evidently deepened, nobody would have felt any further mystery than what, from the very first, rested upon the persons and the motives of the murderers. But, as it was, when, in ten separate cases of exterminating carnage, the astounded police, after an examination the most searching, pursued from day to day, and almost exhausting the patience by the minuteness of the investigation, had finally pronounced that no attempt apparently had been made to benefit by any of the signals preconcerted, that no footstep apparently had moved in that direction--then, and after that result, a blind misery of fear fell upon the population, so much the worse than any anguish of a beleaguered city that is awaiting the storming fury of a victorious enemy, by how much the shadowy, the uncertain, the infinite, is at all times more potent in mastering the mind than a danger that is known, measurable, palpable, and human. The very police, instead of offering protection or encouragement, were seized with terror for themselves. And the general feeling, as it was described to me by a grave citizen whom I met in a morning walk (for the overmastering sense of a public calamity broke down every barrier of reserve, and all men talked freely to all men in the streets, as they would have done during the rockings of an earthquake), was, even among the boldest, like that which sometimes takes possession of the mind in dreams--when one feels oneself sleeping alone, utterly divided from all call or hearing of friends, doors open that should be shut, or unlocked that should be triply secured, the very walls gone, barriers swallowed up by unknown abysses, nothing around one but frail curtains, and a world of illimitable night, whisperings at a distance, correspondence going on between darkness and darkness, like one deep calling to another, and the dreamer's own heart the center from which the whole network of this unimaginable chaos radiates, by means of which the blank PRIVATIONS of silence and darkness become powers the most POSITIVE and awful.
