The room was suddenly filled with a greenish light, as if someone had just taken a flash-light photograph. Underhill was thrown violently back into his chair, and the ball crashed down on the table, splitting it from end to end.

Without moving a muscle of his face, and taking no notice of the gestures of pain made by Underhill as he sat rubbing his arm and shoulder, Edestone resumed:

“Mr. Underhill, I will not take any more of your valuable time to show you my drawings and photographs, but I beg you to say to Sir Egbert Graves that you do not think with Lord Rockstone that the American Secretary of State has been deceived, and that you hope he will, when he sees me tomorrow, try to forget for a while that he is an Englishman and be a little bit human. You know, Underhill, confidence and pigheadedness are not even connected by marriage; much less are they blood relations. By Jove,” he grinned, “you can tell him I’ll stick him up against the ceiling if he insists upon handling me with the ice tongs and leave him there until you take him down; that is, if you care to take another little shock.”

Underhill, although he might have thought at another time that it was his duty to resent such light and frivolous reference to the heads of His Majesty’s Government, was now, however, occupied with more serious reflections, and overlooked the offence.

“I am sure,” he said, rousing himself, “that if Sir Egbert is convinced that you are working for the sake of humanity he will be most happy to make use of your talents.”

“That is exactly what I want him to do,” returned Edestone, “but not in the way in which you mean. I wish to be given authority to open negotiations for peace with the Emperor of Germany. Now, Mr. Underhill, do we understand one another?”

He rose to leave with this, but Underhill, stepping quickly forward, laid a hand upon his arm.

“You don’t suppose for a moment, Mr. Edestone, that we will allow you to leave England and go to Germany to sell them your invention and have it used against us?”

“You have my word, Mr. Underhill, and that of the American Secretary of State, that it is not my intention to sell to any government. With that assurance, unless your Ministry wishes to risk the chances of war with the United States, I think it will allow me to leave England and go anywhere I please. Good-morning, Mr. Underhill. I am sorry to have taken up so much of your valuable time, even more sorry to have broken His Majesty’s beautiful old oak table.”
