I rose, opened my window and listened; but the yard was broad and no sound reached me from the stable.
I waited there five minutes perhaps.

The inn-keeper did not reappear, so I returned to my place.

I had finished my meal before he came out.

This time I was tolerably sure that the door was closed behind him by another hand, and I fancied that I heard the click of a lock.

Also I noticed that the letter was no longer visible--of course, he might have put it in his pocket.
