“As for me, I lived for more than three months in one of the cheapest of those spy-hole-ridden bedrooms. I completed my education there. Through three or four tiny holes, which must have been bored by some neglected genius of espionage, I watched people when they thought they were alone. I saw things which walls and the darkness were made to conceal; I heard things which no man was supposed to hear. It was degrading, but impossible to resist. I stooped. I stooped to the keyhole of hell, and I learned the secrets of the damned. - from "The Devil that Troubled the Chessboard”
