As long as you stay between these walls, whatever happens must happen on the right or the left of the stove. Saint Denis himself could come in carrying his head in his hands and he would still have to enter on the right, walk between the shelves devoted to French Literature and the table reserved for women readers. And if he doesn’t touch the ground, if he floats ten inches above the floor, his bleeding neck will be just at the level of the third shelf of books. Thus these objects serve at least to fix the limits of probability.
