In the silence when this voice ceased Amory realized that there were other things in the room besides people...over and around the figure crouched on the bed there hung an aura, gossamer as a moonbeam, tainted as stale, weak wine, yet a horror, diffusively brooding already over the three of them...and over by the window among the stirring curtains stood something else, featureless and indistinguishable, yet strangely familiar....Simultaneously two great cases presented themselves side by side to Amory; all that took place in his mind, then, occupied in actual time less than ten seconds.†
Chpt 2.4
...Amory knew that afterward Alec would secretly hate him for having done so much for him.... ...All this was flung before Amory like an opened scroll, while ulterior to him and speculating upon him were those two breathless, listening forces: the gossamer aura that hung over and about the girl and that familiar thing by the window.†
Chpt 2.4 *

Chpt 2.4

Chpt 2.5
