Prince Zuvor appeared.

“This is a pleasure,” exclaimed the prince, in a tone of welcome. “I had not expected you to accept my invitation.”

Lamont Cranston rose leisurely, and grasped Prince Zuvor’s hand.

“You did not expect me?” he asked.

“I did not,” replied the prince. “You recall, of course, the dangers that I mentioned. I had supposed that you would rely on your better judgment, after you had considered the matter.

“This house is watched. Those thick curtains are evidence of that fact. They are not merely ornaments.”

Lamont Cranston shrugged his shoulders.

“The danger does not worry me,” he said. “I would even welcome a bit of danger. My life is one of leisure. It grows monotonous at times.”

Prince Zuvor looked toward the large dog that was standing by Cranston. He snapped his fingers as a command for the wolfhound to retire to the corner. Then his gaze became fixed upon the floor, and Cranston detected a look of surprise upon his face.

“What is it?” asked the millionaire.
