Stirred by the glimpse of the refined face, and even more by the carriage of the little head under the dainty hat, Keith quickened his pace to obtain another glance at her. He had almost overtaken her when she stopped in front of a well-lighted window of a music-store. The light that fell on her face revealed to him a face of unusual beauty.

Something about her graceful pose as, with her dark brows slightly knitted, she bent forward and scanned intently the pieces of music within, awakened old a.s.sociations in Keith's mind, and sent him back to his boyhood at Elphinstone. And under an impulse, which he could better justify to himself than to her, he did a very audacious and improper thing. Taking off his hat, he spoke to her. She had been so absorbed that for a moment she did not comprehend that it was she he was addressing. Then, as it came to her that it was she to whom this stranger was speaking, she drew herself up and gave him a look of such withering scorn that Keith felt himself shrink. Next second, with her head high in the air, she had turned without a word and sped up the street, leaving Keith feeling very cheap and subdued.

But that glance from dark eyes flashing with indignation had filled Keith with a sensation to which he had long been a stranger. Something about the simple dress, the high-bred face with its fine scorn; something about the patrician air of mingled horror and contempt, had suddenly cleaved through the worldly crust that had been encasing him for some time, and reaching his better self, awakened an emotion that he had thought gone forever. It was like a lightning-flash in the darkness.

He knew that she had entered his life. His resolution was taken on the instant. He would meet her, and if she were what she looked to be--again Elphinstone and his youth swept into his mind. He already was conscious of a sense of protection; he felt curiously that he had the right to protect her. If he had addressed her, might not others do so? The thought made his blood boil. He almost wished that some one would attempt it, that he might a.s.sert his right to show her what he was, and thus retrieve himself in her eyes. Besides, he must know where she lived. So he followed her at a respectful distance till she ran up the steps of one of the better cla.s.s of houses and disappeared within. He was too far off to be able to tell which house it was that she entered, but it was in the same block with Norman Wentworth's house.

Keith walked the avenue that night for a long time, pondering how he should find and explain his conduct to the young music-teacher, for a music-teacher he had decided she must be. The next evening, too, he strolled for an hour on the avenue, scanning from a distance every fair pa.s.ser-by, but he saw nothing of her.

Mrs. Creamer's b.a.l.l.s were, as Norman had once said, _the_ b.a.l.l.s of the season. "Only the rich and the n.o.ble were expected."

Mrs. Creamer's house was one of the great, new, brown-stone mansions which had been built within the past ten years upon "the avenue." It had cost a fortune. Within, it was so sumptuous that a special work has been "gotten up," printed, and published by subscription, of its "art treasures," furniture, and upholstery.

Into this palatial residence--for flattery could not have called it a home--Keith was admitted, along with some hundreds of other guests.

To-night it was filled with, not flowers exactly, but with floral decorations; for the roses and orchids were lost in the designs--garlands, circles, and banks formed of an infinite number of flowers.

Mrs. Creamer, a large, handsome woman with good shoulders, stood just inside the great drawing-room. She was gorgeously attired and shone with diamonds until the eyes ached with her splendor. Behind her stood Mr.

Creamer, looking generally mightily bored. Now and then he smiled and shook hands with the guests, at times drawing a friend out of the line back into the rear for a chat, then relapsing again into indifference or gloom.

Keith was presented to Mrs. Creamer. She only nodded to him. Keith moved on. He soon discovered that a cordial greeting to a strange guest was no part of the convention in that society. One or two acquaintances spoke to him, but he was introduced to no one; so he sauntered about and entertained himself observing the people. The women were in their best, and it was good.

Keith was pa.s.sing from one room to another when he became aware that a man, who was standing quite still in the doorway, was, like himself, watching the crowd. His face was turned away; but something about the compact figure and firm chin was familiar to him. Keith moved to take a look at his face. It was Dave Dennison.

He had a twinkle in his eye as he said: "Didn't expect to see me here?"

"Didn't expect to see myself here," said Keith.

"I'm one of the swells now"; and Dave glanced down at his expensive shirt-front and his evening suit with complacency. "Wouldn't Jake give a lot to have such a bosom as that? I think I look just as well as some of 'em?" he queried, with a glance about him.

Keith thought so too. "You are dressed for the part," he said. Keith's look of interest inspired him to go on.

"You see, 'tain't like 'tis down with us, where you know everybody, and everything about him, to the number of drinks he can carry."

"Well, what do you do here?" asked Keith, who was trying to follow Mr.

Dennison's calm eye as, from time to time, it swept the rooms, resting here and there on a face or following a hand. He was evidently not merely a guest.

"Detective."

"A detective!" exclaimed Keith.

Dave nodded. "Yes; watchin' the guests, to see they don't carry off each other. It is the new ones that puzzle us for a while," he added. "Now, there is a lady acting very mysteriously over there." His eye swept over the room and then visited, in that casual way it had, some one in the corner across the room. "I don't just seem to make her out. She looks all right--but--?"

Keith followed the glance, and the blood rushed to his face and then surged back again to his heart, for there, standing against the wall, was the young girl whom he had spoken to on the street a few evenings before, who had given him so merited a rebuff. She was a patrician-looking creature and was standing quite alone, observing the scene with keen interest. Her girlish figure was slim; her eyes, under straight dark brows, were beautiful; and her mouth was almost perfect.

Her fresh face expressed unfeigned interest, and though generally grave as she glanced about her, she smiled at times, evidently at her own thoughts.

"I don't just make her out," repeated Mr. Dennison, softly. "I never saw her before, as I remember, and yet--!" He looked at her again.

"Why, I do not see that she is acting at all mysteriously," said Keith.

"I think she is a music-teacher. She is about the prettiest girl in the room. She may be a stranger, like myself, as no one is talking to her."

"Don't no stranger git in here," said Mr. Dennison, decisively. "You see how different she is from the others. Most of them don't think about anything but themselves. She ain't thinkin' about herself at all; she is watchin' others. She may be a reporter--she appears mighty interested in clothes."

"A reporter!"

The surprise in Keith's tone amused his old pupil. "Yes, a sa.s.siety reporter. They have curious ways here. Why, they pay money to git themselves in the paper."

Just then so black a look came into his face for a second that Keith turned and followed his glance. It rested on Ferdy Wickersham, who was pa.s.sing at a little distance, with Mrs. Wentworth on his arm.

"There's one I am watchin' on my own account," said the detective. "I'm comin' up with him, and some day I'm goin' to light on him." His eye gave a flash and then became as calm and cold as usual. Presently he spoke again:

"I don't forgit nothin'--'pears like I can't do it." His voice had a new subtone in it, which somehow sent Keith's memory back to the past. "I don't forgit a kindness, anyway," he said, laying his hand for a second on Keith's arm. "Well, see you later, sir." He moved slowly on. Keith was glad that patient enemy was not following him.

Keith's inspection of the young girl had inflamed his interest. It was an unusual face--high-bred and fine. Humor lurked about the corners of her mouth; but resolution also might be read there. And Keith knew how those big, dark eyes could flash. And she was manifestly having a good time all to herself. She was dressed much more simply than any other woman he saw, in a plain muslin dress; but she made a charming picture as she stood against the wall, her dark eyes alight with interest. Her brown hair was drawn back from a brow of snowy whiteness, and her little head was set on her shoulders in a way that recalled to Keith an old picture. She would have had an air of distinction in any company. Here she shone like a jewel.

Keith's heart went out to her. At sight of her his youth appeared to flood over him again. Keith fancied that she looked weary, for every now and then she lifted her head and glanced about the rooms as though looking for some one. A sense of protection swept over him. He must meet her. But how? She did not appear to know any one. Finally he determined on a bold expedient. If he succeeded it would give him a chance to recover himself as nothing else could; if he failed he could but fail.

So he made his way over to her. But it was with a beating heart.

"You look tired. Won't you let me get you a chair?" His voice sounded strange even to himself.

"No, thank you; I am not tired." She thanked him civilly enough, but scarcely looked at him. "But I should like a gla.s.s of water."

"It is the only liquid I believe I cannot get you," said Keith. "There are three places where water is scarce: the desert, a ball-room, and the other place where Dives was."

She drew herself up a little.

"But I will try," he added, and went off. On his return with a gla.s.s of water, she took it.

As she handed the gla.s.s back to him, she glanced at him, and he caught her eye. Her head went up, and she flushed to the roots of her brown hair.

"Oh!--I beg your pardon! I--I--really--I don't--Thank you very much. I am very sorry." She turned away stiffly.

"Why?" said Keith, flushing in spite of himself. "You have done me a favor in enabling me to wait on you. May I introduce myself? And then I will get some one to do it in person--Mrs. Lancaster or Mrs. Wentworth.

They will vouch for me."

The girl looked up at him, at first with a hostile expression on her face, which changed suddenly to one of wonder.

"Isn't this Gordon Keith?"

Gordon's eyes opened wide. How could she know him?

"Yes."

"You don't know me?" Her eyes were dancing now, and two dimples were flitting about her mouth. Keith's memory began to stir. She put her head on one side.

"'Lois, if you'll kiss me I'll let you ride my horse,'" she said cajolingly.

"Lois Huntington! It can't be!" exclaimed Keith, delighted. "You are just so high." Keith measured a height just above his left watch-pocket.

"And you have long hair down your back."

With a little twist she turned her head and showed him a head of beautiful brown hair done up in a Grecian knot just above the nape of a shapely little neck.
