Presently, he noticed with some surprise that in spite of a crowded house the two seats next him remained unoccupied; but just before the curtain rose again he turned his head suddenly to discover that one of the seats at least, the one farthest from him, was filled. The recognition of this fact came almost with a shock, a pleasurable shock, for the new arrival was a young and beautiful woman and his first feeling of surprise was shot with approbation at the noiselessness of her entrance, an approbation that he longed to express verbally.

She had slipped past several people, and taken her seat without any of the jingling of chains, rattling of draperies and dropping of small articles which usually proclaim the disturbing appearance of the late feminine arrival, and seem, in fact, her necessary concomitant. But this young woman though she had so recently entered yet managed by some magic at her command to convey the impression of having been in her seat all evening.

Hayden hated to stare at her. He was, in fact, entirely too well bred to do anything of the sort, and yet, quite disgracefully, he longed to do nothing on earth so much, and further he was inclined to justify himself in this social lawlessness.

If women, either wilfully or unconsciously, succeeded in making pictures of themselves, they must expect to be gazed at. That was all there was to the matter. Only, and there was the rub, Hayden couldn't very well profit by the courage of his convictions, in spite of his truculent self‑assurance, for the simple reason that he wasn't capable of it.

The lady was, he decided by virtue of his stolen glances, about twenty‑five years old, although her poise of manner indicated a composure beyond her years. And she was tall and slender, with a straight, regular profile, and dark hair which fell back from her face in soft natural waves, and was very simply arranged. She had, in fact, a simplicity, almost an austerity of what one might call personal effect, which formed a contrast, certainly interesting and to Hayden at least as certainly fascinating, between herself as she impressed one and her very elaborate and striking costume.

Her wonderful gown—even Hayden's untutored masculine senses appreciated its wonderfulness—was of some clinging green material which embraced her in certain faultless lines and folds of consummate art. About the hem it was embroidered with silver butterflies, irregularly disposed yet all seeming to flutter upward as if in the effort to reach her knees. These also decorated her low corsage and spread their wings upon her sleeves. She wore no jewels; and her only ornament was a large butterfly in silver, upon her breast, with diamond‑ and ruby‑studded wings and ruby eyes.

A butterfly! Was he dreaming? Had he thought so much of butterflies that he saw them everywhere? For since his return from South America, Hayden had exhibited a marked interest in butterflies, although, curiously enough, this enthusiasm was not in the least entomological.

But to return to the lady. One foot was thrust a little from her gown, and Hayden was quick to notice that it was encased in a green satin slipper with a buckle which was a replica of the butterfly on her breast, only smaller in size. The whole idea of her costume struck him as fanciful, original and charming; and then—and then—it was only a coincidence, of course; but it started a train of thought which gradually merged into giddier hopes.

His admiration of her seemed to be universal, at least within the confines of the opera‑house, for it was evident that either the lady or her gown, or both, attracted a vast deal of attention to which she on her part was either entirely oblivious or else so accustomed as to be indifferent. At last, she turned toward Hayden a little with a slight change in her expression which he translated as annoyance. He was at once overcome with a swift feeling of embarrassment, of compunction. It seemed to him that he must have sat with his eyes riveted on her. Resolutely, he turned them toward the stage until the poignant sweetness of the intermezzo began to dream through his consciousness as an echo of "that melody born of melody which melts the world into a sea," and then, involuntarily, without premeditation, obeying a seemingly enforced impulse, he had turned toward her and she had lifted her eyes, violet eyes, touched with all regret; and a sudden surprised ecstasy had invaded every corner of his heart and filled it with sweetness and warmth, for the music, that enchanting, never‑to‑be‑forgotten intermezzo, had revealed to him—the fairy princess.

In a moment that he dreamed not of, around some unexpected corner of life, she had turned her feet and he, crass fool that he was, was not sure that it was she; like all faithless generations, he had waited for a sign, until at last, in the ebb and flow of the music, she had lifted her sweet eyes and he had known her finally, irrevocably, and for ever.
