It was, I think, on the fifth day—though in this detail his story sometimes varied—that he made a definite discovery which increased his alarm and brought him up to a rather sharp climax. Before that he had already noticed that a change was going forward and certain subtle transformations being brought about in his character which modified several of his minor habits. And he had affected to ignore them. Here, however, was something he could no longer ignore; and it startled him.
At the best of times he was never very positive, always negative rather, compliant and acquiescent; yet, when necessity arose he was capable of reasonably vigorous action and could take a strongish decision. The discovery he now made that brought him up with such a sharp turn was that this power had positively dwindled to nothing. He found it impossible to make up his mind. For, on this fifth day, he realised that he had stayed long enough in the town and that for reasons he could only vaguely define to himself it was wiser and safer that he should leave.
And he found that he could not leave!
