“The secret is not your own, sir,” I ventured to say.

“True,” he acknowledged, flushing deeply, “the secret is not my own. It belongs to the Cause. And its discovery would jeopardize the revolution itself. For this reason I shall keep Izabel with me, where, admitting she has the inclination to betray us, she will not have the power.”

After this night he did not extinguish the light when we entered the vault, evidently having decided to trust me fully; but he took pains to secure the trap in the study floor so that no one could follow us. After watching him apply the key several times I became confident that I could find the right indentation without trouble should the occasion ever arise for me to unlock the vault unaided.

Days passed by, and Madam Izabel remained as quiet and reserved as if she had indeed abandoned any further curiosity concerning the secret vault. As for my fellow-rebel, the Senhorita Lesba, I rode and chatted with her in the firm conviction that here, at least, was one secret connected with the revolution of which she was ignorant.

CHAPTER VII
GENERAL FONSECA

One evening, as I entered Dom Miguel’s library, I found myself face to face with a strange visitor. He did not wear a mask, as did so many of the conspirators, even in the chief’s presence; but a long black cloak swept in many folds from his neck to his feet.

My first thought was to marvel at his size, for he was considerably above six feet in height and finely proportioned, so that his presence fairly dominated us and made the furnishings of the room in which he stood seem small and insignificant.

As I entered, he stood with his back to the fireplace confronting Dom Miguel, whose face wore a sad and tired expression. I immediately turned to withdraw, but a gesture from the stranger arrested me.

“Robert,” said Dom Miguel, “I present you to General Manuel Deodoro da Fonseca.”

I bowed profoundly. General Fonseca was not only a commander of the Emperor’s royal army, but Chief Marshal of the forces of the Revolutionary party. I had never seen the great man before, as his duties required his constant presence at the capital; but no figure loomed larger than his in the affairs of the conspiracy.
