“You fill me with alarm, my good Gonzaga,” she answered him, though smiling.

“Alas it has fallen to my unfortunate lot to do more than that. I have made the discovery of as foul a piece of treachery here in your fortress as ever traitor hatched.”

She looked at him more seriously now. The vehemence of his tone, and the suggestion of sorrow that ran through it and gave it so frank an accent, commanded her attention.

“Treachery!” she echoed, in a low voice, her eyes dilating. “And from whom?”

He hesitated a moment, then waving his hand:

“Will you not sit, Madonna?” he suggested nervously.

Mechanically she seated herself at the table, her eyes ever on his face, alarm spreading in her heart, born of suspense.

“Be seated too,” she bade him, “and tell me.”

He drew up a chair, sat down opposite to her, and taking a deep breath: “Heard you ever of the Count of Aquila?” he inquired.

“It were odd if I had not. The most valiant knight in Italy, fame dubs him.”
