"Lucky man! We poor women have no such distractions. I want to live in the desert," she said eagerly. "I want to sleep in the open under these stars."

Anyone might have made the same remark with no arrière pensée in their words. Mrs. Mervill could not. Her remark contained an invitation; Michael knew it.

"Can you never get away?" she asked. "It would be my expedition, if you would run it for me."

Michael moved from her side, with the pretence of drawing a chair to within speaking distance of her. She had reluctantly to let his wrist slip from her fingers.

"Say you will arrange it," she pleaded. "For weeks I have felt the call of the desert and you know you'd love to come."

"I can't do it," Michael said, almost sternly. "Please don't tempt me
. . . I have work to do."

"Oh, but I will tempt you!" She laughed the soft, low laugh of passion. "By every means in my power. With you it is so difficult to know what will tempt you most. Am I to appeal to the mystic side of you, or to the human? I think the human Michael will suit me best, the Michael who longs to let himself go and enjoy the fullness of Egypt and the wonders of the desert!"

"Don't appeal to any part of me," he said quickly. "Leave me to do my work in the best possible way—try not to act as a disturbing influence."

"Then I have been a disturbing influence?" Michael's voice had betrayed the fact that his work had not been accomplished without difficulty.

"Yes," he said, for the spirit of truth was always uppermost in Michael. "For some days after I left you the last time I found great difficulty in concentrating my mind on my work. . . . I was dissatisfied."
