"My lord——"

Ligozzi put his hand upon his master's arm.

"My lord——"

Mastino raised his head and looked at him; his face was distorted, his eyes unnaturally bright.

"Give them their answer, my lord," said Ligozzi. "Every moment gives them a triumph. Send it now."

"Now," cried Mastino, hoarsely. "They gave me till to-night—surely, Ligozzi, they gave me till to-night."

"Thou dost not need until to-night, my lord. Visconti asked thy honor."

"And offered me," said Della Scala slowly, "Isotta."

Ligozzi looked at him horror-struck; an awful thought was breaking on him.

The eyes of the two men met; Ligozzi's was steady, but Mastino's flinched.
