The night was radiant. Sky and houses and bay were aglow with her silver beams. Merry groups were passing to and fro. There was music, singing, happiness,--all the gentleness of a perfect night. Francesco walked more slowly in the moonlight. Suddenly a couple passed him: a man and a woman. The woman wore a crimson cloak, and in passing she looked up into his face. It was only a moment's meeting; but all the color had faded from Francesco's cheeks. He looked back: they had disappeared among the throngs. For a moment he stood still as one paralyzed. Could his eyes have deceived him? Impossible! He could never mistake that face, nor was there another like it on earth! He faltered, stopped, recovered himself, then retraced his steps in search of the two. But his efforts were utterly in vain. As one dazed he returned to the inn. The convent bells of Santa Lucia, pealing the midnight hour, found him pacing up and down within the narrow confines of his chamber. Now and then he paused and looked out into the night. Only when the noise and merriment had died to silence he sought his couch, but it was long ere sleep would come to him. For in the woman with the unknown cavalier, who had passed him without recognition, he had recognized Ilaria Caselli. CHAPTER II THE LADY OF SHADOWS It was early on the following day when Francesco took the direction of the palace. The city appeared gay and bright; the beautiful isles of Ischia and Capri, like twin outposts guarding an earthly paradise. He had arrived at the hour of dusk, which had soon faded into the swift southern night, and much of the magic of the scene had thus been veiled before his gaze. Now he saw and marvelled. All around stretched the bay in its azure immensity, its sweeping curves bounded on the left by the rocky Sorrentine promontory, with Sorrento, Meta and a cluster of little fishing villages, nestling on the olive-clad precipices, half hidden by orange groves and vineyards and the majestic form of Monte Angelo towering above. Farther along the coast rose Vesuvius, the tutelary genius of the scene, its vine-clad lower slopes presenting a startling contrast to the dark smoke-wreathed cone of the mountain. On the right the graceful undulations of the Camaldoli hills descended to the beautifully indented bay of Putcoli, while Naples herself, with Portici and Torre del Greco, reposed as a marble quarry between the blue waters of the bay. Beyond, in the far background, the view was shut in by a phantom range of snowy peaks, an offshoot of the Abruzzi mountains, faintly discerned in the purple haze of the horizon.
