Le Horla

The narrator keeps a diary that begins with peaceful rural contentment but gradually records a creeping illness: fever, sleepless nights, paralytic nocturnal suffocation, and an intensifying sense of being watched by an invisible presence. Medical remedies and brief travel bring only temporary relief as obsession grows and daily life deteriorates. Detailed entries trace attempts to observe, understand, and drive away the unseen force, weighing psychological explanation against supernatural invasion. The account becomes a tense confessional of mounting fear and escalating measures taken to confront an indiscernible antagonist, leaving the boundary between madness and external agency unresolved.
