But perhaps at this point I may do well to explain to my readers (before they are too frightened to listen to me) how I came to be beating on the door of Buggam Grange at nightfall on a gloomy November evening.

A year before I had been sitting with Sir Jeremy Buggam, the present baronet, on the verandah of his ranch in California.

"So you don't believe in the supernatural?" he was saying.

"Not in the slightest," I answered, lighting a cigar as I spoke. When I want to speak very positively, I generally light a cigar as I speak.

"Well, at any rate, Digby," said Sir Jeremy, "Buggam Grange is haunted. If you want to be assured of it go down there any time and spend the night and you'll see for yourself."

"My dear fellow," I replied, "nothing will give me greater pleasure. I shall be back in England in six weeks, and I shall be delighted to put your ideas to the test. Now tell me," I added somewhat cynically, "is there any particular season or day when your Grange is supposed to be specially terrible?"

Sir Jeremy looked at me strangely. "Why do you ask that?" he said. "Have you heard the story of the Grange?"

"Never heard of the place in my life," I answered cheerily. "Till you mentioned it to-night, my dear fellow, I hadn't the remotest idea that you still owned property in England."

"The Grange is shut up," said Sir Jeremy, "and has been for twenty years. But I keep a man there—Horrod—he was butler in my father's time and before. If you care to go, I'll write him that you're coming. And, since you are taking your own fate in your hands, the fifteenth of November is the day."

At that moment Lady Buggam and Clara and the other girls came trooping out on the verandah, and the whole thing passed clean out of my mind. Nor did I think of it again until I was back in London. Then, by one of those strange coincidences or premonitions—call it what you will—it suddenly occurred to me one morning that it was the fifteenth of November. Whether Sir Jeremy had written to Horrod or not, I did not know. But none the less nightfall found me, as I have described, knocking at the door of Buggam Grange.
