He took his departure after a few more words and went out by the back door; he then walked in the direction of the Rialto, muffling himself in his great cloak, of which he threw one corner over his shoulder, so that it almost covered his face. He had left his gondola waiting in the narrow canal, and if he chose to come back and take it again, he could reach it without going through the low building in which the Signors of the Night had their office, and the city watch its headquarters.

The Signor had promised to continue the search during three days, and to inform him of any clue he found. Meanwhile, Pignaver thought it would be as well to find the two gentlemen who had been so highly recommended to him, and he hastened to the half-ruined Palazzo Quirini. He went in by a more convenient entrance than the two Bravi had chosen for reasons of their own, but he found Markos where they had found him, still busy with his accounts in the bright little vestibule. When the Senator entered, he had already slipped on the little velvet mask which most Venetians carried about them in the evening, but the Samian either recognised his voice or knew instinctively that his visitor was a person of quality, for he bowed to the ground, rubbed his large hands as if washing them before serving his guest, and answered the Senator's brief salutation in a profoundly obsequious tone.

Pignaver now laid one finger on his lips and spoke in a whisper, asking whether Markos was acquainted with two honest gentlemen named respectively Signor Trombin and Signor Gambardella.

By an almost miraculous coincidence the two honest gentlemen were at that very moment supping within. Markos offered to call them out.

'Unless,' he added, 'your lordship is in need of supper, and will join them.'

The Senator remembered that he had eaten only a few mouthfuls since dinner, and the savoury fumes from the hall further sharpened his appetite.

'The gentlemen are eating together at the little table in the recess,' Markos added, as he detected signs of hesitation. 'You can turn your back to the room, my lord, if you do not wish to be watched.'

Pignaver nodded and followed the host, who at once led the way in. Some of the people who had been supping when the Bravi had entered were gone away, but others had taken their places. The young Florentine and his beautiful guest had disappeared, and their table was occupied by a noisily gay party, of whom more than half wore masks. The two fair Englishmen in velvet were still gravely drinking with their laughing companions, but their eyes were growing rather dull. The serenaders had finished their meal, and were making soft music in their corner, trying over the songs they were going to sing.

'Gentlemen,' said Markos to the Bravi, 'allow me to introduce a highly respectable personage who has business with you, and would like to join you at supper.'

Trombin and Gambardella rose with a courtesy which showed where they had been bred, in spite of their present profession. Though they had been at supper two hours and had done well by a jar of old Samian, they were as cool and steady as when they had sat down, a fact which predisposed Pignaver in their favour.
