"I do not as a rule suffer from over-confidence, sir," he said, "but I think I can promise you that by Wednesday night not only will the papers be in our hands, but Mr. Jocelyn Thew will be so disposed of that he will be no longer an object of anxiety to us."

"Get on with the good work, then," was Mr. Brown's laconic farewell.

Late on the following afternoon, Jocelyn Thew and Gant paced the long platform at Euston, by the side of which the special for the American boat was already drawn up. Curiously enough, in their immediate vicinity Mr. Brightman was also seeing a friend off, and on the outskirts of the little throng Mr. Henshaw was taking an intelligent interest in the scene.

"Perhaps, after all," Jocelyn Thew declared, "you are right to go. You have been very useful, and you have, without a doubt, earned your thousand pounds."

"It was easy money," the other admitted, "but even now I am nervous. I shall be glad to be back once more in my own country."

"You are certainly right to go," the other repeated. "If you had been different, if you had been one of those men after my own heart," Jocelyn Thew went on, resting his hand for a moment upon Gant's shoulder, "one of those who, apart from thought of gain or hope of profit, love adventure for its own sake, I should have begged you to stay with me. I would have sent you on bogus errands to mysterious places. I would have twisted the brains of those who have fastened upon us in a hundred different fashions. But alas, my friend, you are not like that!"

"I am not," Gant admitted, gruffly but heartily. "I have done a job for you, and you have paid me very well. I am glad to have done it, because I love Germany and I do not love England. Apart from that my work is finished. I like to go home. I am happiest with my wife and family."

"Quite so," his companion agreed. "I know your type, Gant,—in fact, I chose you because of it. You like, as you say, to do your job and finish with it,—and you have finished."

The doctor turned for a moment deliberately round and looked at his companion. He was a heavy-browed, unimaginative, quiet-living man. The things which passed before his eyes counted with him, and little else. The thousand pounds which he was taking home was more than he had been able to save throughout his life. To him it represented immense things. He would probably not spend a dollar more, or indulge in a single luxury, yet the money was there in the background, a warm, comforting thing.

"You have still," he said, "a desperate part to play. Can you tell me honestly that you enjoy it, that you have no fear?"
