the four men standing round the machine remained white-faced and silent. Then C.B. looked across at Otto and said,

'You were right. They are in Switzerland. But why, instead of taking one of his bombers and dropping the bomb, did Washington take only the war-head for use with the rocket?'

'Because in the Satanic hierarchy Lothar is his boss, and Lothar wanted it that way,' replied the scientist.

'But why?' Verney asked again.

'Only one answer to that,' snapped Richter. 'Lothar doesn't mean the big bang to take place in Switzerland. He has just kidded Washington along about that. He means to launch his rocket so that it hits some place else; and that could start a world war.'
