“And yet there’s one person quite near at hand who in all probability knows where he is, or at all events where he is likely to be.”

“Who is that?” asked Tuppence, puzzled.

“ Mrs. Vandemeyer.”

“Yes, but she’d never tell us.”

“Ah, that is where I come in. I think it quite likely that I shall be able to make Mrs. Vandemeyer tell me what I want to know.”

“How?” demanded Tuppence, opening her eyes very wide.

“Oh, just by asking her questions,” replied Sir James easily. “That’s the way we do it, you know.”

He tapped with his finger on the table, and Tuppence felt again the intense power that radiated from the man.

“And if she won’t tell?” asked Julius suddenly.

“I think she will. I have one or two powerful levers. Still, in that unlikely event, there is always the possibility of bribery.”

“Sure. And that’s where I come in!” cried Julius, bringing his fist down on the table with a bang. “You can count on me, if necessary, for one million dollars. Yes, sir, one million dollars!”

Sir James sat down and subjected Julius to a long scrutiny.

“ Mr. Hersheimmer,” he said at last, “that is a very large sum.”

“I guess it’ll have to be. These aren’t the kind of folk to offer sixpence to.”

“At the present rate of exchange it amounts to considerably over two hundred and fifty thousand pounds.”
