And all on account of the pertinacious ambition of a Portuguese king to rule Spain through an alliance with a Spanish princess--an ambition as pertinaciously foiled by the irony of history. No, they were not without excuse, those ancestors of his who had been left behind clinging to the Church. Could they have been genuine converts, these Marranos, or New Christians? he asked himself. Well, whatever his great-grandfathers had felt, his father's faith had been ardent enough, of that he could not doubt. He recalled the long years of ritual; childish memories of paternal pieties. No, the secret conspiracy had not embraced the Da Costa household. And he would fain believe that his more distant progenitors, too, had not been hypocrites; for aught he knew they had gone over to the Church even before the Expulsion; at any rate he was glad to have no evidence for an ancestry of deceit. None of the Da Costas had been cowards, thank Heaven! And he--he was no coward, he told himself. IV In the morning, though only a few hours of sleep had intervened, the enthusiasm of the night had somewhat subsided. "Whence came the inspiration of Moses?" flew up to his mind almost as soon as he opened his eyes on the sunlit world. He threw open the protrusive casement of his bedroom to the balmy air, tinged with a whiff of salt, and gazed pensively at the white town rambling down towards the shining river.

The secretary rubbed his hands at the sight of the speechful face. "Aha! What new foxes hast thou scented?" The greeting stung like a stab. "None," he replied, with a tremor in his speech and in his limbs. "I did but desire to learn if I am to blame for Dom Diego's arrest." "To blame?" and the secretary looked askance at him. "Say, rather, to praise." "Nay, to blame," repeated Gabriel staunchly. "Mayhap I mistook or misrendered his conversation. 'Tis scant evidence to imprison a man on. I trust ye have found more." "Ay, thou didst but set Frei José on the track. We did not even trouble thee to appear before the Qualifiers." "And he is, indeed, a Jew!" "A Hebrew of Hebrews, by his stiff-neckedness. But 'twas not quite proven; the fox is a cunning beast. Already he hath had the three 'first audiences,' but he will not confess and be made a Penitent. This morning we try other means." "Torture?" said Gabriel, paling. The secretary nodded. "But if he is innocent."
