Dimly, for all the windows of the room were closed, she heard a car come up and stop before the house. It aroused her from the curious condition of lethargy into which she was falling. She turned her head sharply aside, the physical reflection of a mental effort to remove her gaze from the long, magnetic eyes of Ormuz Khan. And:

“Do you think that is Mr. Harley?” she asked, and failed to recognize her own voice.

“Possibly,” returned the Persian, speaking very gently.

With one ivory hand he touched his knee for a moment, the only expression of disappointment which he allowed himself.

“May I ask you to go and enquire?” continued Phil, now wholly mistress of herself again. “I am wondering, too, what can have become of Mrs. McMurdoch.”

“I will find out,” said Ormuz Khan.

He rose, his every movement possessing a sort of feline grace. He bowed and walked out of the room. Phil Abingdon heard in the distance the motor restarted and the car being driven away from Hillside. She stood up restlessly.

Beneath the calm of the Persian’s manner she had detected the presence of dangerous fires. The silence of the house oppressed her. She was not actually frightened yet, but intuitively she knew that all was not well. Then came a new sound arousing active fear at last.

Someone was rapping upon one of the long, masked windows! Phil Abingdon started back with a smothered exclamation.

“Quick!” came a high, cool voice, “open this window. You are in danger.”
