“Really, Mr. Jacks,” he began,—

“I hope, sir,” the Inspector protested, “that you will not think I am asking this question through any irrelevant curiosity. I am beginning to form a theory of my own as to these two murders, but it needs building up. The offering of a reward like this, if it emanates from the source which I suspect that it does, gives a solid foundation to my theories. I am here, sir, in the interests of justice only, and I should be exceedingly obliged to you if you would tell me whether the suggestion of this large reward did not come from the Foreign Office?”

The Minister considered for several moments, and then slowly inclined his head.

“Mr. Jacks,” he said, “your question appears to me to be a pertinent one. I see not the slightest reason to conceal from you the fact that your surmise is perfectly accurate.”

A flash of satisfaction illuminated for a moment the detective’s inexpressive features. He rose and took up his hat.

“I am very much obliged to you, sir,” he said. “The information which you have given me is extremely valuable.”

“I am glad to hear you say so,” the Home Secretary declared. “You understand, of course, that it is within the province of my department to assist at all times and in any possible way the course of justice. Is there anything more I can do for you?”

Inspector Jacks hesitated.

“If you would not think it a liberty, sir,” he said, “I should be very glad indeed if you would give me a note which would insure me an interview with Sir Edward Bransome.”

“I will give it you with pleasure,” the Secretary answered, “although I imagine that he would be quite willing to see you on your own request.”
