The thoughtful brown eyes smiled, the fine hands broke the fragment of wax. A gold ring fell out and rolled some little way along the black and purple Eastern rug. The boy dived after it, and presented it to his lordship.

The ring bore an escutcheon, and the Cardinal found graven upon this escutcheon his own arms the Sforza lion and the flower of the quince. Instantly those dark, thoughtful eyes of his grew keen as they flashed upon the page.

“Did you see the device?” he asked, a hint of steel under the silkiness of his voice.

“I saw nothing, my lord—a ring, no more. I did not even look.”

The Cardinal continued to ponder him for a long moment very searchingly.

“Go—bring this man,” he said at last; and the boy departed, soon to reappear; holding aside the tapestry that masked the door to give passage to a man of middle height wrapped in a black cloak, his face under a shower of golden hair, covered from chin to brow by a black visor.

At a sign from the Cardinal the page departed. Then the man, coming forward, let fall his cloak, revealing a rich dress of close-fitting violet silk, sword and dagger hanging from his jewelled girdle; he plucked away the mask, and disclosed the handsome, weak face of Giovanni Sforza, Lord of Pesaro and Cotignola, the discarded husband of Madonna Lucrezia, Pope Alexander's daughter.

The Cardinal considered his nephew gravely, without surprise. He had expected at first no more than a messenger from the owner of that ring. But at sight of his figure and long, fair hair he had recognized Giovanni before the latter had removed his mask.

“I have always accounted you something mad,” said the Cardinal softly. “But never mad enough for this. What brings you to Rome?”

“Necessity, my lord,” replied the young tyrant. “The need to defend my honour, which is about to be destroyed.”
