One afternoon, escaping later than usual from the Valentino, Odo had again bent toward the quiet quarter behind the palace. He was afoot, with a cloak over his laced coat, and the day being Easter Monday the streets were filled with a throng of pleasure-seekers amid whom it seemed easy enough for a man to pass unnoticed. Odo, as he crossed the Piazza Castello, thought it had never presented a gayer scene. Booths with brightly-striped awnings had been set up under the arcades, which were thronged with idlers of all classes; court-coaches dashed across the square or rolled in and out of the palace-gates; and the Palazzo Madama, lifting against the sunset its ivory-tinted columns and statues, seemed rather some pictured fabric of Claude's or Bibbiena's than an actual building of brick and marble. The turn of a corner carried him from this spectacle into the solitude of a by-street where his own tread was the only sound. He walked on carelessly; but suddenly he heard what seemed an echo of his step. He stopped and faced about. No one was in sight but a blind beggar crouching at the side-door of the Corpus Domini. Odo walked on, listening, and again he heard the step, and again turned to find himself alone. He tried to fancy that his ear had tricked him; but he knew too much of the subtle methods of Italian espionage not to feel a secret uneasiness. His better judgment warned him back; but the desire to spend a pleasant hour prevailed. He took a turn through the neighbouring streets, in the hope of diverting suspicion, and ten minutes later was at the Professor's gate. It opened at once, and to his amazement Fulvia stood before him. She had thrown a black mantle over her head, and her face looked pale and vivid in the fading light. Surprise for a moment silenced Odo, and before he could speak the girl, without pausing to close the gate, had drawn him toward her and flung her arms about his neck. In the first disorder of his senses he was conscious only of seeking her lips; but an instant later he knew it was no kiss of love that met his own, and he felt her tremble violently in his arms. He saw in a flash that he was on unknown ground; but his one thought was that Fulvia was in trouble and looked to him for aid. He gently freed himself from her hold and tried to shape a soothing question; but she caught his arm and, laying a hand over his mouth, drew him across the garden and into the house. The lower floor stood dark and empty. He followed Fulvia up the stairs and into the library, which was also empty. The shutters stood wide, admitting the evening freshness and a drowsy scent of jasmine from the garden.
