It now appeared that the marquis was poisoned by the vengeance of the woman to whom he had resigned his conscience. The consternation and distress of Ferdinand cannot easily be conceived: he hastened back to his father's chamber, but determined to conceal the dreadful catastrophe of Maria de Vellorno. This precaution, however, was useless; for the servants, in the consternation of terror, had revealed it, and the marquis had fainted. Returning pains recalled his senses, and the agonies he suffered were too shocking for the beholders. Medical endeavours were applied, but the poison was too powerful for antidote. The marquis's pains at length subsided; the poison had exhausted most of its rage, and he became tolerably easy. He waved his hand for the attendants to leave the room; and beckoning to Ferdinand, whose senses were almost stunned by this accumulation of horror, bade him sit down beside him. 'The hand of death is now upon me,' said he; 'I would employ these last moments in revealing a deed, which is more dreadful to me than all the bodily agonies I suffer. It will be some relief to me to discover it.' Ferdinand grasped the hand of the marquis in speechless terror. 'The retribution of heaven is upon me,' resumed the marquis. 'My punishment is the immediate consequence of my guilt. Heaven has made that woman the instrument of its justice, whom I made the instrument of my crimes;----that woman, for whose sake I forgot conscience, and braved vice--for whom I imprisoned an innocent wife, and afterwards murdered her.' At these words every nerve of Ferdinand thrilled; he let go the marquis's hand and started back. 'Look not so fiercely on me,' said the marquis, in a hollow voice; 'your eyes strike death to my soul; my conscience needs not this additional pang.'--'My mother!' exclaimed Ferdinand--'my mother! Speak, tell me.'--'I have no breath,' said the marquis. 'Oh!--Take these keys--the south tower--the trapdoor.--'Tis possible--Oh!--'
