I waited a moment or two, and then followed him at a more leisurely pace. But I had not gone more than a hundred yards or so when I saw again his figure emerging from the gloom before me. In spite of myself I felt a little afraid. The modern ghost is so very material and commonplace in appearance, by all accounts, that one may easily mistake it for a real flesh and blood personality.

“Can this path be haunted?” I asked myself, and as the stranger came nearer I involuntarily shrank up a little towards the wall.

But as he was passing, the cheerful tones of his voice dispelled my misgivings. He made an almost imperceptible pause in his quick pace, exclaiming—

“I have found it! So sorry to have troubled you!” then hurried on, doubtless to enter the grounds at the same spot whence he had emerged, and where my common-sense told me there must be a door of some kind.

“I shall make Isabel come this way to-morrow to look for it,” I said to myself, and I hurried home, eager to relate to her my exciting adventure.

She was looking out for me, walking up and down the drive.

“I could have come with you if you had waited five minutes. Papa only wanted me for a moment or two, after all. It is rather too dark for you to be out alone, and I didn’t know which way you had gone,” she said.

“O Isabel!” I exclaimed. “Something so interesting has happened;” and I quickly related the incident, my friend listening attentively.

“Was it a Grey or a ghost?” I ended up half jokingly, but Isabel’s face was full of grave consideration.

“I never heard of a ghost in or about the Grim House,” she said seriously. “But still less can I think it was one of the Grey brothers. The elder one is quite old-looking, peculiarly worn and haggard, and the other, as I have told you, though he has a sweet, calm face, is an unmistakable cripple. He walks very slowly, and generally with a crutch.”
