“‘[I]f you are interested in life it never lets you down. I am
interested in the blueness of the cheese. You don’t do crosswords, do
you, Mr Wormold? I do, and they are like people: one reaches an end. I
can finish any crossword within an hour, but I have a discovery
concerned with the blueness of cheese that will never come to a
conclusion—although of course one dreams that perhaps a time might come
. . . One day I must show you my laboratory.’”

—Graham Greene, Our Man in Havana, 1958.
