The Horla

by Guy de Maupassant · 1887

The Horla is a seminal work of psychological horror written as a private diary. It chronicles the descent of an affluent Normandy gentleman into paranoia and madness as he becomes convinced that an invisible, malevolent entity—the Horla—is haunting his home, draining his vitality, and controlling his will. The narrative blurs the line between supernatural intrusion and internal mental collapse, reflecting the author's own struggles with illness and the anxieties of late 19th-century France.
