We stopped in amaze, and Machiavelli, who had spoken, quietly emptied his glass into a bowl beside him.

"What does this mean?" said the cardinal.

"This, your eminence," and Machiavelli held out his hand, on which an opal was flashing a moment before. The stone was still there, in the gold band on his finger; but it was no longer an opal, but something black as jet, devoid of all lustre.

Startled by the movement, D'Amboise bent over the extended fingers, and I followed his example. The red on the cardinal's cheek went out, and his lips paled as he looked at the ring.

"Poison! Heart of Jesus!" he muttered through pale lips.

"Yes," said Machiavelli, slowly, withdrawing his hand, "the ring tells no lies. Diavolo! Was ever so grim a jest? Asking you to tell him if your eminence liked the wine!"

It was too near a matter to be pleasant, and the hideous jest, and the treachery of Alexander, filled me with a hot anger. It had the effect however of pulling me together at once, the sudden presence of death, and the danger, recalling me to myself, for all my thoughts of Angiola. I breathed a prayer of thanks for our escape. It was a good omen. My luck was not yet run out.

D'Amboise sprang to his feet. "By God!" he said, bringing his clenched fist into the palm of his hand, "the Borgia will rue this day; here, give me those glasses." He seized them, and drawing back the curtains flung them out of the window, where they fell into the court outside, breaking to splinters with a little tinkling crash. Then he emptied out the contents of the flagon, and hurled it into the grate where it lay, its fine work crushed and dented, the two emerald eyes of the dragon on the stopper blinking at us wickedly. This outburst made D'Amboise calmer, and it was with more composure that he struck a small gong, and reseated himself at the table. As he did so Burin entered the room.

"We want a clear table," said the cardinal, "remove these things, and hand me that map."

By the time Burin had done this, his eminence showed no further trace of excitement, except that his lips were very firmly set, and there was a slight frown on his forehead as he smoothed out the roll of the map. One corner kept obstinately turning up, and as Machiavelli quietly put his hand on it to keep it in position, he said, "See! The ring is as it was before."
