As for myself, I hardly knew whether to be offended or amused, curious or merely matter-of-fact. I'm afraid that amusement won the day. 'And what do you suspect, Mrs Cloris? Ghosts rattling chains?'
But she only looked at me oddly. 'Ghosts there may be. But it's not ghosts in the walls. It's not ghosts that wail and blubber like the damned and crash and blunder away in the darkness. It's-'
'Come, Mrs Cloris,' I prompted her. 'You've come this far. Now can you finish what you've begun?'
The strangest expression of terror, pique, and - I would swear to it - religous awe passed over her face. 'Some die not' she whispered. 'Some live in the twilight shadows Between to serve - Him!'
And that was the end. For some minutes I continued to tax her, but she grew only more obstinate and would say no more. At last I desisted, fearing she might gather herself up and quit the premises.
This is the end of one episode, but a second occurred the following evening. Calvin had laid a fire downstairs and I was sitting in the living-room, drowsing over a copy of The Intelligencer and listening to the sound of wind-driven rain on the large bay window. I felt comfortable as only one can on such a night, when all is miserable outside and all is warmth and comfort inside; but a moment later Cal appeared at the door, looking excited and a bit nervous.
'Are you awake, sir?' he asked.
'Barely,' I said. 'What is it?'
'I've found something upstairs I think you should see,' he responded, with the same air of suppressed excitement.
I got up and followed him. As we climbed the wide stairs, Calvin said: 'I was reading a book in the upstairs study - a rather strange one when I heard a noise in the wall.'
'Rats,' I said. 'Is that all?'
He paused on the landing, looking at me solemnly. The lamp he held cast weird, lurking shadows on the dark draperies and on the half-seen portraits that seemed now to leer rather than smile. Outside the wind rose to a brief scream and then subsided grudgingly.
'Not rats,' Cal said. 'There was a kind of blundering, thudding sound from behind the book-cases, and then a horrible gurgling - horrible, sir. And scratching, as if something were struggling to get out. . . to get at me!'
You can imagine my amazement, Bones. Calvin is not the type to give way to hysterical flights of imagination. It began to seem that there was a mystery here after all - and perhaps an ugly one indeed.
'What then?' I asked him. We had resumed down the hall, and I could see the light from the study spilling forth on to the floor of the gallery. I viewed it with some trepidation; the night seemed no longer comfortable.
'The scratching noise stopped. After a moment the thudding, shuffling sounds began again, this time moving away from me. I paused once, and I swear I heard a strange, almost inaudible laugh! I went to the book-case and began to push and pull, thinking there might be a partition, or a secret door.'
'You found one?'
Cal paused at the door to the study. 'No - but I found this!'
We stepped in and I saw a square black hole in the left case. The books at that point were nothing but dummies, and what Cal had found was a small hiding place. I flashed my lamp within it and saw nothing but a thick fall of dust, dust which must have been decades old.
'There was only this,' Cal said quietly, and handed me a yellowed foolscap. The thing was a map, drawn in spider-thin strokes of black ink - the map of a town or village. There were perhaps seven buildings, and one, clearly marked with a steeple, bore this legend beneath it: The Worm That Doth Corrupt.
In the upper left corner, to what would have been the north-west of this little village, an arrow pointed. Inscribed beneath it: Chapelwaite.
Calvin said: 'In town, sir, someone rather superstitiously mentioned a deserted village called Jerusalem's Lot. It's a place they steer clear of.'
'But this?' I asked, fingering the odd legend below the steeple.
'I don't know.'
A memory of Mrs Cloris, adamant yet fearful, passed through my mind. 'The Worm . . .' I muttered.
'Do you know something, Mr Boone?'
'Perhaps. . . it might be amusing to have a look for this town tomorrow, do you think, Cal?'
He nodded, eyes lighting. We spent almost an hour after this looking for some breach in the wall behind the cubbyhole Cal had found, but with no success. Nor was there a recurrence of the noises Cal had described.
We retired with no further adventure that night.
