For six days indeed she had been oblivious of the world outside, because it needed all her attention to follow the hot, red, quick sights which passed incessantly before her eyes. She knew that it was of enormous importance that she should attend to these sights and grasp their meaning, but she was always being just too late to hear or see something which would explain it all. For this reason, the faces,--Helen's face, the nurse's, Terence's, the doctor's,--which occasionally forced themselves very close to her, were worrying because they distracted her attention and she might miss the clue. However, on the fourth afternoon she was suddenly unable to keep Helen's face distinct from the sights themselves; her lips widened as she bent down over the bed, and she began to gabble unintelligibly like the rest. The sights were all concerned in some plot, some adventure, some escape.
