The position now, however, wore a different aspect. Her mental faculties were more on the alert than they had been; as it seemed to her, they kept coming and going; so that now she saw clearly, and now not at all. So far as they enabled her to judge, now, again, her only hope of immunity rested on her continuing undiscovered. If they found her all sorts of dreadful consequences would immediately result. For one thing they would quite probably accuse her of having had at least a hand in her guardian's death, if she were not the actual assassin; not unnaturally taking it for granted that her persistent concealment could only have a criminal meaning. She could only disprove the charge, if it could be disproved, by shifting the onus of guilt on to the vanished stranger's shoulders. Already--though, as yet, the thing might not be acknowledged to herself--in her heart she had arrived at a final resolution that under no conceivable circumstances would she bear witness against him. Happen what might; where, in this matter, he was concerned she would be dumb. Although she had not formulated it in so many words, she felt that, in what had been done, they had been partners, even friends; that, though unwittingly, it had been done for her. Therefore, if to prove her innocence, it should become necessary to prove his guilt, her doom was sealed. In that case, so soon as they drew aside the curtain, and found her behind it, her fate was sealed. It amazed her to think that she had not been discovered already. She herself was so conscious of her imminent proximity to what had taken place; was so well aware of how slender a protection that screen of hanging drapery really was; that it bewildered her that she should have played, with complete impunity, for so long the part of a spy--and more. But the continuance of such impunity could not be counted on. When the police came--and, possibly, they were already on the threshold--the room would be searched for evidence. Then, in a moment, her hiding-place would be revealed. She could not wait for that; she must get away out of the room, before they came. But how?--since the door was locked.
