"But why did you not run into the boat and give the alarm at once, Francisco? Any gondolas passing would have given their assistance, when you declared who she was, for the affair is the talk of the city. If that woman were in our power we should soon find means to make her speak."
"Yes, signor; but the moment she was known to be in your power, you may be sure that they would remove your daughters from the place where they have been hiding them. I thought, therefore, the best plan would be to track them. No doubt we should have succeeded in doing so, had it not been for the attack upon us by another gondola."
"You are right, no doubt, Francisco. Still, it is unfortunate, for I do not see that we are now any nearer than we were before, except that we know that this woman is in the habit of coming into the city."
"I think we are nearer, sir, for I had an adventure some time ago that may afford a clue to their hiding place."
He then told the merchant how he had, one evening, taken a man out to San Nicolo, and had discovered that a hut in that island was used as a meeting place by various persons, among whom was Ruggiero Mocenigo.
"I might have thought of the place before, signor; but, in fact, it never entered my mind. From the first, we considered it so certain that the men who carried off your daughters would take them to some hiding place where Mocenigo could speedily join them, that San Nicolo never entered my mind. I own that it was very stupid, for it seems now to me that the natural thing for them to do, would be to take them in the very opposite direction to that in which the search for them would be made."
The story had been frequently interrupted by exclamations of surprise by Polani. At its conclusion, he laid his hand on Francis' shoulder.
"My dear boy," he said, "How can I thank you! You seem to me to be born to be the preserver of my daughters. I cannot doubt that your suspicion is correct, and that they are confined in this hut at San Nicolo. How fortunate that you did not denounce this conspiracy--for conspiracy no doubt it is--that you discovered, for, had you done so, some other place would have been selected for the girls' prison."
"I would not be too sanguine, sir. The girls may not be in this hut, still we may come on some clue there which may lead us to them. If not, we will search the islands on that side as closely as we have done those on the mainland."
"Now, shall I send for the gondoliers and set out at once? There are ten or twelve men in the house, and it is hardly likely that they will place a guard over them of anything like this strength, as of course they will be anxious to avoid observation by the islanders."
