Falier stammered an excuse.

"We have not your eyes, Excellency; we cannot work miracles—but at least we can try to protect you from the hand of the assassin. Name this woman to me, and she shall not live when midnight strikes."

Frà Giovanni rose from his chair and put his hand gently upon the other's shoulder.

"You say, Excellency—?"

"That the city is in danger as never she was before in her history."

"And your own life?"

"Shall be given for Venice if necessary. Listen to this: you seek to be of service to me. Have you any plan?"
