And the characters on the seal are four thousand years old at least. Perhaps much more.”

“Is it a hoax?” I said.

“No, I anticipated that. I was not to be led to give my life to a practical joke. I have tested the matter very carefully. Only one person besides myself knows of the mere existence of that black seal. Besides, there are other reasons which I cannot enter into now.”

“But what does it all mean?” I said. “I cannot understand to what conclusion all this leads.”

“My dear Miss Lally, that is a question I would rather leave unanswered for some little time. Perhaps I shall never be able to say what secrets are held here in solution; a few vague hints, the outlines of village tragedies, a few marks done with red earth upon a rock, and an ancient seal. A queer set of data to go upon? Half a dozen pieces of evidence, and twenty years before even so much could be got together; and who knows what mirage or terra incognita5 may be beyond all this? I look across deep waters, Miss Lally, and the land beyond may be but a haze after all. But still I believe it is not so, and a few months will show whether I am right or wrong.”

He left me, and alone I endeavoured to fathom the mystery, wondering to what goal such eccentric odds and ends of evidence could lead. I myself am not wholly devoid of imagination, and I had reason to respect the professor’s solidity of intellect; yet I saw in the contents of the drawer but the materials of fantasy, and vainly tried to conceive what theory could be founded on the fragments that had been placed before me. Indeed, I could discover in what I had heard and seen but the first chapter of an extravagant romance; and yet deep in my heart I burned with curiosity, and day after day I looked eagerly in Professor Gregg’s face for some hint of what was to happen.

It was one evening after dinner that the word came.

“I hope you can make your preparations without much trouble,” he said suddenly to me. “We shall be leaving here in a week’s time.”

“Really!” I said in astonishment. “Where are we going?”

“I have taken a country house in the west of England, not far from Caermaen, a quiet little town, once a city, and the headquarters of a Roman legion. It is very dull there, but the country is pretty, and the air is wholesome.”

I detected a glint in his eyes, and guessed that this sudden move had some relation to our conversation of a few days before.

“I shall just take a few books with me,” said Professor Gregg, “that is all. Everything else will remain here for our return. I have got a holiday,” he went on, smiling at me, “and I shan’t be sorry to be quit for a time of my old bones and stones and rubbish. Do you know,” he went on, “I have been grinding away at facts for thirty years; it is time for fancies.”

The days passed quickly; I could see that the professor was all quivering with suppressed excitement, and I could scarce credit the eager appetence of his glance as we left the old manor-house behind us and began our journey. We set out at midday, and it was in the dusk of the evening that we arrived at a little country station. I was tired and excited, and the drive through the lanes seems all a dream. First the deserted streets of a forgotten village, while I heard Professor Gregg’s voice talking of the Augustan Legion and the clash of arms, and all the tremendous pomp that followed the eagles; then the broad river swimming to full tide with the last afterglow glimmering duskily in the yellow water, the wide meadows, the cornfields whitening, and the deep lane winding on the slope between the hills and the water. At last we began to ascend, and the air grew rarer. I looked down and saw the pure white mist tracking the outline of the river like a shroud, and a vague and shadowy country; imaginations and fantasy of swelling hills and hanging woods, and half-shaped outlines of hills beyond, and in the distance the glare of the furnace fire on the mountain, growing by turns a pillar of shining flame and fading to a dull point of red. We were slowly mounting a carriage drive, and then there came to me the cool breath and the secret of the great wood that was above us; I seemed to wander in its deepest depths, and there was the sound of trickling water, the scent of the green leaves, and the breath of the summer night. The carriage stopped at last, and I could scarcely distinguish the form of the house as I waited a moment at the pillared porch. The rest of the evening seemed a dream of strange things bounded by the great silence of the wood and the valley and the river.

The next morning, when I awoke and looked out of the bow window of the big, old-fashioned bedroom, I saw under a grey sky a country that was still all mystery. The long, lovely valley, with the river winding in and out below, crossed in mid-vision by a mediæval bridge of vaulted and buttressed stone, the clear presence of the rising ground beyond, and the woods that I had only seen in shadow the night before, seemed tinged with enchantment, and the soft breath of air that sighed in at the opened pane was like no other wind. I looked across the valley, and beyond, hill followed on hill as wave on wave, and here a faint blue pillar of smoke rose still in the morning air from the chimney of an ancient grey farmhouse, there was a rugged height crowned with dark firs, and in the distance I saw the white streak of a road that climbed and vanished into some unimagined country. But the boundary of all was a great wall of mountain, vast in the west, and ending like a fortress with a steep ascent and a domed tumulus clear against the sky.

I saw Professor Gregg walking up and down the terrace path below the windows, and it was evident that he was revelling in the sense of liberty, and the thought that he had for a while bidden good-bye to task-work. When I joined him there was exultation in his voice as he pointed out the sweep of valley and the river that wound beneath the lovely hills.

“Yes,” he said, “it is a strangely beautiful country; and to me, at least, it seems full of mystery.
