That presented no difficulties whatever. Upjelly was speaking to someone, obviously an inferior, who replied, "Yes, sir," or, "Certainly, I have already done it."

Then Jones cut in, and here again I noticed an entire change in the quality of the man's voice. It was not Jones speaking now, it was the renowned Kiderlen-Waechter, of whom my brother had spoken three nights ago, or I would have eaten my hat. There was no mistaking the keen, arrogant note of command. The bland Mr. Jones never spoke like that, though the voice was the same. Then I distinctly heard the sound of a door either being shut or sliding in its grooves. There was the splutter of a match, the sound of a gurgling syphon, and, to my intense relief, Doctor Upjelly and his unseen companion began to speak in English.

"No, it's impossible. I have, in my safe at the school, all the plans. Our secret service on this coast has been working untiringly. For three days at least, after to-morrow night, the plans will hold good. In them is the station of every patrolling ship, full maps of this part of the coast, the disposition of forces—everything necessary for the Admiral. The tide to-morrow night will be even higher than it is now. The moon is waning; weather conditions point to a dark, tempestuous night to-morrow. She will come and take you away with the plans."

"Which I shall deliver to the Admiral within twenty-four hours, for the rendezvous is arranged, and I shall meet him in the middle of the North Sea."

"I shall be sorry to lose you, Admiral Kiderlen-Waechter."

"It will only be for a time. I shall soon return—as you know."

There was a sound of laughter, low, guttural, and strong.

"And what will you do, von Vedal?"

"To-morrow night I shall be with you, as you know, and see you go. Then I shall take my stepdaughter to London, to the house you know of, where I shall await you. The issue will not be long and you can claim your reward. I shall leave the school, ostensibly for a day or two, but it will never see me again, as you can understand. Fritz has put that meddling Commander Carey hors de combat—the arrow was a clever idea and no one suspects. As a matter of fact, I don't suppose for a moment that his visit was anything but just what it appeared to be—for purposes of rest and a little sport and to see his brother. Gott im Himmel, what fools these people are! Now, take for example that brawny young donkey, Mr. John Carey, my assistant-master. He fancies himself in love with my elder stepdaughter, Doris."

"And he may well be so, for she is a beautiful and charming young lady. Would I not do anything in the world for her sister?"
