He laughed. It made her seem more human, that curiosity about his back.

"Over there," he answered. She looked, and for the first time saw the great shimmering sails gleaming like silver under the moonlight.

She moved towards it, and he followed, noticing without surprise that the heather seemed to make no sign of yielding to the pressure of her white feet.

She halted a little away from it, and he came and stood beside her. Even to Commander Raffleton himself it looked as if the great wings were quivering, like the outstretched pinions of a bird preening itself before flight.

"Is it alive?" she asked.

"Not till I whisper to it," he answered. He was losing a little of his fear of her. She turned to him.

"Shall we go?" she asked.

He stared at her. She was quite serious, that was evident. She was to put her hand in his and go away with him. It was all settled. That is why he had come. To her it did not matter where. That was his affair. But where he went she was to go. That was quite clearly the programme in her mind.

To his credit, let it be recorded, he did make an effort. Against all the forces of nature, against his twenty-three years and the red blood pulsing in his veins, against the fumes of the midsummer moonlight encompassing him and the voices of the stars, against the demons of poetry and romance and mystery chanting their witches' music in his ears, against the marvel and the glory of her as she stood beside him, clothed in the purple of the night, Flight Commander Raffleton fought the good fight for common sense.

Young persons who, scantily clad, go to sleep on the heather, five miles from the nearest human habitation, are to be avoided by well-brought-up young officers of His Majesty's Aerial Service. The incidence of their being uncannily beautiful and alluring should serve as an additional note of warning. The girl had had a row with her mother and wanted to get away. It was this infernal moonlight that was chiefly responsible. No wonder dogs bayed at it. He almost fancied he could hear one now. Nice, respectable, wholesome-minded things, dogs. No damned sentiment about them. What if he had kissed her! One is not bound for life to every woman one kisses. Not the first time she had been kissed, unless all the young men in Brittany were blind or white blooded. All this pretended innocence and simplicity! It was just put on. If not, she must be a lunatic. The proper thing to do was to say good-bye with a laugh and a jest, start up his machine and be off to England—dear old practical, merry England, where he could get breakfast and a bath.
