Striding up and down the platform to which he had bought early access by one of those large fees for which the travelling American of a certain type is famed, Vanderlyn, with his long lean figure, and stern pre-occupied face, did not suggest, to the French eyes idly watching him, a lover,--still less the happy third in one of those conjugal comedies which play so much greater a part in French literature and in French drama than they do in French life. He had thrust far back into his heart the leaping knowledge of what was about to befall him, and he was bending the whole strength of his mind to avert any possible danger of ignoble catastrophe to the woman whom he was awaiting, and whose sudden surrender was becoming more, instead of less, amazing as the long minutes dragged by. Vanderlyn's mind went back to the moment, four short days ago, when this journey had been suddenly arranged. Mrs. Pargeter had just come back from England, where she had gone to pay some family visits and to see her little son, who was at a preparatory school; and the American diplomatist, as was so often his wont, had come to escort her to one of those picture club shows in which Parisian society delights. Then, after a quarter of an hour spent by them at the exhibition, the two friends had slipped away, and had done a thing which was perhaps imprudent. But each longed, with an unspoken eager craving, to be alone with the other; the beauty of Paris in springtime tempted them, and it was the woman who had proposed to the man that they should spend a quiet hour walking through one of those quarters of old Paris unknown to the travelling foreigner. Eagerly Vanderlyn had assented, and so they had driven quickly down the Rue de Rivoli, right into the heart of that commercial quarter which was the Paris of Madame de Sevigne, of the bitter witty dwarf, Scarron, of Ninon de l'Enclos, and, more lately, of Victor Hugo. There, dismissing their cab, they had turned into that still, stately square, once the old Place Royale, now the Place des Vosges, of which each arcaded house garners memories of passionate romance. Walking slowly up and down the solitary garden there, the two had discussed the coming August, and Margaret Pargeter had admitted, with a rather weary sigh, that she was as yet quite ignorant whether her husband intended to yacht, to shoot, or to travel,--whether he meant to take her with him, or to leave her at some seaside place with the boy. As she spoke, in the low melodious voice which still had the power to thrill the man by her side as it had had in the earlier days of their acquaintance, Mrs. Pargeter said no word that all the world might not have heard, yet, underlying all she said, his questions and her answers, was the mute interrogation--which of the alternatives discussed held out the best chance, to Vanderlyn and herself, of being together?
