slope a scrambling path, where progress demands both caution and activity, conducts to the head of the pool which lies immediately beneath it. A gate-chamber still roofed over exists in the solid wall: inside there are foundation indications of three rooms, and in the centre of all a very deep hole, probably a well. Finally, just outside the postern leading to the river is a small artificially levelled platform, some twenty feet across, as if made to support some super-incumbent edifice. Certain stone slabs and blocks are dispersed over it.
Brora, the post-town of Gavon, lies some six miles to the south-west, and from it a track over the moor leads to the rapids immediately above the Picts’ pool, across which by somewhat extravagant striding from boulder to boulder a man can pass dry-foot when the river is low, and make his way up a steep path to the north of the basaltic rock, and so to the village. But this transit demands a steady head, and at the best is a somewhat giddy passage. Otherwise the road between it and Brora lies in a long detour higher up the moor, passing by the gates of Gavon Lodge, where I was stopping. For some vague and ill-defined reason the pool itself and the Picts’ Castle had an uneasy reputation on the countryside, and several times trudging back from a day’s fishing I have known my gillie take a longish circuit, though heavy with fish, rather than make this short cut in the dusk by the castle. On the first occasion when Sandy, a strapping yellow-bearded viking of twenty-five, did this he gave as a reason that the ground ’round about the castle was “mossy,” though as a God-fearing man he must have known he lied. But on another occasion he was more frank, and said that the Picts’ pool was “no canny” after sunset. I am now inclined to agree with him, though, when he lied about it, I think it was because as a God-fearing man he feared the devil also.
It was on the evening of September 14 that I was walking back with my host, Hugh Graham, from the forest beyond the lodge. It had been a day unseasonably hot for the time of year, and the hills were blanketed with soft, furry clouds. Sandy, the gillie of whom I have spoken, was behind with the ponies, and, idly enough, I told Hugh about his strange distaste for the Picts’ pool after sunset. He listened, frowning a little.
“That’s curious,” he said. “I know there is some dim local superstition about the place, but last year certainly Sandy used to laugh at it. I remember asking him what ailed the place, and he said he thought nothing about the rubbish folk talked. But this year you say he avoids it.”
“On several occasions with me he has done so.”
Hugh smoked a while in silence, striding noiselessly over the dusky fragrant heather.
“Poor chap,” he said, “I don’t know what to do about him. He’s becoming useless.”
“Drink?” I asked.
“Yes, drink in a secondary manner. But trouble led to drink, and trouble, I am afraid, is leading him to worse than drink.”
“The only thing worse than drink is the devil,” I remarked.
“Precisely. That’s where he is going. He goes there often.”
“What on earth do you mean?” I asked.
“Well, it’s rather curious,” said Hugh. “You know I dabble a bit in folklore and local superstition, and I believe I am on the track of something odder than odd. Just wait a moment.”
We stood there in the gathering dusk till the ponies laboured up the hillside to us, Sandy with his six feet of lithe strength strolling easily beside them up the steep brae, as if his long day’s trudging had but served to half awaken his dormant powers of limb.
“Going to see Mistress Macpherson again tonight?” asked Hugh.
“Aye, puir body,” said Sandy. “She’s auld, and she’s lone.”
“Very kind of you, Sandy,” said Hugh, and we walked on.
“What then?” I asked when the ponies had fallen behind again.
“Why, superstition lingers here,” said Hugh, “and it’s supposed she’s a witch. To be quite candid with you, the thing interests me a good deal. Supposing you asked me, on oath, whether I believed in witches, I should say ‘No.’ But if you asked me again, on oath, whether I suspected I believed in them, I should, I think, say ‘Yes.’ And the fifteenth of this month—tomorrow—is Gavon’s Eve.”
“And what in Heaven’s name is that?” I asked. “And who is Gavon? And what’s the trouble?”
“Well, Gavon is the person, I suppose, not saint, who is what we should call the eponymous hero of this district. And the trouble is Sandy’s trouble. Rather a long story. But there’s a long mile in front of us yet, if you care to be told.”
During that mile I heard. Sandy had been engaged a year ago to girl of Gavon who was in service at Inverness. In March last he had gone, without giving notice, to see her, and as he walked up the street in which her mistress’s house stood, had met her suddenly face to face, in company with a man whose clipped speech betrayed him English, whose manner a kind of gentleman. He had a flourish of his hat for Sandy, pleasure to see him, and scarcely any need of explanation as to how he came to be walking with Catrine. It was the most natural thing possible, for a city like Inverness boasted its innocent urbanities, and a girl could stroll with a man. And for the time, since also Catrine was so frankly pleased to see him, Sandy was satisfied. But after his return to Gavon, suspicion, fungus-like, grew rank in his mind, with the result that a month ago he had, with infinite pains and blottings, written a letter to Catrine, urging her return and immediate marriage. Thereafter it was known that she had left Inverness; it was known that she had arrived by train at Brora. From Brora she had started to walked across the moor by the path leading just above the Picts’ Castle, crossing the rapids to Gavon, leaving her box to be sent by the carrier. But at Gavon she had never arrived. Also it was said that, although it was hot afternoon, she wore a big cloak.
By this time we had come to the lodge, the lights of which showed dim and blurred through the thick hill-mists that had streamed sullenly down from the higher ground.
“And the rest,” said Hugh, “which is as fantastic as this is sober fact, I will tell you later.”
Now, a fruit-bearing determination to go to bed is, to my mind, as difficult to ripen as a fruit-bearing determination to get up, and in spite of our long day, I was glad when Hugh (the rest of the men having yawned themselves out of the smoking-room) came back from the hospitable dispensing of bedroom candlesticks with a briskness that denoted that, as far as he was concerned, the distressing determination was not imminent.
“As regards Sandy,” I suggested.
“Ah, I also was thinking of that,” he said. “Well, Catrine Gordon left Brora, and never arrived here. That is fact. Now for what remains. Have you any remembrance of a woman always alone walking about the moor by the loch? I think I once called your attention to her.”
“Yes, I remember,” I said. “Not Catrine, surely; a very old woman, awful to look at.
“Moustache, whiskers, and muttering to herself. Always looking at the ground, too.”
“Yes, that is she—not Catrine. Catrine! My word, a May morning! But the other—it is Mrs. Macpherson, reputed witch. Well, Sandy trudges there, a mile and more away, every night to see her. You know Sandy: Adonis of the north. Now, can you account by any natural explanation for that fact? That he goes off after a long day to see an old hag in the hills?”
“It would seem unlikely,” said I.
“Unlikely! Well, yes, unlikely.”
Hugh got up from his chair and crossed the room to where a bookcase of rather fusty-looking volumes stood between windows. He took a small morocco—backed book from a top shelf.
“Superstitions of Sutherlandshire,” he said, as he handed it to me. “Turn to page 128, and read.”
“September 15 appears to have been the date of what we may call this devil festival. On the night of that day the powers of darkness held pre-eminent dominion, and over-rode for any who were abroad that night and
