The bells of the Chapel of St. Mark were striking the hour of eight o'clock when, Frà Giovanni stepped from his gondola, and crossed the great square toward that labyrinth of narrow streets and winding alleys they call the Merceria.

The Piazza itself was then ablaze with the light of countless lamps; dainty lanterns, colored as the rainbow, swayed to the soft breeze between the arches of the colonnade. Nobles were seated at the doors of the splendid cafés; the music of stringed instruments mingled with the louder, sweeter music of the bells; women, whose jewels were as sprays of flame, many-hued and dazzling, hung timidly upon the arms of lovers; gallants swaggered in costly velvets and silks which were the spoil of the generous East; even cassocked priests and monks in their sombre habits passed to and fro amidst that glittering throng, come out to herald the glory of a summer's night.

And clear and round, lifting themselves up through the blue haze to the silent world of stars above, were the domes and cupolas of the great chapel itself—the chapel which, through seven centuries, had been the city's witness to the God who had made her great, and who would uphold her still before the nations.

The priest passed through the crowd swiftly, seeming to look neither to the right nor to the left. The brown habit of the Capuchins was his dress, and his cowl was drawn so well over his head that only his eyes were visible—those eyes which stand out so strangely in the many portraits which are still the proud possession of Venice. Though he knew well that an assassin waited for him in the purlieus of the church of San Salvatore, his step was quick and brisk; he walked as a man who goes willingly to a rendezvous, and anticipates its climax with pleasure. When he had left the great square with its blaze of lanterns and its babel of tongues, and had begun to thread the narrow streets by which he would reach the bridge of the Rialto, a smile played for a moment about his determined mouth, and he drew his capuce still closer over his ears.

"So it is Rocca whom they send—Rocca, the poltroon! Surely there is the hand of God in this."

He raised his eyes for a moment to the starlit heaven, and then continued his brisk walk. His way lay through winding alleys; over bridges so narrow that two men could not pass abreast; through passages where rogues lurked, and repulsive faces were thrust grinning into his own. But he knew the city as one who had lived there all his life; and for the others, the thieves and scum of Venice, he had no thought. Not until he came out before the church of Santa Maria Formosa did he once halt or look behind him. The mystery of the night was a joy to him. Even in the shadow of the church, his rest was but for a moment; and, as he rested, the meaning smile hovered again upon his wan face.

"The play begins," he muttered, while he loosened slightly the girdle of his habit and thrust his right hand inside it; "the God of Venice give me courage."

A man was following him now—he was sure of it. He had seen him as he turned to cross the bridge which would set him on the way to the church of San Salvatore—a short, squat man, masked and dressed from head to foot in black. Quick as the movements of the fellow were, dexterous his dives into porches and the patches of shadow which the eaves cast, the priest's trained eye followed his every turn, numbered, as it were, the very steps he took. And the smile upon Frà Giovanni's face was fitful no more. He walked as a man who has a great jest for his company.

"Rocca the fool, and alone! They pay me a poor compliment, those new friends of mine; but we shall repay, and the debt will be heavy."

He withdrew his hand from his habit, where it had rested upon the hilt of a dagger, for he knew that he had no need of any weapon. His gait was quick and careless; he stopped often to peer into some windowless shop where a sickly lamp burned before the picture of a saint; and wares, which had not tempted a dead generation, appealed unavailingly to a living one. The idea that his very merriment might cost him his life never entered his head. He played with the assassin as a cat with a mouse, now tempting him to approach, now turning suddenly, and sending him helter-skelter into the door of a shop or the shadow of a bridge. He was sure of his man, and that certainty was a delight to him.
