And all at once, as though his brain were restored by the freshness of the morning, he grasped the thought which had eluded him. Marcian's treachery was no new thing: twice he had been warned against his seeming friend, by Petronilla and by Bessas, and in his folly he had scorned the accusation which time had now so bitterly justified. Forgotten, utterly forgotten, until this moment; yet how blinded he must have been by his faith in Marcian's loyalty not to have reflected upon many circumstances prompting suspicion. Marcian had perhaps been false to him from the very day of Veranilda's disappearance, and how far did his perfidy extend? Had he merely known where she was concealed, or had he seen her, spoken with her, wooed her all along? He had won her; so much was plain; and he could scarce have done so during the brief journey to his villa. O villainous Marcian! O fickle, wanton Veranilda! So distinct before his fiery imagination shone the image of those two laughing together, walking alone (as Sagaris had reported), that all reasoning, such as a calmer man might have entertained, was utterly forbidden. Not a doubt crossed his mind. And in his heart was no desire but of vengeance. At length he drew near to Arpinum. Avoiding the town, he questioned a peasant at work in the fields, and learnt his way to the island. Just as he came within view of the eastward waterfall, a girl was crossing the bridge, away from the villa. Basil drew rein, bidding his men do likewise, and let the girl, who had a bundle on her head, draw near. At sight of the horsemen, of whom she was not aware till close by them, the maid uttered a cry of alarm, and would have run back but Basil intercepted her, jumped from his horse, and bade her have no fear, as he only wished to ask a harmless question. Easily he learnt that Marcian was at the villa, that he had arrived a few days ago, and that with him had come a lady. 'What is that lady's name?' he inquired. The girl did not know. Only one or two of the slaves, she said, had seen her; she was said to be beautiful, with long yellow hair. 'She never goes out?' asked Basil. The reply was that, only this morning, she had walked in the wood--the wood just across the bridge--with Marcian. Basil sprang on to his horse, beckoned his troop, and rode forward. CHAPTER XXII DOOM
