“There was the distinct sound of low, whispered words! Gabrielle held her breath to listen. She tried to distinguish what the words were, but in vain. Then she endeavoured to determine whence they emanated, but was unable to do so. Again they sounded—again—and yet again. Then there was another voice, still low, still whispering, but not quite so deep as the first. It sounded like a woman's.
Local tradition had it that the place held the ghosts of those who had died in agony within its noisome dungeons; but she had always been far too matter-of-fact to accept stories of the supernatural. Yet at that moment her ears did not deceive her. That pile of grim, gaunt ruins was a House of Whispers!
...But her thoughts were very naturally full of the weird story told of the dead and gone owners of Glencardine. She recollected that horrible story of the Ghaist of Manse and of the spectre of Bridgend. In the library she had, a year ago, discovered a strange old book—one which sixty years before had been in universal circulation—entitled Satan's Invisible World Discovered, and she had read it from beginning to end.”
