" when Goblin clutches me by the wrist, and lays, not her skinny finger, but the handle of a key, upon her lip.  She invites me, with a jerk, to follow her.  I do so.  She leads me out into a room adjoining - a rugged room, with a funnel-shaped, contracting roof, open at the top, to the bright day.  I ask her what it is.  She folds her arms, leers hideously, and stares.  I ask again.  She glances round, to see that all the little company are there; sits down upon a mound of stones; throws up her arms, and yells out, like a fiend, ‘La Salle de la Question!’
The Chamber of Torture!  And the roof was made of that shape to stifle the victim’s cries!  Oh Goblin, Goblin, let us think of this awhile, in silence.  Peace, Goblin!  Sit with your short arms crossed on your short legs, upon that heap of stones, for only five minutes, and then flame out again. "
