"In that case, signor, I shall feel that my mission has not been unsuccessful, however mistaken I may be, and I trust sincerely that I am wholly wrong. I thank you much for the kind way in which you have heard me express suspicions of a person in your confidence."
The gravity with which the merchant had heard Francis' story vanished immediately he left the room, and a smile came over his face.
"Boys are boys all the world over," he said to himself, "and though my young friend has almost the stature of a man, as well as the quickness and courage of one, and has plenty of sense in other matters, he has at once the prejudices and the romantic ideas of a boy. Had Signora Castaldi been young and pretty, no idea that she was treacherous would have ever entered his mind; but what young fellow yet ever liked a gouvernante, who sits by and works at her tambour frame, with a disapproving expression on her face, while he is laughing and talking with a girl of his own age. I should have felt the same when I was a boy. Still, to picture the poor signora as a traitoress, in the pay of that villain Mocenigo, is too absurd. I had the greatest difficulty in keeping my gravity when he was unfolding his story. But he is an excellent lad, nevertheless. A true, honest, brave lad, with a little of the bluffness that they say all his nation possess, but with a heart of gold, unless I am greatly mistaken."
At seven o'clock, Francis was just getting into his gondola to go round again to Signor Polani's, when another gondola came along the canal at the top of its speed, and he recognized at once the badge of the Giustiniani. It stopped suddenly as it came abreast of his own boat, and Matteo, in a state of the highest excitement, jumped from his own boat into that of Francis.
"What is the matter, Matteo? What has happened?"
"I have terrible news, Francisco. My cousins have both disappeared."
"Disappeared!" Francis repeated in astonishment "How have they disappeared?"
"Their father has just been round to see mine. He is half mad with grief and anger. You know they had gone to spend the day at the Persanis?"
"Yes, yes," Francis exclaimed; "but do go on, Matteo. Tell me all about it, quickly."
"Well, it seems that Polani, for some reason or other, thought he would go and fetch them himself, and at five o'clock he arrived there in his gondola, only to find that they had left two hours before. You were right, Francisco, it was that beldam Castaldi. She went with them there in the morning, and left them there, and was to have come in the gondola for them at six. At three o'clock she arrived, saying that their father had met with a serious accident, having fallen down the steps of one of the bridges and broken his leg, and that he had sent her to fetch them at once.
