Don't tell me that it wasn't a knocker. I had seen it often enough, and I ought to know. So ought the three-o'clock beer, in dirty high-lows, swinging himself over the railing, or executing a demoniacal jig upon the doorstep; so ought the butcher, although butchers as a general thing are scornful of such trifles; so ought the postman, to whom knockers of the most extravagant description were merely human weaknesses, that were to be pitied and used. And so ought, for the matter of that, etc., etc., etc. But then it was SUCH a knocker. A wild, extravagant, and utterly incomprehensible knocker. A knocker so mysterious and suspicious that Policeman X 37, first coming upon it, felt inclined to take it instantly in custody, but compromised with his professional instincts by sharply and sternly noting it with an eye that admitted of no nonsense, but confidently expected to detect its secret yet. An ugly knocker; a knocker with a hard, human face, that was a type of the harder human face within. A human face that held between its teeth a brazen rod. So hereafter, in the mysterious future should be held, etc., etc. But if the knocker had a fierce human aspect in the glare of day, you should have seen it at night, when it peered out of the gathering shadows and suggested an ambushed figure; when the light of the street lamps fell upon it, and wrought a play of sinister expression in its hard outlines; when it seemed to wink meaningly at a shrouded figure who, as the night fell darkly, crept up the steps and passed into the mysterious house; when the swinging door disclosed a black passage into which the figure seemed to lose itself and become a part of the mysterious gloom; when the night grew boisterous and the fierce wind made furious charges at the knocker, as if to wrench it off and carry it away in triumph. Such a night as this. It was a wild and pitiless wind. A wind that had commenced life as a gentle country zephyr, but wandering through manufacturing towns had become demoralized, and reaching the city had plunged into extravagant dissipation and wild excesses. A roistering wind that indulged in Bacchanalian shouts on the street corners, that knocked off the hats from the heads of helpless passengers, and then fulfilled its duties by speeding away, like all young prodigals,--to sea. He sat alone in a gloomy library listening to the wind that roared in the chimney. Around him novels and story-books were strewn thickly; in his lap he held one with its pages freshly cut, and turned the leaves wearily until his eyes rested upon a portrait in its frontispiece. And as the wind howled the more fiercely, and the darkness without fell blacker, a strange and fateful likeness to that portrait appeared above his chair and leaned upon his shoulder. The Haunted Man gazed at the portrait and sighed. The figure gazed at the portrait and sighed too. "Here again?" said the Haunted Man. "Here again," it repeated in a low voice.
