With a vague feeling of disappointment through all his elation, Hayden turned the note over in his hand. At the head of the page was embossed a silver butterfly, but beyond this clue there was nothing to indicate the lady's identity; no name, no address. Again he read the brief words written in a clear, upright hand, which so plainly showed strength of character and unusual self‑control, but gained no new light.

What an odd happening! He felt indefinably chilled. Why this appointment for a meeting at one of the large hotels? Curious. Why this mystery, anyway, he thought irritably; why this excess of mystery? And yet, after all, he was forced to confess to his inmost soul that, mystery though it was, he did not find it any the less delightful for that, rather the more so.

He had never known so slow a day. The minutes lagged unaccountably, the hours crawled forward at the most snail‑like pace, and his impatience at this was tempered to a satirical amusement by the fact that the entire world of his friends seemed banded together in a conspiracy to engage his society for that particular evening.

He had, as night drew on, a breathless and excited sense of eluding and escaping them, and dressed with the emotions of the criminal who realizes that the sleuths are hard upon his trail. It is unnecessary to say that he was early at the Gildersleeve, and managed to secure a table which commanded a view of the entire room. He had an hour and a half before eight o'clock, and he put as much of it in as possible in ordering a carefully chosen dinner, taking an incredible time over it, for, as the fever of his anticipation ran high, his manner became the more cool and leisurely, a temperamental trait of his.

He ate his soup as slowly as possible, and glanced about at the tables now rapidly filling up with all the laughing groups of men and women who would be going on to the theater and the opera a little later. The music was charmingly subdued; a whiff of fragrance from the flowers on his table reached him. He liked the atmosphere of this hotel, quiet, restful, and handsome after a restrained and sober fashion; and then, all at once, the surroundings, the groups at the tables, the waiters passing to and fro, the appealing music, the noise and hum of conversation lost life and motion and color, and became the mere tapestry against which she alone moved.

It was about half‑after seven when the vigilant eye which Hayden had kept so persistently on the door was rewarded; but to his disappointment, she was not alone, but was accompanied by an elderly, gray‑haired man. However, his spirit was somewhat restored by the fact that they took a table immediately within the line of his vision. She wore black to‑night, gauzy and diaphanous black. A small black toque with some upstanding silver trimming rested on her hair, and the silver butterfly on her breast seemed to flutter its delicate, shining wings; but depending from it almost to her waist and encircling her neck, was an exquisite chain of small, enameled butterflies. They were in all shades of yellow and orange, with touches of black, and were held together by tiny, jeweled links. Butterflies, more butterflies! Could it be? Was it a possibility? Hayden cautioned himself lest his imagination ran away with him.

He could not fail to notice that here, as at the opera, she was again an object of interest. Every one in the room seemed to be either openly or furtively gazing at her. In this, he reflected, there was nothing very peculiar, as her beauty, which was sufficiently marked to compel interest anywhere, was not more noticeable than the unique and remarkably beautiful ornaments she was wearing.

The man with her, unobtrusive and gray enough in all conscience to escape any attention whatever, yet made a peculiar impression on Hayden. As he sat, apparently ordering dinner in haste, with his watch in his hand, so to speak, Hayden was struck by the deference he displayed to the lady he accompanied, and the lack of ease in his manner. He was like a man who had been unwittingly drawn into a situation which rendered him extremely uncomfortable, and he was distinctly not of her world. On the other hand, the lady of the silver butterfly, as Hayden was forced to call her, in lieu of any other name, exhibited her usual calm, unruffled composure.

Hayden could not notice, watch her as closely as he would, that she showed even curiosity as to whether or not he was in the room. Not once did he succeed in surprising the smallest glance in his direction. Instead, for the most part, she talked earnestly to the man opposite, who had evidently ordered his dinner of dishes ready to be served, and was hastily consuming them, while she had given more time to her order, and did not really begin her dinner until her vis‑à‑vis had disposed of his. Then, with a final and hasty glance at his watch, the gray and elderly man arose, bowed awkwardly and formally to her and left the room.

The first course of the lady's dinner had just been placed before her, and Hayden could not fail to admire the way in which she bore herself. Although, as at the opera, she must have been conscious of the many admiring eyes cast in her direction, she gave no evidence of it, and he was almost equally piqued by the fact that she manifested no apparent interest in his presence. Not once did she turn her head toward the door, not once did she incline her eyes in his direction.
