A down-on-their-luck married couple take in a quiet, secretive lodger to relieve financial strain, and his odd habits and nocturnal comings and goings soon provoke rumor and fear. Neighbors, a detective acquaintance, and the household itself become increasingly uneasy as suspicion coalesces around the newcomer. The narrative traces the slow erosion of domestic calm, the couple’s moral anxieties, and the corrosive power of gossip, building psychological suspense through atmosphere, small domestic details, and the community’s readiness to believe the worst.
