Le Passe-Muraille is a notable work by French author Marcel Aymé, first published in 1943. The title translates to "The Man Who Walked Through Walls" in English, and it is part of a collection of short stories that blend elements of magic realism with humor and social commentary.

The central story follows Dutilleul, a man living in Montmartre, who discovers he has the extraordinary ability to pass through walls. Initially, he does not take advantage of this power, leading a mundane life. However, after consulting a doctor who prescribes medication for his condition, Dutilleul inadvertently finds himself trapped within a wall due to a misunderstanding regarding the pills he took. This twist highlights themes of isolation and the consequences of one's choices, culminating in Dutilleul's tragic fate of being permanently stuck in the wall.
