Suddenly across the gloom shot a tiny spear of light, and momentarily as we watched, it grew larger and longer, till a tall beam, as from some window cut in the rock opposite, was shed on the bank below us. It moved slowly, imperceptibly to the left till it struck full between the two black figures standing there, and shone with a curious bluish gleam on the flat stone in front of them. Then the roar of the river was suddenly overscored by a dreadful screaming voice, the voice of a woman, and from her side her arms shot up and out as if in invocation of some power. At first I could catch none of the words, but soon from repetition they began to convey an intelligible message to my brain, and I was listening as in the paralytic horror of nightmare to a bellowing of the most hideous and unnameable profanity. What I heard I cannot bring myself to record; suffice it to say that Satan was invoked by every adoring and reverent name, that cursing and unspeakable malediction was poured forth on Him whom we hold most holy. Then the yelling voice ceased as suddenly as it had begun, and for a moment there was silence again, but for the reverberating river.
Then once more that horror of sound was uplifted.
“So, Catrine Gordon,” it cried, “I bid ye in the name of my master and your’s to rise from where ye lie. Up with ye—up!”
Once more there was silence; then I heard Hugh at my elbow draw a quick sobbing breath, and his finger pointed unsteadily to the dead black water below the rock. And I too looked and saw.
Right under the rock there appeared a pale subaqueous light, which waved and quivered in the stream. At first it was very small and dim, but as we looked it seemed to swim upwards from remote depths and grew larger till I suppose the space of some square yard was illuminated by it. Then the surface of the water was broken, and a head, the head of a girl, dead-white and with long, flowing hair, appeared above the stream. Her eyes were shut, the corners of her mouth drooped as in sleep, and the moving water stood in a frill round her neck. Higher and higher rose the figure out of the tide, till at last it stood, luminous in itself, so it appeared, up to the middle. The head was bent down over the breast, and the hands clasped together. As it emerged from the water it seemed to get nearer, and was by now halfway across the pool, moving quietly and steadily against the great flood of the hurrying river.
Then I heard a man’s voice crying out in a sort of strangled agony.
“Catrine!” it cried; “Catrine! In God’s name; in God’s name!”
In two strides Sandy had rushed down the steep bank, and hurled himself out into that mad swirl of waters. For one moment I saw his arms flung up into the sky, the next he had altogether gone. And on the utterance of that name the unholy vision had vanished too, while simultaneously there burst in front of us a light so blinding, followed by a crack of thunder so appalling to the senses, that I know I just hid my face in my hands. At once, as if the floodgates of the sky had been opened, the deluge was on us, not like rain, but like one sheet of solid water, so that we cowered under it. Any hope or attempt to rescue Sandy was out of the question; to dive into that whirlpool of mad water meant instant death, and even had it been possible for any swimmer to live there, in the blackness of the night there was absolutely no chance of finding him. Besides, even if it had been possible to save him, I doubt whether I was sufficiently master of my flesh and blood as to endure to plunge where that apparition had risen.
Then, as we lay there, another horror filled and possessed my mind. Somewhere close to us in the darkness was that woman whose yelling voice just now had made my blood run ice-cold, while it brought the streaming sweat to my forehead. At that moment I turned to Hugh.
“I cannot stop here,” I said. “I must run, run right away. Where is she?”
“Did you not see?” he asked.
“No. What happened?”
“The lightning struck the stone within a few inches of where she was standing. We—we must go and look for her.”
I followed him down the slope, shaking as if I had the palsy, and groping with my hands on the ground in front of me, in deadly terror of encountering something human. The thunderclouds had in the last few minutes spread over the moon, so that no ray from the window in the rock guided our search. But up and down the bank from the stone that lay shattered there to the edge of the pool we groped and stumbled, but found nothing. At length we gave it up: it seemed morally certain that she, too, had rolled down the bank after the lightning stroke, and lay somewhere deep in the pool from which she had called the dead.
None fished the pool next day, but men with dragnets came from Brora. Right under the rock in the backwater lay two bodies, close together, Sandy and the dead girl. Of the other they found nothing.
It would seem, then, that Catrine Gordon, in answer to Sandy’s letter, left Inverness in heavy trouble. What happened afterwards can only be conjectured, but it seems likely she took the shortcut to Gavon, meaning to cross the river on the boulders above the Picts’ pool. But whether she slipped accidentally in her passage, and so was drawn down by the hungry water, or whether, unable to face the future, she
