'You are well informed, my young friend,' Ossendorf admitted quietly.

'It has been suggested,' Lavendale said, speaking slowly and looking Ossendorf in the face, 'that you should change the wireless operator on all those vessels for a person approved by the British Government.'

There was a moment's deep silence. Mr. Weald had paused with his knife already pressed against the last string of the bottle. Jenkins was standing with his mouth open, a little dazed. Ossendorf shrank back as though he had received a blow. It was obvious that he retained his composure with an effort.

'What do you mean?' he demanded.

'Simply this,' Lavendale replied firmly. 'Already the Iris and the Southern Star, with enough ammunition on board to have supplied an army, have gone to the bottom. I mean, sir, that every one of those remaining nine boats on which is to be packed the whole production of the greatest ammunition plant in America, is doomed to go to the bottom.'

Two great drops of sweat had broken out on Ossendorf's forehead. His face seemed suddenly to have grown thinner. His mouth was open. He glared at Lavendale, but he was utterly incapable of speech. The latter turned to Weald.

'Mr. Weald,' he said, 'this contract for your entire output can be signed within twenty-four hours, either by a representative of Russia other than Baron Ossendorf, or by the secretary of the British Munition Board. This man Ossendorf is a paid traitor—the Judas of the war.'

Mr. Weald was incapable of coherent speech.

'You mean,' Jenkins faltered, 'that he is in the pay of Germany?'

'Ask him!' Lavendale suggested scornfully.
