And, always when he returned to the inn about the hour of sunset, he saw the figures of the townsfolk stealing through the dusk from their shop doors, moving sentry-wise to and fro at the corners of the streets, yet always vanishing silently like shadows at his near approach.  And as the inn invariably closed its doors at ten o’clock he had never yet found the opportunity he rather half-heartedly sought to see for himself what account the town could give of itself at night.

“—­a cause du sommeil et a cause des chats”—­the words now rang in his ears more and more often, though still as yet without any definite meaning.

Moreover, something made him sleep like the dead.

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!

This is difficult to describe in words, and it was more by gesture and the expression of his face that he conveyed to Dr. Silence the state of impotence he had reached.  All this spying and watching, he said, had as it were spun a net about his feet so that he was trapped and powerless to escape; he felt like a fly that had blundered into the intricacies of a great web; he was caught, imprisoned, and could not get away.  It was a distressing sensation.  A numbness had crept over his will till it had become almost incapable of decision.  The mere thought of vigorous action—­action towards escape—­began to terrify him.  All the currents of his life had turned inwards upon himself, striving to bring to the surface something that lay buried almost beyond reach, determined to force his recognition of something he had long forgotten—­forgotten years upon years, centuries almost ago.  It seemed as though a window deep within his being would presently open and reveal an entirely new world, yet somehow a world that was not unfamiliar.  Beyond that, again, he fancied a great curtain hung; and when that too rolled up he would see still farther into this region and at last understand something of the secret life of these extraordinary people.
