A physician-narrator recounts a harrowing episode that blends a conventional crime mystery with parable-like moral and metaphysical inquiry. Presented in three parts, the narrative follows his attempt to record a terrible adventure that has shattered ordinary feeling and left him dwelling in an ambiguous Twilight where sensations, identity, and belief fragment. Through confession, investigation, and reflection on desire, conscience, and the limits of scientific understanding, he seeks to restore a sense of wholeness and to reconcile personal passion with ethical consequence.
