We rode in silence, for Pierrebon, to say truth, was uneasy at the uncanny stillness, and that awe with which Nature in her lonely grandeur inspires the dullest of mortals had begun to fill us. And so no word was spoken. In and out the track wound, until at last it brought us to the very heart of the forest, where the shadows lay black and deep. Around us on every side the huge and aged trees, stretching in long lines of receding obscurity, stood like a phantom army of giants guarding some dreadful secret of the past. Twisted, distorted, and bent, with hairy, moss-grown trunks from which the decaying bark peeled like the mouldering cement on some old and forgotten ruin, the kings of the forest stood silent and grim, their branches stretched out in grisly menace--giant arms that threatened death to all who approached. Deeper and yet more deep we rode into the gloom, though the sunset yet clung in a girdle of fire round the horizon, casting red blades of light between the tree trunks; and Pierrebon's cheek grew pale, for goblin and gnome and fay lived to him, and even I, who did not believe, felt if my sword played freely in my sheath. And then I tried to sing. But so dismal were the echoes, so lowering the aspect of the mighty trees, that seemed, in the quaking shadows, to be instinct with life and motion, that "The Three Cavaliers" died away at the first verse; and then, from the woods in front of us, rang out a scream for help, so shrill and sharp in its agony that it froze the blood in our veins. "'Tis a spirit!" gasped Pierrebon, with pale lips, and half pulled his horse round; but even as he did so the shriek rang out again--a woman's voice--and high and shrill in its octave of suffering. It was enough for me, and, sword in hand, I galloped for the sound. A few strides of the good beast, a leap over a fallen tree trunk, and in a wide clearing I saw before me a deed of shame. There was a man lying dead on the ground. There was a white-robed woman, screaming and struggling as two men tried to force her on to a horse; whilst another man, mounted on a white horse, with a white mask on his face, was urging them on to their work, and a long sword glittered in his hand. I stayed not for a second, but, galloping straight on, made so sudden an assault that one of the knaves was down and twisting on the grass like a snake with a broken back, and the other had fled with a howl into the forest almost before my coming was realised. But as the horse carried me on I felt a felon blow graze my cap, and I had but time to half turn and parry another when I found myself face to face with the masked man.
