"I thought I should see a butterfly," he said, "a butterfly that had flown up from the land of eternal summer, and you're only a chrysalis."

"It's too cold for butterflies up here," she laughed. "Wait until I get down to the warm hall." But although she returned his banter, she did not look at him, her eyes were downcast, and on the drive down the hill she scarcely spoke. Seagreave was one of those rare persons who respect another's mood of silence, and consequently he did not notice this new constraint which had overfallen her.

The hall, lighted with bull's-eye lanterns, was crowded with people, every one of the chairs taken and every inch of standing room occupied. There was no platform, but the space upon which Pearl was to dance was screened off by red curtains.

But even before she entered the little dressing booth prepared for her, she hastened to peep through the curtains, scanning the audience with an eager eye. Her face fell as she saw that Hanson, true to his promise, was there, and on one of the front seats, not far from Seagreave and Bob Flick, who were sitting together. His eyes were dull, his face flushed, and he lurched flaccidly in his chair; he had been drinking heavily all day.

He was wondering dully as he sat there if she would enter in the same indifferent manner that she had adopted the first night he had seen her down in the desert. Probably she would; it had been very effective.

But the time for conjecture was over. The curtains were drawn aside, and Hugh sat down at the piano and began to play a seductive, sensuous accompaniment. Then through a crimson curtain at the rear Pearl flashed in as if blown by the mountain wind. The chrysalis had cast aside its shell and this tropical butterfly had emerged. Her skirts were of yellow satin, and from a black bodice her beautiful bare shoulders rose half revealed and half concealed by her rose-wreathed, white manton de Manila. In her black, shining hair, just over one ear, was a bunch of scarlet, artificial blossoms.

She floated about the floor for a moment or two like a thistle-down blown hither and thither by the caprice of the wind, scarcely seeming to touch the ground, upborne by the music-tide. Throughout her career she was always at her best when she took those first few moments about the stage and waited for her inspiration.

Then she drifted nearer to Hughie and murmured, "The Tango." He changed his tempo immediately, and almost without a pause of transition she began that provocative measure—the dance of desire. Thrilling with the joy of expressing her love, her beautiful new love for Seagreave, through her art, she danced with a verve, an abandon, a more spontaneous impulse than she had ever shown before. The Tango! She made it a thing of alluring advances, of stinging repulses, of sudden, fascinating withdrawals and exquisite ardors.

When the applause had finally died down, the hall was still noisy with a babel of voices; those who could, moved about in the crowded space, and little groups formed and broke up. Bob Flick, speaking to this or that acquaintance, felt some one touch him lightly on the arm, and turned suddenly to see Hanson standing beside him.

"Hello, Flick," with a sort of swaggering bravado, "our old friend, the Black Pearl, is going some to-night, ain't she?"
