"Please go on," he said.

The girl smiled. "I am afraid you are an awful gossip," she rallied, but became more serious. "I don't like him very much, but uncle says that is my prejudice. He is one of those quiet, sure men who say very little and make one feel rather foolish. Don't you know that feeling? It is as though one were dancing the tango in front of the Sphinx."

Poltavo showed his white teeth in a smile.

"I have yet to have that experience," he said.

She nodded.

"One of these days you will meet Dr. Fall and you will know how helpless one can feel in his presence."

A remarkable prophecy which was recalled by Poltavo at a moment when he was powerless to profit by the warning.

"Mr. Gorth?"

Again she hesitated and shrugged her shoulders.
