“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 noble 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 snatched 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 anticipated 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 passing 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 shore 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.
