The general opinion, among the boatmen, was that some lady must have been carried off, and that her friends were seeking for a clue as to the spot to which she had been taken.
One evening Francis had been strolling on the Piazza with Matteo, and had remained out later than he had done since the night of his last visit to San Nicolo. He took his seat in the gondola, and when Giuseppi asked him if he would go home, said he would first take a turn or two on the Grand Canal as the night was close and sultry.
There was no moon now, and most of the gondolas carried torches. Giuseppi was paddling quietly, when a pair-oared gondola shot past them, and by the light of the torch it carried, Francis recognized the ladies sitting in it to be Maria and Giulia Polani with their duenna; two armed retainers sat behind them. They were, Francis supposed, returning from spending the evening at the house of some of their friends. There were but few boats now passing along the canal.
Polani's gondola was a considerable distance ahead, when Francis heard a sudden shout of, "Mind where you are going!"
Then there was a crash of two gondolas striking each other, followed by an outburst of shouts and cries of alarm, with, Francis thought, the clash of swords.
"Row, Giuseppi!" he exclaimed, leaping from his seat and catching up the other oar; and with swift and powerful strokes the two lads drove the gondola towards the scene of what was either an accident, or an attempt at crime.
They had no doubt which it was when they arrived at the spot. A four-oared gondola lay alongside that of the Polanis, and the gondoliers with their oars, and the two retainers with their swords, had offered a stout resistance to an armed party who were trying to board her from the other craft, but their resistance was well nigh over by the time Francis brought his gondola alongside.
One of the retainers had fallen with a sword thrust through his body, and a gondolier had been knocked overboard by a blow from an oar. The two girls were standing up screaming, and the surviving retainer was being borne backwards by three or four armed men, who were slashing furiously at him.
"Quick, ladies, jump into my boat!" Francis exclaimed as he came alongside, and, leaning over, he dragged them one after the other into his boat, just as their last defender fell.
With a fierce oath the leader of the assailants was about to spring into the gondola, when Francis, snatching up his oar, smote him with all his strength on the head as he was in the act of springing, and he fell with a heavy splash into the water between the boats.
