Fangen 1 by Marcel Proust

A possessive narrator, consumed by jealousy and the wish to hold onto a lover, keeps her in his home and watches her every movement, alternately interrogating and cherishing her while trying to reconcile his need for control with the fragility of desire; through claustrophobic domestic scenes, surveillance, and introspective digressions about memory, art, and the nature of love, the narrative examines how possession destroys intimacy even as it springs from fear of loss.
