Suddenly Valcour stood up and faced him.

“Traitor!” he cried, with a passionate gesture, “it is you who have done this! It is you who have led us here only to humiliate us and laugh at us!”

“Your Majesty,” said Paola, without moving his head, “will you kindly protect me from the insults of your servants?”

“Have peace, Valcour!” growled the Emperor. “Senhor Francisco has proved his loyalty, and doubtless shares our chagrin. Come, gentlemen, let us leave this dismal place.”

I followed slowly in the train of the party as it wound its way through the narrow passage and up the iron stairs into the library. My hand-cuffs had been removed when I was brought to open the vault, and an idea came to me to lag behind and try to effect my escape from the house.

But Valcour was waiting for me at the trap door, and called Captain de Souza to guard me. I was taken to the large room on the ground floor, from whence they had brought me, thrust through the doorway, and the key turned upon me.

Piexoto had been taken elsewhere, and I found myself alone.

My thoughts were naturally confused by the amazing discovery we had just made, and I was so engaged in wondering what had become of Dom Miguel and the records that I scarcely looked up when the door opened to admit Francisco Paola.

He had in his hand a small parcel that looked like a box, which he placed upon a table near the open window.

Next he drew a note-book from his pocket, scribbled some lines upon three several leaves, and then, tearing them out, he reached within the box, taking care to lift but a portion of the cover, and busied himself some moments in a way that made me wonder what he could be doing. I had no suspicion of the truth until he carried the box to the window and quickly removed the cover. Then, although his back was toward me, I heard a rapid flutter of wings, followed by a strange silence, and I knew that Paola was following with his eyes the flight of the birds he had liberated.
