The final volume continues the tangled domestic and legal entanglements surrounding the central characters, alternating intimate drawing-room scenes with moments of investigation and travel. Geoffrey broods over thwarted desires during social entertainments while Lucille endures disturbing dreams that prompt a frank confession and the formation of a new friendship. The protagonist seeks clarification and justice, at one point journeying to Rouen as old acquaintances and secrets resurface. Gradually buried truths come to light, misunderstandings are confronted, and the narrative closes with moral reckonings, personal sacrifices, and an epilogue that resolves the main characters' fates.
