'Am not I also a free woman? Did I not yesterday visit the church of the blessed Petronilla, and might I not, if so I had willed, have escaped instead of returning to the city?'

'What has this to do with the matter?' demanded Basil.

'Child! child!' cried the other, as if with boundless contempt. 'You ask that, knowing why this Veranilda is sought by the Greeks? Were they truly still in search of her, and were you, were I, suspected of keeping her hidden, do you suppose we should be free, and not rather locked as close as any prison in Rome could hold us?'

The listener stood mute. So vehement was Petronilla's speech, and so convincing, thus delivered, seemed her argument, that Basil felt his heart sink. Had she, then, outwitted him? Was he really playing the part of a simpleton, at whom people laughed? He remembered the seeming indifference of Bessas touching Veranilda at the second interview, natural enough if the maiden had already passed into the Greek's hands. Two days ago Marcian had told him that Petronilla must needs be aware of Veranilda's importance, seeing that it was now common knowledge in Roman society. But a thought flashed into his mind, and he lifted up his head again.

'This is not true!' he exclaimed. 'If Bessas had found her, I should have known it.'

'Pray, how? Does your foolish little lordship imagine that Bessas must needs have told you all he has done?'

'Bessas? no,' he answered, his eyes burning with hatred as they searched her face. 'But I have other means of learning the truth. You try vainly to deceive me.'

'As you will, good nephew,' said the lady, as if indulgently. 'Believe as you list, and talk on, for you entertain me.'

'One thing I have to say,' pursued Basil, 'which you will perhaps find less amusing.' He had lost control of himself, and spoke in a low tone of fierce menace, all his body quivering. 'If I learn that Veranilda is in the hands of the Greeks, and that you delivered her to them—by the God above us, your life shall pay for it.'

Petronilla's face hardened till its cruel sternness outdid any expression of hatred possible to Basil's features.
