There was a moment's silence in the company of which Mme. Fontaine certainly seemed the center. She looked suddenly very Japanese. Against the white of her dress her soft skin gleamed like polished old ivory. Her eyes were darker and more noticeably slanting than ever before. If she only had had dark hair! What country had given her those strangely incongruous locks?

And now it was proposed that they should wander in the garden, and off they started by various paths and bypaths all leading eventually to the little curved bridge at the far end, where Nancy had hung two large yellow lanterns on the ends of supple willow wands.

The Widow of Shanghai walked between Billie and Mr. Campbell, but she had little to say. The moon, swinging over them like another yellow lantern, had glorified the garden into a little earthly paradise. It seemed somehow inappropriate to speak above a whisper in the midst of so much exquisite beauty. The wisteria had opened up during the day and now hung in magnificent purple clusters from an arbor across the main walk.

From the servants' quarters came the tinkle of the samisen, and a breeze laden with the scent of flowers brought with it also the distant sound of voices and laughter.

Nicholas Grimm had joined Billie, and the two young people now lingered in the arbor. In the curve of a path they caught an occasional glimpse of a white dress. The music of Nancy's laugh came to them mingled with Mary's high, sweet note. Gradually the voices died away. The garden seemed to be under a spell. Billie, sitting beside Nicholas in the arbor, waited breathlessly. Then at last in the stillness there burst forth such a stream of full-throated singing as had never been heard.

"It's a nightingale," whispered Nicholas.

Billie felt that she would like very much to cry. Nothing had ever stirred her as this flood of melody which seemed to have been turned on for their especial benefit. While they listened, there came the sound of three pistol shots in quick succession and a cry. Was it an English cry for help?

Instantly Nicholas was on his feet.

"You had better stay here," he said. "I'll run and see what has happened."

Before Billie could reply, Nancy dashed up.
