"Yes, Ivan Saranoff. He was here on this marsh to-night. There were four of his men and we got two, letting the most important one get away."
"You've got four, Dr. Bird," said a guttural voice from the dark.
Dr. Bird whirled around and shot out the beam of his light. A third Russian was revealed in its gleam.
"Hands up!" cried the doctor.
"I'm willing to be captured, Doctor," said the Russian. "Your search for Saranoff is useless. He has been gone for an hour. He is not one to risk his own skin when others will risk theirs for him. He fled after he left the cave."
"Do you know where he has gone?"
"I wish I did, Doctor. If I knew, we'd soon have him, I hope."
The Russian's voice had changed entirely. Gone were the heavy guttural tones. In their place was a rich, rather throaty contralto. Carnes gave a cry of astonishment and turned his light on the prisoner.
"Thelma!" he gasped.
