It was just after supper that she had her first word with him. She had gone out to see the young moon, poised in the clear sky. It hung directly over a shining strip of bay which was visible from where she stood. A dip between the ridges disclosed a sweep of gray-green marshland, a white house or two framed on either side by the pointed firs, and, beyond all, the shining water. She stood looking at it all with an expression of pure delight, and presently was aware that while she was gazing at the scene before her someone was looking at her. She turned with a smile. "Isn't it beautiful, Mr. Williams?" she said. "I never saw anything lovelier than just that." She made a sweep of her arm to indicate the breadth of view.

"It is very fine," he said. "I've always liked that, Miss Elliott. You see I know your name, too."

Gwen smiled. "Oh, but you don't, for I'm not Miss Elliott at all. That is my aunt's name. I am Gwendolin Whitridge. My friends call me Gwen."

The man shivered as if struck by a sudden chill, and backed away from her, but almost immediately he came nearer than before, and stood gazing at her with the intent look she had noticed at the stile. His eyes travelled from the curling tendrils of dark hair about her smooth brow to the tender blue eyes and sweet mouth, then down from the softly firm chin and round white throat to the graceful, slender figure. "I beg your pardon," he said presently, pulling himself up with an effort. "I didn't know. Yes, it is a lovely spot. I hope you will enjoy your summer here." He raised his hat and walked on, leaving the girl half amazed, half amused.

"Rather queer manners," she said to herself. "Yet he speaks like a gentleman, and would be rather nice looking if he had not such a serious face. I never saw such sad eyes, but they did change when I told him my name. I wonder why." However, she did not mention the little episode to her aunt who joined her a moment later.

"Let us walk up to the top of the ridge," Miss Elliott proposed. "We can see the White Mountains from there, and the sunset is glorious."

"There is an eastern sunset, too," said Gwen, looking toward the ocean, where purple, gold and rose were reflected in the water, and where wonderful opalescent clouds floated overhead. "It is a rare place that gives two sunset skies at once," she went on.

"It is like two rings at the circus," returned Miss Elliott. "You want to watch them both at the same time."

"Don't mention such artificial things as circuses when we have this. I want to forget spangles and clowns and sawdust."

"You'll forget soon enough. In a week the outside world will be of no account whatever, I promise you, for, to tell you the truth, we discovered last year that this island is the home of a wizard who gets you in his power, so that once in his clutches, you are bound to come back and while you are here to forget every other place."
