The Russian was not unmoved. But his agitation was quickly suppressed. He forced Ralph down in his seat again.

"You will have to behave better than that if you are to be a trusty ally of mine," he said. "Come, that is better! Sit still; she is coming this way."

"I'm all right now," Ralph replied. "The shock of finding myself in the presence of Princess Zara was overpowering. Have no fear for me."

A tall woman, magnificently dressed, was making her way towards Tchigorsky. Her face was the hue of old ivory, and as fine; her great lustrous eyes gleamed brightly; a mass of hair was piled high on a daintily poised head. The woman might have been extremely young so far as the touch of time was concerned, but the easy self-possession told another tale.

The red lips tightened for an instant, a strange gleam came into the dark magnetic eyes as they fell upon Tchigorsky. Then the Indian Princess advanced with a smile, and held out her hand to the Russian.

"So you are still here!" she said.

There was the suggestion of a challenge in her tones. Her eyes met those of Tchigorsky as the eyes of two swordsmen might meet. There was a tigerish playfulness underlying the words, a call-note of significant warning.

"I still take the liberty of existing," said Tchigorsky.

"You are a brave man, doctor. Your friend here?"
