"Please don't go," Olga implored.

"I can hardly remain under the circumstances," he said.

He knew that to further his design Karl and Olga should meet quite alone. He would see to it that even old Heinrich did not interrupt them until Olga had repeated her confession of love, and the hoax of the letter had been revealed. Then he would reappear, with the letter, and they might read it together.

Olga knew that her own frail, feminine heart would give way if she were left alone to meet Karl. Evil as she believed Millar to be, yet she dreaded his going now.

"I am afraid to be alone with him," she said. "Won't you please stay?"

"But if I stay, how could you speak to Karl about the letter?" Millar asked. "And you must say something about it, you know. I would only be in the way."

Olga weakened and began to pace the floor again.

"Well, I shall be quite frank with him," she said. "I shall be honest. I shall ask him for the last time——"

Karl's voice was heard in his own room, calling to Heinrich.

"He is coming," Millar said. "I will leave you."
