"To the right, Giuseppi, hard!" Francis cried as he glanced over his shoulder.

A sweep with both oars brought the gondola's head, in a moment, almost at right angles to the course that she had been pursuing; and the next sent her dancing on a new line, just as a four-oared gondola swept down upon them, missing their stern by only three or four feet. Had they been less quick in turning, the iron prow would have cut right through their light boat.

Giuseppi burst into a torrent of vituperation at the carelessness of the gondoliers who had so nearly run into them, but Francis silenced him at once.

"Row, Giuseppi. It was done on purpose. It is the gondola the other spoke to."

Their a.s.sailant was turning also, and in a few seconds was in pursuit. Francis understood it now. The gondola they had been following had noticed them, and had informed their friends, waiting off Saint Mark's, of the fact. Intent upon watching the receding boat, he had paid no further attention to the four-oared craft, which had made a turn, and lay waiting in readiness to run them down, should they follow in the track of the other boat.

Francis soon saw that the craft behind them was a fast one, and rowed by men who were first-rate gondoliers. Fast as his own boat was flying through the water, the other gained upon them steadily. He was heading now for the entrance to the Grand Ca.n.a.l, for their pursuer, in the wider sweep he had made in turning, was nearer to the Piazza than they were, and cut off their flight in that direction.

"Keep cool, Giuseppi," he said. "They will be up to us in a minute or two. When their bow is within a yard or two of us, and I say, 'Now!' sweep her head straight round towards the lagoon. We can turn quicker than they can. Then let them gain upon us, and we will then turn again."

The gondola in pursuit came up hand over hand. Francis kept looking over his shoulder, and when he saw its bow gliding up within a few feet of her stern he exclaimed "Now!" and, with a sudden turn, the gondola again swept out seaward.

Their pursuer rushed on for a length or two before she could sweep round, while a volley of imprecations and threats burst from three men who were standing up in her with drawn swords. Francis and Giuseppi were now rowing less strongly, and gaining breath for their next effort. When the gondola again came up to them they swept round to the left, and as their pursuers followed they headed for the Grand Ca.n.a.l.

"Make for the steps of Santa Maria church. We will jump out there and trust to our feet."

The two lads put out all their strength now. They were some three boats' lengths ahead before their pursuers were fairly on their track. They were now rowing for life, for they knew that they could hardly succeed in doubling again, and that the gondola behind them was so well handled, that they could not gain on it at the turnings were they to venture into the narrow channels. It was a question of speed alone, and so hard did they row that the gondola in pursuit gained but slowly on them, and they were still two lengths ahead when they dashed up to the steps of the church.

Simultaneously they sprang on sh.o.r.e, leaped up the steps, and dashed off at the top of their speed, hearing, as they did so, a crash as the gondola ran into their light craft. There was a moment's delay, as the men had to step across their boat to gain the sh.o.r.e, and they were fifty yards ahead before they heard the sound of their pursuers' feet on the stone steps; but they were lightly clad and shoeless, and carried nothing to impede their movements, and they had therefore little fear of being overtaken.

After racing on at the top of their speed for a few minutes, they stopped and listened. The sound of their pursuers' footsteps died away in the distance; and, after taking a few turns to put them off their track, they pursued their way at a more leisurely pace.

"They have smashed the gondola," Giuseppi said with a sob, for he was very proud of the light craft.

"Never mind the gondola," Francis said cheerfully. "If they had smashed a hundred it would not matter."

"But the woman has got away and we have learned nothing," Giuseppi said, surprised at his master's cheerfulness.

"I think we have learned something, Giuseppi. I think we have learned everything. I have no doubt the girls are confined in that hut on San Nicolo. I wonder I never thought of it before; but I made so sure that they would be taken somewhere close to where Mocenigo was staying, that it never occurred to me that they might hide them out there. I ought to have known that that was just the thing they would do, for while the search would be keen among the islets near the land, and the villages there, no one would think of looking for them on the seaward islands.

"I have no doubt they are there now. That woman came ash.o.r.e to report to his friends, and that four-oared boat which has chased us was in waiting off Saint Mark's, to attack any boat that might be following them.

"We will go to Signor Polani at once and tell him what has happened. I suppose it is about one o'clock now, but I have not noticed the hour. It was past eleven before we first met the gondola, and we must have been a good deal more than an hour lying there waiting for them."

A quarter of an hour's walking took them to the palazzo of Polani. They rang twice at the bell at the land entrance, before a face appeared at the little window of the door, and asked who was there.

"I wish to see Signor Polani at once," Francis said.

"The signor retired to rest an hour ago," the man said.

"Never mind that," Francis replied. "I am Francis Hammond, and I have important news to give him."

As soon as the servitor recognized Francis' voice, he unbarred the door.

"Have you news of the ladies?" he asked eagerly.

"I have news which will, I hope, lead to something," Francis replied.

A moment later the voice of Polani himself, who, although he had retired to his room, had not yet gone to sleep, was heard at the top of the grand stairs, inquiring who it was who had come so late; for although men had been arriving all day, with reports from the various islands and villages, he thought that no one would come at this hour unless his news were important.

Francis at once answered:

"It is I, Signor Polani, Francis Hammond. I have news which I think may be of importance, although I may be mistaken. Still, it is certainly news that may lead to something."

The merchant hurried down.

"What is it, Francisco? What have you learned?"

"I have seen the woman Castaldi, and have followed her. I do not know for certain where she was going, for we have been chased by a large gondola, and have narrowly escaped with our lives. Still, I have a clue to their whereabouts."

Francis then related the events of the evening.

"But why did you not run into the boat and give the alarm at once, Francisco? Any gondolas pa.s.sing would have given their a.s.sistance, 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."

"I do not think I would do anything tonight, sir," Francis said. "The gondola that chased us will be on the alert. They cannot, of course, suspect in the slightest that we have any clue to the hiding place of your daughters. Still, they might think that, if we were really pursuing the other gondola, and had recognized the woman Castaldi, we might bring the news to you, and that a stir might be made. They may therefore be watching to see if anything comes of it; and if they saw a bustle and gondolas setting out taking the direction of the island, they might set off and get there first, for it is a very fast craft, and remove your daughters before we reach the hut.

"I should say wait till morning. They may be watching your house now, and if, in an hour or two, they see all is quiet, they will no doubt retire with the belief that all danger is at an end. Then, in the morning, I would embark the men in two or three gondolas, but I would not start from your own steps, for no doubt your house is watched. Let the men go out singly, and embark at a distance from here, and not at the same place. Once out upon the lagoon, they should row quietly towards San Nicolo, keeping a considerable distance apart, the men lying down in the bottom as the boats approach the island, so that if anyone is on watch he will have no suspicion.

"As I am the only one that knows the position of the hut, I will be with you in the first gondola. We will not land near the hut, but pa.s.s by, and land at the other end of the island. The other gondolas will slowly follow us, and land at the same spot. Then three or four men can go along by the sea face, with orders to watch any boats hauled up upon the sh.o.r.e there, and stop any party making down towards them. The rest of us will walk straight to the hut, and, as it lies among sand hills, I hope we shall be able to get quite close to it before our approach is discovered."

"An excellent plan, Francisco, though I am so impatient that the night will seem endless to me; but certainly your plan is the best. Even if the house is watched, and you were seen to enter, if all remains perfectly quiet they will naturally suppose that the news you brought was not considered of sufficient importance to lead to any action. You will, of course, remain here till morning?"

"I cannot do that, sir, though I will return the first thing. There is, lying on my table, a paper with the particulars and names of the persons I saw meet in this hut, and a request to my father that, if I do not return in the morning, he will at once lay this before the council. I place it there every day when I go out, in order that, if I should be seized and carried off by Mocenigo's people, I should have some means of forcing them to let me go.

"Although I know absolutely nothing of the nature of the conspiracy, they will not know how much I am aware of, or what particulars I may have given in the doc.u.ment; and as I could name to them those present, and among them is the envoy of the King of Hungary, now in the city, they would hardly dare harm me, when they knew that if they did so this affair would be brought before the council."

"It was an excellent precaution, Francisco. Why, you are as prudent and thoughtful as you are courageous!"
