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.
