It was a godless sound; one of those low-keyed, insidious outrages of nature which are not meant to be. To call it a dull wail, a doom-dragged whine or a hopeless howl of chorused anguish and stricken flesh without mind would be to miss its most quintessential loathsomeness and soul-sickening overtones. Was it for this that Ward had seemed to listen on that day he was removed? It was the most shocking thing that Willett had ever heard, and it continued from no determinate point as the doctor reached the bottom of the steps and cast his torchlight around on lofty corridor walls surmounted by Cyclopean vaulting and pierced by numberless black archways. The hall in which he stood was perhaps fourteen feet high to the middle of the vaulting and ten or twelve feet broad. Its pavement was of large chipped flagstones, and its walls and roof were of dressed masonry. Its length he could not imagine, for it stretched ahead indefinitely into the blackness. Of the archways, some had doors of the old six panelled colonial type, whilst others had none.
