The Horla is presented as a series of diary entries written by an educated, increasingly tormented gentleman living in solitude on his country estate near Rouen. His initial feelings of malaise and feverish restlessness soon give way to a terrifying certainty: he is not alone. He is being slowly, subtly drained of his life force and sanity by an invisible, parasitic entity, a creature he names the Horla. Through meticulous observation and escalating terror, the narrator tracks the Horla's movements, proving its existence and realizing that this unseen being represents a new, superior form of life destined to dominate and consume humanity.

From the mind of Guy de Maupassant, one of France's most celebrated literary masters, comes a seminal work of psychological horror and cosmic dread that redefined the supernatural genre.

This gripping story is a masterful blend of psychological realism and cosmic horror, influencing generations of writers from H. P. Lovecraft onward. It is essential reading for fans of classic supernatural fiction and tales of deep, unrelenting dread.
