Felicity Brown belonged to the Midnight Roof Club's famous Aero Octet. That is, of course, a needless bit of information, presumptuous even to the initiate, for everybody knows her, almost everybody. She was the third from the left, the one in new-grass green, with balloons pendant from the scalloped corners of her short, stiff-wired skirt--black balloons like huge dull pearls. The one with the smile. Yes, I know that the others smiled, too, constantly, provocatively; but sometimes the set of their lips was likely to seem anything but the curl of mirth. But not Felicity's. It never lost its challenge. And her dancing was like that, tireless, serenely abandoned, the essence of knowing grace. Half-pagan, half-divine, Denby, the young cover artist, badly smitten, once put it with striking unoriginality. And with exceeding inaccuracy, too. For there are all too many who will insist that the pagan portion rather over-balanced the rest. But her sheer vitality was amazing. An unobserving person, still seeking the key to their intimacy, could easily blunder upon the old bromide and repeat that a pretty woman invariably prefers a plain one for a foil. But he would have to be a very blind fool indeed. For Felicity Brown's beauty, perfect enough under the spot of the Midnight Club's miniature stage, became a less flawless thing in contrast with Cecille. Perhaps that sounds far-fetched. Perhaps, having seen Felicity for yourself, you are inclined to smile and shrug. Nevertheless it is so. Not one of a million Denbys would ever have called Cecille half-pagan or divine in any degree. He wouldn't have noticed her, even, unless his attention had been pointedly called that way. And if another, contemplating her with an eye not greedy of the flesh alone, had finally hit upon the word poignant to describe the hungry youth of her, the odd little tilt of her head, the soft and eager promise in swelling line of hip and breast, Denby himself most certainly would have murmured absently: "Poignant. Yes--yes, poignant. Quite so--quite so!" And yawned. For she did not challenge instantly, as did Felicity. A man might look at her a long time before her perfection smote him. It usually happened that way; it happened exactly like that to Perry Blair. He looked at her many, many times before he saw with seeing eyes and realized how shyly precious and flagrantly bold girlhood like hers could be. Her smile was not as ready as that of the girl who danced. And it had become a little strained, a little edged, before the end. But it never lost its freshness. It was always as shining as fine rain at dawn. And the inquiry in her eyes was not part calculation. They were more wistful, less expectant maybe. But they were steady. And gray as a November sea. Once, remarking the incongruity of their names, Cecille repeated her own with a shade of scorn and provoked from her companion one of the few personalities in which she ever indulged.
