The opening bars of a waltz sounded through the house above the irregular murmur of conversation, bearing their promise and summons along festal corridors and into garlanded nooks and alcoves. Paul Middleton drew a breath of relief as the girl to whom he had been talking was carried off to dance, for she had bored him intolerably. The refreshment room, crowded a moment ago, was thinning down, and, glad of the respite, he took another sandwich and slowly sipped the remainder of his coffee. His humour was of the worst. If his hostess had not been his mother's oldest friend, he would never have allowed himself to be persuaded to accept her invitation after he had once decided to decline it. Why had his mother so persisted, when she knew very well he was looking forward to playing in an important chess match? Certainly the evening so far had not compensated him for the pleasure he had thus missed.

He had been chafing the whole time, and intermittently he had played with the idea of slipping out and taking a hansom down to the chess club. But he had ticked off five dances on Celia's programme—Celia was of course Celia—and he was to take her to supper. Moreover, on his arrival at the small-and-early, Mrs. Saxon had led him round—he feeling that his amiable expression made him a hypocrite—and, mechanically repeating his request for the pleasure of a dance, he had scrawled his name on several programmes with scarcely a glance at their owners. It was, however, more particularly his engagements with Celia, and one or two other girls he knew well, that had made him stay on. Once more he glanced at his watch. It was getting well on towards midnight now, and the issue of the chess match must already have been decided. After some speculation as to the winning side, he resigned himself to finishing the evening where he was.

At the best of times Paul Middleton's interest in the ballroom was only lukewarm. He frankly professed not to care about it at all, and, though he was in the habit of dancing every dance, he looked upon himself more as a spectator than a participator on such rare occasions as he accepted cards for. He had no favourite partners. Into the inner and intimate life of that circle of light made for human pleasure he could never enter; he had always shrunk from exploring its labyrinth of flirtation, coquetry, and petty manoeuvring, the very thought of the intricacies of which affrighted his plain-sailing temperament. To him one girl in a ballroom was much the same as another—a green, white, or pink gown with sometimes an eye-glass attached. He knew very well, though—if only from his mother having instilled it into him—that no such indifference attached to him, a young man of twenty-three, who was absolute master of at least eleven thousand pounds a year, and not without claim to other merits.

Becoming aware that the music was in full swing upstairs, he began to think it was high time to look for his partner. But the name "Brooke" on his programme, which he made out with some difficulty, called up no picture, no living personality. He could not even recollect the moment when he had written it, and it did not appear he had made any note to help him identify the girl. His last partner had had to be pointed out to him by Mrs. Saxon, and he did not care to trouble her again. "Besides," he reflected, "this Miss Brooke, whoever she is, will most likely be hidden away in some nook or other and will be only too glad not to be hunted up."

He had almost made up his mind to skip the dance when there came into the room an old schoolfellow, more or less a friend of his. The two interchanged a word. Thorn, it appeared, wanted a whisky and soda before going home. He had to turn in early to be in good form for the morrow's cricket. It was the first match of the season, and he was anxious to do brilliantly. Paul took the opportunity of asking him if, by any chance, he knew or had danced with a Miss Brooke.

"The beautiful Miss Brooke you mean, don't you?" asked Thorn.

Paul explained he didn't know which Miss Brooke he meant, but that he ought to be dancing with a Miss Brooke. Any girl who answered to that name would satisfy him.

"Well, if the one you mean, or don't mean, is the one I mean, she's just outside the door talking to a big Yankee chap. I never heard of her before to-night, but she's a stunning girl. She's the daughter of some American millionaire, a railway king, or something of that sort—at least everybody says so. I tried to get a dance with her, but I wasn't in luck. I envy you. Good-night, old boy!"

"I suppose, then, I must consider myself in luck," thought Paul, staying yet a moment as he caught sight of his full reflection in a glass. It was a medium, slightly built figure that met his gaze, easy and graceful of carriage. The face was fair with a tiny light beard—the silken hair cut short, the features intelligent, the eyes grey, the teeth beautiful. A suspicion of a freckle here and there did not seem unsuited to the type of complexion. The survey seemed to please him, and he stepped forward with the intention of taking possession of "the beautiful Miss Brooke."

Thorn's indication proved correct. To his surprise Miss Brooke seemed to recognise him as he approached, for she welcomed him with a smile, from which he deduced, moreover, that she must have been waiting for him. He had a general sense of enchantment and diaphanousness, of a delicate harmony of colour-tones; an impression as of an idealised figure that had stepped out of a decorative painting. He wondered how he had escaped the impression at the time of his introduction to her, and, despite her smile, he was chilled by a doubt that it might, after all, be some other Miss Brooke on whose programme he had written. Of the man she had been talking to he scarcely took any note at all, beyond verifying he was a "big Yankee." He took her up to the dancing-room, and they began waltzing. Paul considered himself a pretty good dancer, and there were even moments when he could conscientiously say he was enjoying himself. But somehow he found himself going badly with Miss Brooke. Things seemed to be wrong at the very start. There was an uncomfortable drag. Paul was compelled to take enormous steps to counteract it, and after a dozen turns both agreed to give it up.

"You dance the English step, of course, Mr. Middleton," she observed as they sauntered round. Her American accent was of the slightest, and few as were the words she had so far spoken, they seemed to Paul subtly to vibrate with a pleasant friendliness. Her voice was sweet and clear, with an under-quality of softness and caress. The suggestion that there were waltz steps other than the one he was wont to dance was new to him.

"I suppose mine is the English step," he replied, "though I never heard of any other. Is yours very different?"

"Oh, yes. We Americans really waltz, whilst you English just go round and round and round, with your stiff legs for all the world like a pair of compasses."

Paul could not agree with her, and patriotically proceeded to defend the English waltz, surprised to find himself expending oratory on so trivial a subject. He asserted it was not the mere monotonous turning to which Miss Brooke would reduce it, but that a spirit went with it; whereupon Miss Brooke shook her head, declaring she had shown the American step to a good many English people, and, no matter how sceptical before, they had vowed, one and all, never to dance the English step again.

They had wandered away from the mass of rotating figures and taken possession of a couple of seats in a corner outside the dancing-room. Paul had now an opportunity of observing Miss Brooke more narrowly. Other partners he had already forgotten. He could hardly have identified them again. So far as he was concerned, they had got completely lost in the crowd from which they had temporarily emerged. But of Miss Brooke he felt sure a perfectly definite picture would remain in his mind. What struck him most at once was a certain spirit of frank good humour that seemed to exhale from her, that made him feel, even with her first few words, as if she were merely resuming an interrupted conversation with him. Her manner suggested the natural falling-into-step by the side of an established friend, overtaken en route, and it was hard for him to realise this was really their first talk together.

Paul had never danced with an American girl before, else he would have been aware of the incompatibility of their steps. His notions of the American girl—or at least the American girl that comes to Europe—were of the vaguest. He had in the course of his existence met perhaps two or three of the class, but he had never really talked to them. He had heard the American girl spoken of—praised, damned, or tolerated; he had read about her push and businesslike qualities; and a short time since he had seen the type portrayed on the stage—a dashing, masterful creature, a piece of egotism incarnate, with a twang as pronounced as her self-assertiveness, a terrible determination, and an equally terrible assurance of carrying it through. But he had never thought about her coherently; never consciously crystallized these more or less contradictory notions of her that had come to him in so scattered and chaotic a fashion. It was quite certain, however, that Miss Brooke had nothing in common with the monstrosity that had given so much delight to that English audience, and raised in it a due consciousness of its own virtue of modest moderation. Nor could he associate her with the dreadfully improper and unabashable person he had heard more than one British matron declare the American girl to be.

Miss Brooke did not address her words to the floor, but sitting with her chair at an angle to his, looking straight at him as she spoke. Paul found the ordeal a fascinating but sufficiently trying one. He had no chance against this wonderful girlish face, with its sparkling blue eyes and its subtle quality of sincerity and spirituality; tantalising by the charm of its smile, which suggested moments of wickedness and kissing, and provoking by its air of unawareness of its calm-destroying powers. He was conscious, too, of a long, white neck rising above a pair of well-knit shoulders, out of a mass of white fluffy trimmings, in which were set with careless art a few deep-red velvet flowers. On her forehead lay two roguish curls that moved freely, and each temple was covered by a bewitching lock, whose end curled inwards toward the ear. At the back her hair was drawn right up into curls, leaving the whole neck free, and showing the contour of the gracefully-poised head. Her white gown seemed woven of some fairy substance, embroidered with myriad gold spots, and encircled round the waist with three golden bands. The pink, round flesh of the upper arm showed firm and cool through the web of the sleeve that met the long white glove at the elbow. The bodice followed closely the modelling of the bust, and the skirt swept downwards, ending in a mass of foam-like fluff amid which nestled the tips of two neat shoes. Altogether a superb girl, dainty and supple, without any suggestion of fragility.

The comparative merits of the English and American waltzes were still occupying their attention.

"Now, tell me, Mr. Middleton," she asked, after enthusiastically descanting on the pleasure and grace of the "long glide," "haven't I really converted you?"

"I want very much to be converted, but your waltz seems formidable. I am afraid of it."

"I'm sure it would not take you long to learn. Cannot I really coax you into a promise to try it? I enjoy making converts—I have missionary tendencies in the blood."

"That's interesting. Because there are tendencies in my blood, too. Anti-missionary ones, however. To be true to the family tradition, I'm not sure whether I ought not resist your coaxings."

"Which I'm sure you're not going to do." Her face took on an expression of mock imploration. "But, tell me, how far back does your tradition go, and how did it arise?"

"It began with my grandfather, whose pet idea was that the energy and money spent on missions should be employed at home for the raising of the lower classes. My father went a step further by deciding the particular form in which the lower classes should reap the benefit, and he died with the hope that the dream of two generations should be realised by me."

"There is quite a touch of poetry in what you tell me," said Miss Brooke. "My family history is more prosaic, but it has a dash of adventure in it. The missionary hobby began with my great-grandfather, who was devoted, body and soul, to it—certainly body, for he was eaten by cannibals. Poor savages!"

"Poor savages!" echoed Paul, for the moment supposing Miss Brooke meant to throw doubts on her ancestor's digestibility.

"Yes, for grandfather went out to preach to them! A very mean revenge, I call that."

"How do you reconcile that statement with your own missionary leanings?" asked Paul, thinking it strange a railway king should be the son of an earnest missionary, and vaguely speculating whether the millionaire was in the habit of giving large sums to "revenge" his grandfather.

"Oh, as a woman I have the right to make contradictory statements. 'Tis a valuable right, and I find it very convenient not to yield it up, though I did learn logic at college."

"But surely it must be ever so much nicer to triumph by logic."

"If one were only sure of triumphing! But I am really in no difficulty, so you will not get an exhibition of logic to-night. My missionary tendencies are purely a matter of instinct, my anti-missionary ones a matter of sentiment. Do not instinct and sentiment pull different ways in human beings? Confess, Mr. Middleton, don't you often want to do things you feel you ought not?"

"More often I don't want to do things I feel I ought to."

"That is a piece of new humour."

"I meant the inversion seriously. But I'm glad to find that we are agreed at least in sentiment."

"And I do try and turn the instinct into useful channels. Americans, you know, never let force run to waste. Now, you will learn that waltz, won't you, Mr. Middleton? Promise me quickly, as some one is coming to take me to dance. There comes the top of his head."

"Dear me, has the next dance come round already!" ejaculated Paul. "You may consider me a sincere convert," he added quickly, "if—if you will spare me another dance."

"If you can find one," she replied; and, slipping her programme into his hand, she rose in response to the smile of the newcomer. To Paul's surprise, the man was the same from whom he had carried off Miss Brooke only a minute or two ago, as it appeared to him. Which fact caused him now to take keen notice of him. "The fellow" was quite six feet high, and of slim, supple build. His face was dark, and, to Paul, distinctively American. He wore a short pointed beard and a carefully-trimmed moustache. His black hair somewhat eccentrically hung down in lines cut to the same length. His eyes gleamed with an almost unnatural brightness, and his teeth showed themselves polished and white.

"Write thick over somebody else's name." Paul was conscious of Miss Brooke speaking to him in almost a whisper; then in a moment she had bowed and moved off. He could not help feeling angry with the man for taking her away, and his displeasure showed itself in his face. There seemed, too, something proprietorial in the way "the confounded fellow" walked off with her, and a thousand foolish conjectures hustled in his brain. However, he remembered he had Miss Brooke's programme, which, together with her last injunction, formed a comforting assurance she had taken him into special favour. It had been decidedly nice to talk to this girl, who seemed just the sort of person—simple and straightforward despite her wonderful charm—he felt he could get on with, and it gave him pleasure to picture her again sitting by his side, fresh, cool, sweet, and surpassingly beautiful.

After lingering a little he went into the ballroom again. Miss Brooke's figure alone drew his eye—the rest of the world was a mere dancing medley. She was obviously enjoying her dance, and Paul found himself envying her partner his easy mastery of the American waltz step. He could not help observing now what a superb note she struck in that crowd. He could see, too, she was being noticed, and divined talk about her by many moving lips.

He found an opportunity of returning her programme, which she received with a marked look of surprise that changed into a smile of thanks. Paul was much puzzled. Her manner seemed to make it appear that she had dropped the programme and he had picked it up. He rather resented this, till it occurred to him she had slipped it into his hand so as not to be seen by her present cavalier, and probably she had played this little comedy because she did not want to rouse his suspicion. Paul's fears that the man might be something to her were reawakened, but they were palliated by a sense of triumph over him. Had not Miss Brooke played a part—for his sake?

Mrs. Saxon passed near him and stopped to talk to him a moment. He made absent-minded replies—indeed, five minutes later he recalled that he had said something particularly foolish and hated himself. In this mood he sought cousin Celia and took her to supper. He examined her more critically now, finding her handsome, solid, and only passably interesting. He noted, too, that her manner lacked sprightliness and enthusiasm, and that the things she talked about didn't interest him in the least. He found himself apologising again and again for not having heard what she said. That was whenever there were questions for him to answer. He had, however, enough wit left to feel it was fortunate she did not ask questions more frequently. Meanwhile his eye wandered constantly towards a little table some distance off, which Miss Brooke and her American friend had all to themselves, the other two covers being as yet unappropriated. Once or twice he became aware that Celia's eye was following his. He saw a gleam of understanding flash across her face, followed by a flush whose meaning was obvious. But somehow he felt reckless.

An hour later he was with Miss Brooke again. At her laughing suggestion they had found a hiding-place, more "towards the upper regions," in order to keep out of the way of the man whose name had been written over, and who, indeed, never appeared. Miss Brooke was admiring an exquisite little painting of a picturesque boy looking over a rude wooden bridge on to a small stream. The work, which hung just opposite them, bore a well-known French signature, and had attracted her attention at once. The enthusiasm with which she spoke of the artist led Paul to inquire if she herself painted.

"I try to," she answered self-deprecatingly. "I am appallingly interested in my work. I always lose myself when talking about it."

She was evidently serious, and Paul was glad to have struck such a mood, which promised possibilities of intimate conversation.

"You have taken up art seriously?" he asked.

"One must do something to fill one's life," she replied, with unmistakable earnestness; and set Paul musing about the inability of fortune to compensate for a want of purpose in life, as he had, indeed, felt long ago. That a woman, however, should give expression to the sentiment surprised him. Her next words astonished him still more.

"I have always been ambitious, and I might have achieved something in art if I hadn't wasted so many years trying other things."

"But, surely you must find the knowledge you have acquired worth having."

"I would willingly exchange it all for two years' progress in my work. The mistakes began by poppa discovering I was a musical genius, and as I was just mad to do something big in the world, I believed him. The next discovery was mine—that I was a great writer, and when, two years after that, an artist friend declared some sketches of mine were full of inspiration, my enthusiasm for writing fizzed out immediately, and I rushed into painting, and over to Paris to study. Of course, I'm only in the student stage, but my professor has given me distinct encouragement. In my heart I really believe I should succeed if only——" She broke off with a curious laugh, but went on almost immediately: "If only I don't transfer my enthusiasm to sculpture before long. You see I know my little ways. Besides, the temptation to change is as strong as it possibly can be. It would be such a distinction to have completed the round of the arts."

"Poetry would still be left untouched."

"Oh, I've written poetry as well. That was part and parcel of my literary mania."

"And naturally expired with it."

"No. Let me confess. Poetry is the one thing I keep up in order to be able to feel I am made of fine stuff. It's the one unsaleable thing I devote my time to, and without it I should feel utterly ignoble. With all my ambition to achieve greatness, I am quite unable to say how much of my enthusiasm is due to the hope of accompanying dollars."

Paul was startled for a moment, then laughed in high amusement at the idea of a railway king's daughter eking out her income by Art.

"I mean it. I'm not as noble as I look, but thank you for the compliment all the same. If I have allowed myself any illusions on the point, they were all dissipated when I heard of the price a Salon picture sold for last year. My feeling of envy was too naked to be mistaken—naked and unashamed. I don't know if you've ever experienced the sort of thing—whether you've ever written poetry to keep your self-respect."

"I fear writing poetry would be no test for me. I don't mean to imply that the result would not be unsaleable," he added, smiling, "but that I am not so avaricious as you profess to be. I am quite satisfied that my work in life shall bring me no return."

"I wish I were as fine as that," said Miss Brooke.

"I am afraid I am far from being fine," said Paul, modestly. "I am simply content with my fortune. As you said before, one must do something to fill one's life. I am only too grateful for the prospect of being able to employ my energies. So you see I am really selfish at bottom."

"We each appear to have a due sense of the clay in us, so let us agree we are neither of us precisely the saints we appear. But you've not yet told me in what particular way you purpose satisfying that selfishness of yours."

"Thereby hangs a long tale," said Paul, laughing again. "It is connected with the family tradition I mentioned to you before."

"I remember. Your father laid some injunction on you about converting missionary energies and subscriptions for home use."

"That is a quaint way of putting it. It is true his injunction first set me thinking, and it led to my developing certain Utopian ideas of my own. As the result, I am now studying architecture. No doubt you will think it a strange choice. There begins another dance, and we've both partners."

"How vexatious!" said Miss Brooke. "Just when I am so interested. I am really longing to hear all about your Utopia."

"I should so much have liked to tell you," murmured Paul, thinking he might even have sat out another dance if it were not for his foolish exclamation.

"Oh, but you're going to call, Mr. Middleton."

"I shall be very happy," said Paul, repressing a start.

She wrote her address for him on the back of his programme, adding, "I shall be in on Wednesday afternoon."

He thanked her and took her down to the dancing-room where she was pounced upon immediately, and he then discovered, to his surprise, that he and Miss Brooke had sat out two dances! Moreover, the frown which Celia gave him over her partner's shoulder as she waltzed by made him refer to his programme, when he found he had overlooked the little tick at the side of dance number fourteen.
