"Don't frighten her away," Francis said, laughing. "She is the one pleasant thing I have in the day to look at."

After some more talk the man retired, and Francis examined his prize. It was a thin blade of fine steel, and he at once hid it in the earth which formed the floor of the hut.

An hour later the guard opened the door suddenly. It was now dusk, and Francis was sitting quietly in a corner.

"Bring a light, Thomaso," the guard shouted to his comrade outside. "It is getting dark in here."

The other brought a torch, and they carefully examined the floor of the cell.

"What is it that you are searching for?" Francis asked.

"I have dropped my dagger somewhere," the man replied. "I can't think how it fell out."

"When did you see it last?"

"Not since dinner time. I know I had it then. I thought possibly I might have dropped it here, and a dagger is not the sort of plaything one cares about giving to prisoners."

"Chained as I am," Francis said, "a dagger would not be a formidable weapon in my hands."

"No," the man agreed. "It would be useless to you, unless you wanted to stick it into your own ribs."

"I should have to sit down to be able to do even that."

"That is so, lad. It is not for me to question what the captain says, I just do as I am told. But I own it does seem hard, keeping a young fellow like you chained up as if you were a wild beast. If he had got Pisani or Zeno as a prisoner, and wanted to make doubly sure that they would not escape, it would be all well enough, but for a lad like you, with one man always at the door, and the window barred so that a lion couldn't break through, I do think it hard to keep you chained like this; and the worst of it is, we are going to have to stop here to look after you till the captain gets back, and that may be three weeks or a month, who knows!"

"Why don't you keep your mouth shut, Philippo?" the other man growled. "It's always talk, talk with you. We are chosen because the captain can rely upon us."

"He can rely upon anyone," Philippo retorted, "who knows that he will get his throat cut if he fails in his duty."

"Well, come along," the other said, "I don't want to be staying here all night. Your dagger isn't here, that's certain, and as I am off guard at present, I want to be going."

As soon as he was left alone, Francis unearthed the dagger, feeling sure that no fresh visit would be made him that evening. As he had hoped, his first attempt showed him that the iron of the rivet was soft, and the keen dagger at once notched off a small piece of the burred end. Again and again he tried, and each time a small piece of metal flew off. After each cut he examined the edge of the dagger, but it was well tempered, and seemed entirely unaffected.

He now felt certain that, with patience, he should be able to cut off the projecting edges of the rivets, and so be able to free his hands. He, therefore, now examined the fastenings at the ankles. These were more heavy, and on trying them, the iron of the rivet appeared to be much harder than that which kept the manacles together. It was, however, now too dark to see what he was doing, and concealing the dagger again, he lay down with a lighter heart than he had from the moment of his capture.

Even if he found that the lower fastenings of the chain defied all his efforts, he could cut the rivets at the wrists, and so free one end of each chain. He could then tie the chains round his legs, and their weight would not be sufficient to prevent his walking.

Chapter 13: The Pirates' Raid.

As soon as it was daylight next morning, Francis was up and at work. His experiments of the evening before were at once confirmed. Three or four hours' work would enable him to free his wrists, but he could make no impression on the rivets at his ankles. After a few trials he gave this up as hopeless, for he was afraid, if he continued, he would blunt the edge of the dagger.

For an hour he sat still, thinking, and at last an idea occurred to him. Iron could be ground by rubbing it upon stone, and if he could not cut off the burr of the rivet with the dagger, he might perhaps be able to wear it down, by rubbing it with a stone.

He at once turned to the walls of his cell. These were not built of the unbaked clay so largely used for houses of the poorer cla.s.s in Northern Egypt, but had evidently been constructed either as a prison, or more probably as a strong room where some merchant kept valuable goods. It was therefore constructed of blocks of hard stone.

It seemed to Francis that this was sandstone, and to test its quality, he sat down in the corner where the guard had, the night before, placed his supply of food and water. First he moistened a portion of the wall, then he took up a link of his chain, and rubbed for some time against it. At last, to his satisfaction, a bright patch showed that the stone was capable of wearing away iron. But in vain did he try to twist his legs so as to rub the rivet against the wall, and he gave up the attempt as impossible.

It was clear, then, that he must have a bit of the stone to rub with. He at once began to dig with the dagger in the earth at the foot of the wall, to see if he could find any such pieces. For a long time he came across no chips, even of the smallest size. As he worked, he was most careful to stamp down the earth which he had moved, scattering over it the sand, of which there was an abundance in the corners of the room, to obliterate all traces of his work.

When breakfast time approached he ceased for a while, but after the meal had been taken, he recommenced the task. He met with little success till he reached the door, but here he was more fortunate. A short distance below the surface were a number of pieces of stone of various sizes, which, he had no doubt, had been cut from the blocks to allow for the fixing of the lintel and doorpost. He chose half a dozen pieces of the handiest sizes, each having a flat surface. Then replacing the earth carefully, he took one of the pieces in his hand, and moistening it with water, set to work.

He made little progress. Still the stone did wear the iron, and he felt sure that, by perseverance, he should succeed in wearing off the burrs. All day he worked without intermission, holding a rag wrapped round the stone to deaden the sound. He worked till his fingers ached so that he could no longer hold it, then rested for an hour or two, and resumed his work. When his guard brought his dinner he asked him when the galley was to sail again.

"It was to have gone today," the man said, "but the captain has been laid up with fever. He has a leech from Tunis attending him, and, weak as he is, he is so bent on going that he would have had himself carried on board the ship, had not the leech said that, in that case, he would not answer for his life, as in the state his blood is in, his wounds would a.s.suredly mortify did he not remain perfectly quiet. So he has agreed to delay for three days."

Francis was unable to work with the stone at night, for in the stillness the sound might be heard; but for some hours he hacked away with the dagger at the rivets on his manacles. The next morning he was at work as soon as the chirrup of the cicadas began, as these, he knew, would completely deaden any sound he might make. By nighttime the rivet ends on the irons round his ankles were worn so thin, that he felt sure that another hour's work would bring them level with the iron, and before he went to sleep the rivets on the wrist were in the same condition.

He learned from his guard, next morning, that the captain was better, that he was to be taken on board in the cool of the evening, and that the vessel would start as soon as the breeze sprang up in the morning. In the afternoon his two guards entered, and bade him follow them. He was conducted to the princ.i.p.al house in the village, and into a room where Ruggiero Mocenigo was lying on a couch.

"I have sent for you," Ruggiero said, "to tell you that I have not forgotten you. My vengeance has been delayed from no fault of mine, but it will be all the sweeter when it comes. I am going to fetch Polani's daughters. I have heard that, since you thrust yourself between me and them, you have been a familiar in the house, that Polani treats you as a member of the family, and that you are in high favour with his daughters. I have kept myself informed of what happened in Venice, and I have noted each of these things down in the account of what I owe you. I am going to fetch Polani's daughters here, and to make Maria my wife, and then I will show her how I treat those who cross my path. It will be a lesson to her, as well as for you. You shall wish yourself dead a thousand times before death comes to you."

"I always knew that you were a villain, Ruggiero Mocenigo," Francis said quietly, "although I hardly thought that a man who had once the honour of being a n.o.ble of Venice, would sink to become a pirate and renegade. You may carry Maria Polani off, but you will never succeed through her in obtaining a portion of her father's fortune, for I know that, the first moment her hands are free, she will stab herself to the heart, rather than remain in the power of such a wretch."

Ruggiero s.n.a.t.c.hed up a dagger from a table by his couch as Francis was speaking, but dropped it again.

"Fool," he said. "Am I not going to carry off the two girls? and do you not see that it will tame Maria's spirit effectually, when she knows that if she lays hands on herself, she will but shift the honour of being my wife from herself to her sister?"

As the laugh of antic.i.p.ated triumph rang in Francis's ears, the latter, in his fury, made a spring forward to throw himself upon the villain, but he had forgotten his chains, and fell headlong on to the floor.

"Guards," Ruggiero shouted, "take this fellow away, and I charge you watch over him securely, and remember that your lives shall answer for his escape."

"There is no need for threats, signor," Philippo said. "You can rely on our vigilance, though, as far as I see, if he had but a child to watch him he would be safe in that cell of his, fettered as he is."

Ruggiero waved his hand impatiently, and the two men withdrew with their prisoner.

"If it were not that I have not touched my share of the booty of our last trip," Philippo said as they left the house, "I would not serve him another day. As it is, as soon as the galley returns, and we get our shares of the money, and of the sum he has promised if this expedition of his is successful, I will be off. I have had enough of this. It is bad enough to be consorting with Moors, without being abused and threatened as if one was a dog."

As soon as he was alone again, Francis set to work, and by the afternoon the ends of the four rivets were worn down level with the iron, and it needed but a pressure to make the rings spring open. Then he waited for the evening before freeing himself, as by some chance he might again be visited, and even if free before nightfall he could not leave the house.

Philippo was later than usual in bringing him his meal, and Francis heard angry words pa.s.sing between him and his comrade, because he had not returned to relieve him sooner.

"Is everything ready for the start?" Francis asked the man as he entered.

"Yes, the crew are all on board. The boat is to be on sh.o.r.e for the captain at nine o'clock, and as there is a little breeze blowing, I expect they will get up sail and start at once."

After a few minutes' talk the man left, and Francis waited until it became almost dark, then he inserted the dagger between the irons at the point of junction. At the first wrench they flew apart, and his left hand was free. A few minutes' more work and the chains lay on the ground.

Taking them up, he rattled them together loudly. In a minute he heard the guard outside move and come to the door, then the key was inserted in the lock and the door opened.

"What on earth are you doing now?" Philippo asked as he entered.

Francis was standing close to the door, so that as his guard entered he had his back to him, and before the question was finished he sprang upon him, throwing him headlong to the ground with the shock, and before the astonished man could speak he was kneeling upon him, with the point of the dagger at his throat.

"If you make a sound, or utter a cry," he exclaimed, "I will drive this dagger into your throat."
