Faulkner is astonishing. I wouldn't say he bewitches you but rather he elementalizes you. Just as in As I Lay Dying, I felt that the author's narration has more than one veil. You can distinguish the basic figures of the plot, you can see the actions of the characters, but you lack the details and the motives. At some points, you understand that something dark or dangerous is hidden beneath, but you hope it is something else and not what you imagine from the outline that is distinguishable in the veil.
The fact that you feel the danger beneath the veil/Faulkner's narration but you don't see it, elementalizes you and makes the reading of this book an astonishing experience.
