Zicci Book II by Edward Bulwer-lytton

It was the first faint and gradual break of the summer dawn; and two men stood in a balcony overhanging a garden fragrant with the scents of the awakening flowers. The stars had not left the sky, the birds were yet silent on the boughs; all was still, hushed, and tranquil. But how different the tranquillity of reviving day from the solemn repose of night.

In the music of silence there are a thousand variations. These men, who alone seemed awake in Naples, were Zicci and the mysterious stranger, who had but an hour or two ago startled the Prince di -- in his voluptuous palace.
