Another blow was heard, louder than before. Those who were nearest crept farther from the entrance; but Norton, as though bent on some wild exploit, approached the door. He raised the latch, and, as it swung slowly back, most of the party beheld a figure on horseback, motionless before the opening. From the height they occupied this mysterious visitor was depicted in a clear bold outline against a mass of red angry-looking clouds, towards the south-east, on the edge of which hung the broad disc of the moon breaking through "Alps" of clouds, her calm sweet glance fast dissipating the wrath that yet lowered on the brow of Heaven. The intruder wore a dark-coloured vestment; a low-crowned hat surmounted his figure. His steed was black and heavily built. Probably, from the position whence he was seen, both horse and rider looked almost gigantic. Not a word was spoken. The stranger stood apparently immovable, like some huge equestrian statue, in the dim and mystic twilight. Norton's two friends were evidently astonished and alarmed, but he scarcely evinced any surprise; some superior and unknown source of excitement overpowered the fear he might otherwise have felt. Silence continued for a few moments, the strange figure remaining perfectly still. Pilkington approached nearer to his friend, who was yet standing near the threshold, gazing intently on the vision before him. He whispered a few words over Norton's shoulder. "Knowest thou this stranger, Norton?" "Yes," he replied with great earnestness and solemnity; "years have gone by since I saw him. Thou never knewest mine uncle; but that is he, or one sense hath turned traitor to the rest. This very night, twelve years ago--it was just before I left home for school"----His voice now became inaudible to his friend, who observed him, after a gaze of inquiry on the stranger, suddenly disappear through the opening. The door was immediately closed by a loud and violent gust. Flying open again with the rebound, the figure of Norton was seen rapidly descending the hill towards the south-east, preceded by the mysterious horseman. The light was too feeble for enabling them to ascertain the course they took; but it seemed probable that Norton was away over the hills with the unknown messenger. Their first impulse was to follow; but the impossibility of overtaking the fugitives, and the near approach of night, would have rendered it a vain and probably a perilous attempt. Looking anxiously down the dark ravine where Norton had so strangely disappeared, Pilkington was startled by a voice from behind; turning, he saw it was the man who had previously dropped those mysterious hints about the "Spectre Horseman," which now vividly recurred to his memory and imagination. "Master," said this personage, respectfully touching his cap, "you had better not follow."
