In this contemplation he grew restful; his thoughts ceased feverishly to race along that one hateful groove; the bright star seemed to soothe him. As a result of his fixed gazing, it now appeared to have increased in size. This was a common optical delusion, upon which he scarcely speculated at all. He recognised the welcome approach of sleep, and deliberately concentrated his mind upon the globe of light.

Yes, a globe of light indeed—for now it had assumed the dimensions of a lesser moon; and it seemed to rest in the space between the open windows. Then, he thought that it crept still nearer. The realities—the bed, the mosquito curtain, the room—were fading, and grateful slumber approached, and weighed upon his eyes in the form of that dazzling globe. The feeling of contentment was the last impression which he had, ere, with the bright star seemingly suspended just beyond the netting, he slept.


CHAPTER XV

THE WITCH-QUEEN

A man mentally over-tired sleeps either dreamlessly, or dreams with a vividness greater than that characterising the dreams of normal slumber. Dr. Cairn dreamt a vivid dream.

He dreamt that he was awakened by the sound of a gentle rapping. Opening his eyes, he peered through the cloudy netting. He started up, and wrenched back the curtain. The rapping was repeated; and peering again across the room, he very distinctly perceived a figure upon the balcony by the open window. It was that of a woman who wore the black silk dress and the white yashmak of the Moslem, and who was bending forward looking into the room.

"Who is there?" he called. "What do you want?"

"S—sh!"
