Marietta by F. Marion Crawford

Aristarchi's interference to rescue Zorzi had not been disinterested, and so far as justice was concerned he was quite ready to believe that the Dalmatian had done all the things of which he was accused. The fact was not of the slightest importance in the situation. It was much more to the point that in the complicated and dangerous plan which the Greek captain and Arisa were carrying out, Zorzi could be of use to them, without his own knowledge. As has been told, the two had decided that he was in love with Marietta, and she with him. The rest followed naturally.

After meeting his father and telling him Giovanni's story, Jacopo Contarini had gone to the house of the Agnus Dei for an hour, and during that time he had told Arisa everything, according to his wont. No sooner was he gone than Arisa made the accustomed signal and Aristarchi appeared at her window, for it was then already night. He judged rightly that there was no time to be lost, and having stopped at his house to take his trusted man, the two rowed themselves over to Murano, and were watching the glass-house from, a distance, fully half an hour before the archers appeared.
