I do not recall distinctly when it began, but it was months ago. The general tension was horrible. To a season of political and social upheaval was added a strange and brooding apprehension of hideous physical danger; a danger widespread and all-embracing, such a danger as may be imagined only in the most terrible phantasms of the night. I recall that the people went about with pale and worried faces, and whispered warnings and prophecies which no one dared consciously repeat or acknowledge to himself that he had heard.
