In the detective story, as in its mirror image, the Quest for the Grail, maps (the ritual of space) and timetables (the ritual of time) are desirable. Nature should reflect its human inhabitants, i.e., it should be the Great Good Place; for the more Eden-like it is, the greater the contradiction of murder. The country is preferable to the town, a well-to-do neighborhood (but not too well-to-do-or there will be a suspicion of ill-gotten gains) better than a slum. The corpse must shock not only because it is a corpse but also because, even for a corpse, it is shockingly out of place, as when a dog makes a mess on a drawing room carpet."
