This was my first observation.

The second was that the colours of the hearth-rug had gained in freshness, and that a dark spot just beyond it--a spot which in my first exploration I had half-amusedly taken for a blood-stain--was not reflected in the glass.
As I leant back and gazed, with my hands in my lap, I remember there was some difficulty in determining whether the tune by which I was still haunted ran in my head or was tinkling from within the old spinet by the window.

But after a while the music, whencesoever it came, faded away and ceased.

A dead silence held everything for about thirty seconds.
And then, still looking in the mirror, I saw the door behind me open slowly.
The next moment, two persons noiselessly entered the room--a young man and a girl.

They wore the dress of the early Georgian days, as well as I could see; for the girl was wrapped in a cloak with a hood that almost concealed her face, while the man wore a heavy riding-coat.
