Which Argentine writer wrote the 1940 novel 'The Invention of Morel'?

Argentine writer Adolfo Bioy Casares wrote the 1940 novel The Invention of Morel.

Originally published in Spanish as La invención de Morel, the novel follows a fugitive hiding on a seemingly deserted island. When visitors suddenly appear, he becomes fascinated by a woman named Faustine and tries to understand why the people and events around him seem repetitive and strangely inaccessible.

The mystery centers on Morel’s invention, a machine that records people, voices, and surroundings so completely that its reproductions appear indistinguishable from reality. The book blends speculative fiction, fantasy, philosophical questions about identity, and an atmosphere of psychological suspense.

Bioy Casares was a close friend and collaborator of Jorge Luis Borges, who wrote an influential introduction to the novel. Readers sometimes attribute the book to Borges because of that association, but the author was Bioy Casares. The novel also influenced discussions of Alain Resnais’s 1961 film Last Year at Marienbad, although direct influence has been debated.
