"Yes," replied Gonsalvo steadily; "I mean murder--as the shepherd does who strangles the wolf with his paw on the lamb."

"Oh, think--"

"I have thought of everything. And mark me, Don Carlos, I have but one regret. It is that my weapon deals an instantaneous death. Such revenge is poor and flavourless after all. I have heard of poisons whose least drop, mingling with the blood, ensures a slow agonizing death--time to learn what torture means, and to drain to the dregs the cup filled for others--to curse God and man ere he dies. For a phial of such, wherewith to anoint my blade, I would sell my soul to-night."

"O Gonsalvo, this is horrible! They are wild, wicked words you speak. Pray God to pardon you!"

"I adjure him by his justice to prosper me," said Gonsalvo, raising his head defiantly.

"He will not prosper you. And do you dream that such a mad achievement (suppose you even succeed in it) will open prison-doors and set captives free? Alas! alas! that we are not at the mercy of a tyrant's will. For tyrants, the worst of them, sometimes relent; and--they are mortal. That which is crushing us is not a living being, an organism with nerves, and brain, and blood. It is a system, a THING, a terrible engine, that moves on in its resistless way, cold and lifeless, without will or feeling. Strong as adamant, it kills, tortures, destroys; obeying laws far away out of our sight. Were Valdez and Munebrãga, and all the Board of Inquisitors, dead corpses by the morning light, not a single dungeon in the Triana would open its pitiless gate."

"I do not believe that," replied Gonsalvo, rather more quietly. "Surely there must be some confusion, of which advantage may be taken by friends of the prisoners. This, indeed, is the motive which now induces me to confide in you. You may know those who, if they had the chance, could strike a shrewd blow to save their dearest on earth from torture and death."

But Gonsalvo read no answer in the sorrowful face of Carlos to the searching look of inquiry with which he said this. After a silence he went on,--

"Suppose the worst, however. The Holy Office sorely needs a little blood-letting, and will be much the better for it. Whoever succeeds, Munebrãga will have my dagger flashing in his eyes, and will take care how he deals with his prisoners, and whom he arrests."

"I implore you to think of yourself," said Carlos.
