I did not pause long on the path, but resolutely entered the open house door and closed it behind me. It had cost me a distinct psychological effort to do so, and now that I was shut inside I had a momentary longing for precipitate retreat. Not that the place was in the least sinister in visual suggestion; on the contrary, I thought the graceful late-colonial hallway very tasteful and wholesome, and admired the evident breeding of the man who had furnished it. What made me wish to flee was something very attenuated and indefinable. Perhaps it was a certain odd odour which I thought I noticed—though I well knew how common musty odours are in even the best of ancient farmhouses.
