For really it was the refinement of civilized cruelty, this spick, span, and ingenious affair of shining leather and gleaming steel, which hoisted you and tilted you and fitted reassuringly into the small of your back and cupped your head tenderly between padded cushions.

In the old days the victim's attention had at least been distracted by an ache in the back, a crick in the neck, pins and needles in the legs, and the uneasy tickling of plush under the palm. But now, too efficiently suspended between heaven and earth, you were at liberty to concentrate on hell.
