Bianca withdrew her hand. "Yes," she said; "I quite understand. I have always understood." Then, wishing her step-mother good-night, she bent down and kissed her, and passed into her own room, gently closing both of the double set of doors which separated the two apartments.
She had not been in bed long before sleep came to her, for she was, in fact, more weary in body and mind than she had realized. For four or five hours she slept soundly enough, but after that her slumbers became disturbed by dreams. She dreamed that Silvio was near her, that she could see him but could not speak to him, and that he had some message for her, some letter which the Abbé Roux was trying to take from him. In her sleep she seemed to hear strange noises and her own name called softly at intervals. Suddenly she awoke with a start. A gleam of moonlight was shining through the window-curtains and half-closed persiennes. It made a broad track across the floor to the wall opposite her bed, and fell on the face of a picture hanging near the corner of the room—a portrait of that very Cardinal Acorari who had caused the Renaissance palace to be added to the Montefiano fortress, in order that he might have a villa in the Sabine Mountains in which to pass the hot summer months away from Rome. The moonlight glanced upon his scarlet robes and skull-cap and on his heavy countenance. Time had caused the flesh colors to fade, and the full mouth, with the sensual lips, looked unnaturally red against the waxy whiteness of the rest of the face.
Bianca lay and looked at the streak of moonlight on the floor. Presently her gaze followed the track until it rested on the picture. For some moments she looked at the portrait with a certain fascination. She had never seen it in the moonlight before; it looked ghostly. She had once seen a cardinal lying in state when she was a child, and the sight had frightened her. She was not at all frightened now, for she was no longer a child; but all the same, she could not take her eyes off the picture. She found herself wondering what relation she was to that old Cardinal Acorari—great-great-what? Granddaughter would not do, for cardinals, of course, never had children; certainly not cardinal-priests; and Cardinal Acorari had been bishop of Ostia and cardinal vicar of Rome.
Suddenly she sat up in her bed. Surely she had seen the face move? Yes; it had certainly moved; it was quite ten centimetres more to the right of the moonlight than it had been a moment ago. Now half the features were in shadow, and the cardinal's biretta was half red and half black. Sciocchezze! Of course, it was the moon that had moved, not the picture; or, rather, she supposed it was the earth that had moved, or the sun! Something had moved, at any rate, but not the cardinal. And smiling at her own stupidity, Bianca withdrew her gaze from the picture, and, turning on her side, tried to compose herself to sleep once more. But it soon became evident that sleep would not return to her. She felt restless, and the night, too, was hot. Rising from her bed, she threw a light wrap over her shoulders and went to one of the windows, the curtains of which she drew gently aside; and then, taking care not to make any noise that could be heard in the room beyond, she opened the green persiennes outside the window and leaned out. Not a breath of air was stirring, and the September night was oppressively warm. A silvery haze hung over the macchia below the terrace, and far away, under the encircling mountains, Bianca could see the wreaths of mist rising in the valley of the Tiber. The two flanking wings of the palace stood out cold and white in the moonlight, while the double avenue of lofty cypresses on each side of the great night of stone steps leading down from the terrace into the park looked black and sombre in the nearer foreground.
The splashing of a fountain in the centre of the avenue, and the occasional cry of some bird, alone broke the intense stillness. Bianca rested her arms on the ledge of the window, gazing out upon the scene below her. The moonlight fell full upon her and glanced upon the tawny gold of her hair. For some moments she remained immovable. Then, with a gesture of passionate abandonment, she flung her white arms out into the silver night. "Silvio!" she whispered; "Silvio, not one word? Ah, my beloved, if you knew how I want you, if you knew the loneliness! Ah, but I will be patient, I will be brave, for your sake and for my own—only—Dio!—" She turned suddenly with a little cry. Surely she had heard her own name again, spoken very softly from somewhere within the room behind her. She looked hastily round, but could see nobody. Only her own shadow fell across the floor in the moonlight.
"Eccellenza! Donna Bianca!"
Ah, this time she was not mistaken! It was her name she had heard whispered, and the voice came from the cardinal's portrait. Bianca started back. For a second or two she felt fear. If she could only see the person who had called her, she would not be frightened, she was certain of that. Gathering her wrap round her she came forward into the room.
"I am Bianca Acorari," she said, in a low, clear voice. "What do you want with me, and how have you ventured to come here? Speak, or I will call for help."
"Ah, per carità! do not call—do not be afraid."
"I am not afraid," interrupted Bianca Acorari, quietly. "Why should I be afraid? Besides, it—you are a woman, are you not?"
