When they returned in the spring, I heard that they had bought the Brereton house, for what seemed to my inexperienced ears a very large sum. But Ned, whom I met one day at the club, explained to me convincingly that it was really the most economical thing they could do. "You don't understand about such things, dear boy, living in your Diogenes tub; but wait till there's a Mrs. Diogenes. I can assure you it's a lot cheaper than building, which is what Daisy would have preferred, and of course," he added, his color rising as our eyes met, "of course, once the Academy's going, I shall have to make my head-quarters here; and I suppose even you won't grudge me a roof over my head." The Brereton roof was a vast one, with a marble balustrade about it; and I could quite understand, without Ned's halting explanation, that "under the circumstances" it would be necessary to defer what he called "our work--" "Of course, after we've rallied from this amputation, we shall grow fresh supplies--I mean my wife's investments will," he laughingly corrected, "and then we'll have no big outlays ahead and shall know exactly where we stand. After all, my dear fellow, charity begins at home!" IV THE Halidons floated off to Europe for the summer. In due course their return was announced in the social chronicle, and walking up Fifth Avenue one afternoon I saw the back of the Brereton house sheathed in scaffolding, and realized that they were adding a wing. I did not look up Halidon, nor did I hear from him till the middle of the winter. Once or twice, meanwhile, I had seen him in the back of his wife's opera box; but Mrs. Halidon had grown so resplendent that she reduced her handsome husband to a supernumerary. In January the papers began to talk of the Halidon ball; and in due course I received a card for it. I was not a frequenter of balls, and had no intention of going to this one; but when the day came some obscure impulse moved me to set aside my rule, and toward midnight I presented myself at Ned's illuminated portals. I shall never forget his look when I accosted him on the threshold of the big new ballroom. With celibate egoism I had rather fancied he would be gratified by my departure from custom; but one glance showed me my mistake. He smiled warmly, indeed, and threw into his hand-clasp an artificial energy of welcome--"You of all people--my dear fellow! Have you seen Daisy?"--but the look behind the smile made me feel cold in the crowded room. Nor was Mrs. Halidon's greeting calculated to restore my circulation. "Have you come to spy on us?" her frosty smile seemed to say; and I crept home early, wondering if she had not found me out.
