Beckett's trilogy

There is something behind the old man looking for his dead mother through a wasted land. (Molloy) There's the man who was hired to find that man, who made up the story of the original man and hired himself. (Moran) But there’s something behind that. There’s the man who is alone in a room in a mental institution who made up the idea of the hired man. (Malone) But there is something behind that. There's the man living in an urn without legs, without arms, who created the man alone in the room in the mental institution with his words. (Mahood) Still, there is something behind that. There is a quivering ear that hears movement and an eye that sees nothing but grayness. (Worm)
