"Johann Schmidt!" replied the other, with some little astonishment. "Who the devil is he? I don't know that I ever heard of him."

It was Browne's turn this time to feel surprised. "I asked because I understood that he was going to send some one to me this evening."

"That is very possible," MacAndrew answered; "but let me make it clear to you that I know nothing whatsoever of him; in matters like this, Mr. Browne, you will find it best to know nothing of anybody."

After this plain speech, Browne thought he had grasped the situation. "We will presume, then, that you know nothing of our friend Johann," he said. "Perhaps you have a plan worked out, and can tell me exactly what I ought to do to effect the object I have in view."

"It is for that reason that I am here," resumed MacAndrew, with business-like celerity, as he flicked the ash from his cigarette. "I've got the plan fixed up, and I think I can tell you exactly how the matter in question is going to be arranged. To begin with, I may as well inform you that it is going to be an expensive business."

"Expense is no difficulty to me," replied Browne. "I am, of course, quite prepared to pay a large sum, provided it is in reason, and I am assured in my own mind, that the work will be carried out in a proper manner. How much do you think it will cost me?"

"Five thousand pounds in good, solid English gold," answered MacAndrew; "and what is more, the money must be paid down before I put my hand to the job."

"Five thousand pounds in good, solid English gold."
