He walked back and forth, muttering to himself still keeping his eye on Grace for fear that she might escape.

"Oh, what shall I do?" thought the terrified girl. "Goodness knows what he'll think of next. He may keep me here until dark, and I shall die if I have to stay here until then, I must get away."

Grace knew that it would be sheer folly to try to run. Her captor would overtake her before she had gone six yards, not to mention the fit of rage her attempted flight would be likely to throw him into.

She anxiously scanned the neighboring fields in the hope of seeing old Jean, the hunter. He was usually not far away. But look as she might, she could discover no sign of him. There was only one thing in her favor. It would be light for some time yet. Being June, the darkness would not descend for two hours. She must escape, but how was she to do it!

She racked her brain for some means of deliverance, but received no inspiration. Again she drew out her watch. Then her eye rested for a second on the little key that hung on her watch chain. It was the key to the lean-to in which David kept his aëroplane. Like a flash the way was revealed to her. But would she be able to carry out the daring design that had sprung into her mind? She would try, at any rate. With an unconcern that she was far from feeling, Grace walked carelessly toward the door of the lean-to.

The demented man was beside her in a twinkling He clutched Grace by the arm with a force that made her catch her breath.

"What are you trying to do!" he exclaimed, glaring at her savagely. "Didn't I tell you that you couldn't go away!"

He held her at arm's length with one hand, and threateningly shook his finger at her.

"Remember, once and for all, that I am your emperor and must be obeyed. Disregard my commands and you shall pay the penalty with your life. What is the life of one like you to me, when I hold the fate of nations in my hands? Perhaps it would be better to put an end to you now. Women are ever given over to intriguing and deception. You might betray me to my enemies. Yet, I believed you loyal in the past. I——"

"Indeed I have always been loyal, my emperor," interrupted Grace eagerly. "How can you doubt me?"
