There exist beings who, for the sake of obtaining the key to these enigmas, which are, moreover, of no consequence whatever to them, spend more money, waste more time, take more trouble, than would be required for ten good actions, and that gratuitously, for their own pleasure, without receiving any other payment for their curiosity than curiosity. They will follow up such and such a man or woman for whole days; they will do sentry duty for hours at a time on the corners of the streets, under alleyway doors at night, in cold and rain; they will bribe errand-porters, they will make the drivers of hackney-coaches and lackeys tipsy, buy a waiting-maid, suborn a porter. Why? For no reason. A pure passion for seeing, knowing, and penetrating into things. A pure itch for talking. And often these secrets once known, these mysteries made public, these enigmas illuminated by the light of day, bring on catastrophies, duels, failures, the ruin of families, and broken lives, to the great joy of those who have “found out everything,” without any interest in the matter, and by pure instinct. A sad thing.
