This time Monsieur D'Ogeron laughed outright. "Mon prince," he said, "you have small idea of the completeness of my defences. Were it my will, I could have you safe in an unbreakable prison before another second had passed."

"I do not take you, Monsieur."

The Governor rubbed his hands appreciatively. "My dungeons," he said, "are beneath this chamber, rock-hewn, deep and vastly unpleasant. The floor on which we stand is so ingeniously contrived that at will any portion of it can be made to give way, and drop an inconvenient person into safety below. I have a trusty knave at hand attending on the bolts."

"Who is probably asleep, like your other fellow."

The Governor frowned. "I do not think so, your Highness. But we will soon see. I might call your attention to the embrasure of the window behind you. In case other foothold goes, it will afford you a scanty seat." Then, lifting his voice, he cried loudly for "Jean Paul!"

On the instant a great flap of the floor beneath the Prince's feet swung downwards, and had not Rupert been warned, there is not a doubt but that he would have been shot helplessly through the gap into the prison beneath. But as it was, with a scramble he reached the ledge of the window, and sat there cursing aloud at Tortuga and all the monkeys and the monkeyish tricks it contained.

It was plain the Governor wished to laugh—for when half drunk he was a merry enough ruffian—but he saw the Prince's rage and choked back his mirth. "Nay, your Highness," he said, "you brought it on yourself by doubting whether my man Jean Paul stayed awake. I have known all my fellows long. Alphonse drowses sometimes when the heat is great and he has liquor in him, but, Jean Paul never. That is why I have set Jean Paul over the strings which govern the bolts, and he has never failed me, and never pulled the wrong string. And it is no light business to keep the tally of them either, for there is a separate string for every square fathom of the floor."

"You keep a most delicate care of your health, Monsieur."

"It is necessary," said the Governor, with a shrug. "I have some queer callers. Men in these seas want many things, and when they cannot get them for the asking, they are not averse to using violence if they think it will succeed. I dare lay a wager, mon prince, that if you saw those late officers of yours, which Monsieur Cromwell sent me, standing by the harbour side, you would not think twice about clapping them on board and carrying them to sea without a piastre of recompense?"

"It would be my bare duty to gentlemen who have been my very faithful comrades."
