The Man with the Black Feather 

One evening last year I perceived in the waiting-room of my newspaper, Le Matin, a man dressed in black, his face heavy with the darkest despair, whose dry, dead eyes seemed to receive the images of things like unmoving mirrors.
He was seated; and there rested on his knees a sandalwood box inlaid with polished steel. An office-boy told me that he had sat there motionless, silent, awaiting my coming, for three mortal hours.
