"And suppose we leave it?" asked the professor, restraining his irritation as best he could. "What then?"

"Then I am afraid—ah—unpleasant consequences would result," was the bland answer. "Surely you realize that I could not let you and young Dr. Stoddard rejoin your expedition with this story to report."

They realized it quite well.

"But suppose we agree not to report it?" said Professor Prescott.

"Not to doubt your honesty of intention," replied Krassnov sharply. "I would refuse to accept such an agreement."

"Then I see nothing else but to decline your kind proposal," said Stoddard, before the professor could formulate further words. "What do you propose to do—murder us?"

"Nothing so personal," said the prince, with his sardonic smile. "I shall merely turn you over to my little subjects. They no doubt will deal with you as your merits warrant."

Whereupon he pressed a button under that elaborate teakwood table. The musical gong they had heard before sounded again, and the prince's two Cossack retainers reappeared.

He addressed them briefly in Russian, adding to his guests:

"Adieu, friends! If you change your minds, you have only to speak. You will be understood, and I shall be gratified."
