But that mud would have dried long ago, and this showed signs of damp!

Eagerly, critically, I bent and studied the floor in the full glare of my torch. There were dubious faintly moist impressions, of feet, I believed; but I could make nothing of them. No entire footprint was evident. Over the general surface of the dirt, however, something sopping wet had recently been trailed, but not so heavily as to disturb the topography of the mud. The little ridges and knolls left by Salt’s rubber boots remained intact, but portions of that microscopic countryside looked as if they were recovering from an inundation; in one or two hollows there were positive pools, one-sixteenth of an inch deep.

Something exceedingly wet, but not very heavy—what else but the gown of the creature that had fled from Aire and me and plunged into the stream? Only, how in the name of magic did that creature evade us to get here, unless it skipped up the stream, which both Aire and I are prepared to attest on oath it did not do?

A flat-headed aperture led the way across the bridge between the towers. In that direction the water-trail appeared to tend, although at the edge of the dirt, where the gown had been drawn along the stones themselves, almost complete evaporation had taken place. Further along there was no sign of damp at all; I suppose the intruder had observed the puddles he was making and had lifted the garment clear from the floor, perhaps doffed it and rolled it under his arm.

I had to crouch nearly double in that low passageway to reach the inner room, which now I believed to be the headquarters of Parson Lolly. My light, cast ahead, showed that it was a chamber of identical mould with the one I had just quitted, and, much to my relief, it was empty. One difference there was, indeed: the corresponding stairway which led down from this tower had for some reason been walled up. I tested the mortared stones; I pounded them with my fist; I butted them with my shoulder. They were sound and secure, leaving no doubt that those stairs condemned to everlasting darkness held no secret connected with the present mysteries.

When I had reached this comfortable certainty, I made a detailed search of the turret. Someone, for sure, had been in the habit of coming there; I found what appeared to me sufficient evidence of occupation, and of hurried, perhaps permanent, departure.

There were pencil-whittlings on the floor, from an indelible pencil; I know the nasty taste of the aniline preparation. Now, when I re-examined the Parson’s placard inside the House this evening, I saw, though I did not comment on the fact, that such a pencil had been used in writing it.

There were two or three dark stains, splashes now quite dried, which yet had a dim, offensive odour when my nose was close to them. To my mind, no more proof is needed that a young pig was murdered here.

There were a few short lengths, an inch to four or five inches, of some pliant fibrous wood, perhaps bamboo, which I cannot account for. With these, perhaps, are associated the fragments of black crepe I found cut in wedges, rhombs, and various irregular shapes.

I detected, while bending near one of the slender openings, a sub-acrid, faded scent, which seemed specially localized on the sill, so to speak, of the window, as if some pungent stuff had once been spilt there and removed. In its proper context the source of the odour would, I am sure, have been obvious in an instant; yet here it baffled me.
