can see him through them all. Duncan, my dear, when you suspect
anything, do not be too incredulous. This human demon is of course a
wizard still, and knows how to make himself, as well as anything he
touches, take a quite different appearance from the real one; only every
appearance must bear some resemblance, however distant, to the natural
form. That man you saw at the door was the phantom of which I have been
telling you. What he is after now, of course, I cannot tell; but you
must keep a bold heart, and a firm and wary foot, as you go home
to-night."

I showed some surprise, I do not doubt; and, perhaps, some fear as well;
but I only said, "How do you know him, Margaret?"

"I can hardly tell you," she replied; "but I do know him. I think he
hates me. Often, of a wild night, when there is moonlight enough by
fits, I see him tearing around this little valley, just on the top
edge--all round; the lady's hair and the horses mane and tail driving
far behind, and mingling, vaporous, with the stormy clouds. About he
goes, in wild careering gallop; now lost as the moon goes in, then
visible far round when she looks out again--an airy, pale-grey spectre,
which few eyes but mine could see; for, as far as I am aware, no one of
the family but myself has ever possessed the double gift of seeing and
hearing both. In this case I hear no sound, except now and then a clank
from the broken shoe. But I did not mean to tell you that I had ever
seen him. I am not a bit afraid of him. He cannot do more than he may.
His power is limited; else ill enough would he work, the miscreant."

"But," said I, "what has all this, terrible as it is, to do with the
fright you took at my telling you that I had heard the sound of the
broken shoe? Surely you are not afraid of only a storm?"
