'Is this to bury misunderstanding?' she cried low. 'O, I would I were Duchess of Milan.'

'More impossible things might happen,' he said thickly, for all his self-control.

She stared at him fascinated a moment; then swiftly advanced again.

'Let me keep the ring,' she urged hoarsely. 'I could set something against it—some knowledge—some information.'

He had mastered himself in the interval; and now stood pondering upon her and fondling his chin.

'Yes?' he murmured. 'But it must be something to be worth.'

She hesitated; then spoke out:—

'A plot to kill the Duke—no more.'

The two stared at one another. She could see a pulse moving in his throat; but when at last he spoke, it was without emotion.
