Two explanations of the presence of the mantle in the laboratory suggested themselves to him at once, but the idea that Marietta could herself have been seated in the chair not long ago was so absurd that he at once adopted the other. Zorzi had stolen the mantle, and used it for himself in the evening, confident that no one would see him. To-night he had been surprised and had left it in the chair, another and perhaps a crowning proof of his atrocious crimes. Was he not a thief, as well as a liar and an assassin? Giovanni knew well enough that the law would distinguish between stealing the art of glass-making, which was merely a civil offence, though a grave one, and stealing a mantle of silk which he estimated to be worth at least two or three pieces of gold. That was theft, and it was criminal, and it was one of many crimes which Zorzi had undoubtedly committed. The hangman would twist the rest out of him with the rack and the iron boot, thought Giovanni gleefully. The Governor should see the mantle with his own eyes.
Before he went away, he was careful to fasten the window securely inside, and he locked the door after him, taking the key. He carried the brass lamp with him, for the corridor was very dark and the night was quite still.
Pasquale was seated on the edge of his box-bed in his little lodge when Giovanni came to the door. He was more like a big and very ugly watch-dog crouching in his kennel than anything else.
"Let no one try to go into the laboratory," said Giovanni, setting down the lamp. "I have locked it myself."
Pasquale snarled something incomprehensible, by way of reply, and rose to let Giovanni out. He noticed that the latter had brought nothing but the lamp with him. When the door was open Pasquale looked across at the house, and saw that although there was still light in some of the other windows, Marietta's window was now dark. She was safe in bed, for Giovanni's search had occupied more than an hour.
Marietta might have breathed somewhat more freely if she had known that her brother did not even suspect her of having been to the laboratory, but the knowledge would have been more than balanced by a still greater anxiety if she had been told that Zorzi could be accused of a common theft.
She sat up in the dark and pressed her throbbing temples with her hands. She thought, if she thought at all, of getting up again and going back to the glass-house. Pasquale would let her in, of course, and she could get the mantle back. But there was Nella, in the next room, and Nella seemed to be always awake, and would hear her stirring and come in to know if she wanted anything. Besides, she was in the dark. The night light burned always in Nella's room, a tiny wick supported by a bit of split cork in an earthen cup of oil, most carefully tended, for if it went out, it could only be lighted by going down to the hall where a large lamp burned all night.
Marietta laid her head upon the pillow and tried to sleep, repeating over and over again to herself that Zorzi was safe. But for a long time the thought of the mantle haunted her. Giovanni had found it, of course, and had brought it back with him. In the morning he would send for her and demand an explanation, and she would have none to give. She would have to admit that she had been in the laboratory—it mattered little when—and that she had forgotten her mantle there. It would be useless to deny it.
Then all at once she looked the future in the face, and she saw a little light. She would refuse to answer Giovanni's questions, and when her father came back she would tell him everything. She would tell him bravely that nothing could make her marry Contarini, that she loved Zorzi and would marry him, or no one. The mantle would probably be forgotten in the angry discussion that would follow. She hoped so, for even her father would never forgive her for having gone alone at night to find Zorzi. If he ever found it out, he would make her spend the rest of her life in a convent, and it would break his heart that she should have thus cast all shame to the winds and brought disgrace on his old age. It never occurred to her that he could look upon it in any other way.
She dreaded to think of the weeks that might pass before he returned. He had spoken of making a long journey and she knew that he had gone southward to Rimini to please the great Sigismondo Malatesta, who had heard of Beroviero's stained glass windows and mosaics in Florence and Naples, and would not be outdone in the possession of beautiful things. But no one knew more than that. She was only sure that he would come back some time before her intended marriage, and there would still be time to break it off. The thought gave her some comfort, and toward morning she fell into an uneasy sleep. Of all who had played a part in that eventful night she slept the least, for she had the most at stake; her fair name, Zorzi's safety, her whole future life were in the balance, and she was sure that Giovanni would send for her in the morning.
