"But however this may be, there is no doubt at all but that what I might term the Haunting Essence which lived in the place, had become suddenly dangerous--deadly dangerous too, the old butler being nearly stabbed to death one night in the Chapel, with a peculiar old dagger. "It is, in fact, this dagger which is popularly supposed to 'haunt' the Chapel. At least, there has been always a story handed down in the family that this dagger would attack any enemy who should dare to venture into the Chapel, after nightfall. But, of course, this had been taken with just about the same amount of seriousness that people take most ghost tales, and that is not usually of a worryingly _real_ nature. I mean that most people never quite know how much or how little they believe of matters ab-human or ab-normal, and generally they never have an opportunity to learn. And, indeed, as you are all aware, I am as big a skeptic concerning the truth of ghost tales as any man you are likely to meet; only I am what I might term an unprejudiced skeptic. I am not given to either believing or disbelieving things 'on principle,' as I have found many idiots prone to be, and what is more, some of them not ashamed to boast of the insane fact. I view all reported 'hauntings' as unproven until I have examined into them, and I am bound to admit that ninety-nine cases in a hundred turn out to be sheer bosh and fancy. But the hundredth! Well, if it were not for the hundredth, I should have few stories to tell you--eh? "Of course, after the attack on the butler, it became evident that there was at least 'something' in the old story concerning the dagger, and I found everyone in a half belief that the queer old weapon did really strike the butler, either by the aid of some inherent force, which I found them peculiarly unable to explain, or else in the hand of some invisible thing or monster of the Outer World! "From considerable experience, I knew that it was much more likely that the butler had been 'knifed' by some vicious and quite material human! "Naturally, the first thing to do, was to test this probability of human agency, and I set to work to make a pretty drastic examination of the people who knew most about the tragedy. "The result of this examination, both pleased and surprised me, for it left me with very good reasons for belief that I had come upon one of those extraordinary rare 'true manifestations' of the extrusion of a Force from the Outside. In more popular phraseology--a genuine case of haunting. "These are the facts: On the previous Sunday evening but one, Sir Alfred Jarnock's household had attended family service, as usual, in the Chapel. You see, the Rector goes over to officiate twice each Sunday, after concluding his duties at the public Church about three miles away.
