To me, detective stories are a great solace, a sort of mental knitting, where it doesn't matter if you drop a stitch."

[From a letter to George Lyttelton]

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."

(The guilty vicarage: Notes on the detective story, by an addict, Harper's Magazine, May 1948)

The detective story, as created by Poe, is something as specialised and as intellectual as a chess problem, whereas the best English detective fiction has relied less on the beauty of the mathematical problem and much more on the intangible human element. [...] In The Moonstone the mystery is finally solved, not altogether by human ingenuity, but largely by accident. Since Collins, the best heroes of English detective fiction have been, like Sergeant Cuff, fallible.

Perhaps this is the purpose of detective investigations, real and fictional -- to transform sensation, horror and grief into a puzzle, and then to solve the puzzle, to make it go away. 'The detective story,' observed Raymond Chandler in 1949, 'is a tragedy with a happy ending.' A storybook detective starts by confronting us with a murder and ends by absolving us of it. He clears us of guilt. He relieves us of uncertainty. He removes us from the presence of death.

Down these mean streets a man must go who is not himself mean, who is neither tarnished nor afraid. The detective must be a complete man and a common man and yet an unusual man. He must be, to use a rather weathered phrase, a man of honor.

There is no mystery to happiness. Unhappy men are all alike. Some wound they suffered long ago, some wish denied, some blow to pride, some kindling spark of love put out by scorn -- or worse, indifference -- cleaves to them, or they to it, and so they live each day within a shroud of yesterdays. The happy man dies not look back. He doesn't look ahead. He lives in the present.
