His blind and aged father and his gentle sister lay in a noisome dungeon while he enjoyed the free air and the society of her whom he loved. This idea was torture to him.
Chapter 14 · The Creature
Context
The Creature narrates Felix's anguish upon learning that his father and sister have been imprisoned in Paris as punishment for his role in helping the Turk escape, while he himself remains free in Italy with Safie.
Analysis
The sentence structure forces readers to experience Felix's guilt in real time: the first clause piles up images of suffering ('blind,' 'aged,' 'noisome dungeon') while the second presents his own comfort ('free air,' 'society of her whom he loved'), and then the blunt third sentence—'This idea was torture to him'—names the psychological effect. The word 'torture' is deployed as metaphor here, but it puts Felix's mental pain in the same category as his family's physical imprisonment, collapsing the distance between them.
Essay Tip
Support a thesis that Shelley uses the De Lacey plot to show how virtue can trap people as effectively as vice—Felix's moral choice to rescue the Turk becomes the direct cause of his family's ruin, which anticipates Victor's pattern of well-intentioned actions (creating life to defeat death) producing catastrophic unintended consequences.
