Marietta by F. Marion Crawford

A little more than an hour later, the gondola came back and stopped alongside the steps of the house. The gondolier had made such haste to obey the summons that he had not thought of going into the house to give the servants warning, and as most of the shutters were already drawn together against the heat, no one had been looking out when he went away. He had asked Pasquale to tell the young master, and that was all that could be expected of him. There was therefore great surprise in the household when Angelo Beroviero went up the steps of his house, and his own astonishment that no one should be there to receive him was almost as great. The gondolier explained, and told him what Pasquale had said.

It was enough to rouse the old man's suspicions at once. He had left Zorzi in charge of the laboratory, enjoining upon him not to encourage Giovanni to go there; but now Giovanni was shut up there, presumably with Zorzi, and had given orders that he was not to be disturbed. The gondolier had not dared to say anything about the Dalmatian's arrest, and Beroviero was quite ignorant of all that had happened. He was not a man who hesitated when his suspicions or his temper were at work, and now he turned, without even entering his home, and crossed the bridge to the glass-house. Pasquale was looking through the grating and saw him coming, and was ready to receive him at the open door. For the third time on that morning, he grinned from ear to ear. Beroviero was pleased by the silent welcome of his old and trusted servant.
