"O Miles," I began, "you don't believe such stuff as that?"

"I know you'll think me a coward," he interrupted. "I'm not afraid of most things, but I own frankly I hate to go near that horrid room. Mother had it furnished, and tried to use it one winter; but at the end of a month she got so frightened of the noise that she declared she'd never sit there again."

"I don't mind your ghost," I exclaimed, laughing. "You wait here, and I'll go back and listen to it again."

I entered the room, closed the door behind me, and stood waiting in a corner of the floor. I tried to persuade myself that I was not in the least frightened, but my heart beat faster than usual, and I strained my ears with almost painful intentness to catch the slightest sound. Within the last few moments the place seemed to have grown more cold, damp, and earthy than before; it felt like standing in a vault. Then, whether from the floor, ceiling, or solid oak panelling on the walls, I could not tell, came once more that mysterious sound, as though a person were humming with closed lips. I cast one hasty glance round the room, and made hurriedly for the door. Miles was still waiting in the passage.

"You didn't stay very long," he remarked with a quiet smile.

CHAPTER V.

NICHOLAS COVERTHORNE SHOWS HIS HAND.

In due course the summer holidays came to an end, and Miles and I met again at school. I had not been in his company five minutes before I noticed that his face wore a different look from when I had seen him last at Coverthorne; indeed, he seemed once more as sad and dejected as he had appeared immediately after his father's funeral.

"What's the matter with you? Have you been ill?" I asked; but he only shook his head and gave evasive replies.
