On one such occasion, when it was nearly pitch-dark, and the sound had for some time ceased, he was crouching upon a high-pitched roof of great slabs, his fingers clutched around the edges of one of them, and his mountaineering habits standing him in good stead, protected a little from the force of the blast by a huge stack of chimneys that rose to windward: while he clung thus waiting—louder than he had yet heard it, almost in his very ear, arose the musical ghost-cry—this time like that of a soul in torture. The moon came out, as at the cry, to see, but Donal could spy nothing to suggest its origin. As if disappointed, the moon instantly withdrew, the darkness again fell, and the wind rushed upon him full of keen slanting rain, as if with fierce intent of protecting the secret: there was little chance of success that night! he must break off the hunt till daylight! If there was any material factor in the sound, he would be better able to discover it then! By the great chimney-stack he could identify the spot where he had been nearest to it! There remained for the present but the task of finding his way back to his tower.

A difficult task it was—more difficult than he anticipated. He had not an idea in what direction his tower lay—had not an idea of the track, if track it could be called, by which he had come. One thing only was clear—it was somewhere else than where he was. He set out therefore, like any honest pilgrim who knows only he must go somewhere else, and began his wanderings. He found himself far more obstructed than in coming. Again and again he could go no farther in the direction he was trying, again and again had to turn and try another. It was half-an-hour at least before he came to a spot he knew, and by that time, with the rain the wind had fallen a little. Against a break in the clouds he saw the outline of one of his store-sheds, and his way was thenceforward plain. He caught up his pail, filled it with coal and wood, and hastened to his nest as quickly as cramped joints would carry him, hopeless almost of finding his fire still alive.

But when he reached the stair, and had gone down a few steps, he saw a strange sight: below him, at his door, with a small wax-taper in her hand, stood the form of a woman, in the posture of one who had just knocked, and was hearkening for an answer. So intent was she, and so loud was the wind among the roofs, that she had not heard his step, and he stood a moment afraid to speak lest he should startle her. Presently she knocked again. He made an attempt at ventriloquy, saying in a voice to sound farther off than it was, “Come in.” A hand rose to the latch, and opened the door. By the hand he knew it was lady Arctura.

“Welcome to the stormy sky, my lady!” he said, as he entered the room after her—a pleasant object after his crawling excursion!

She started a little at his voice behind her, and turning was more startled still.

Donal was more like a chimney-sweep than a tutor in a lord’s castle. He was begrimed and blackened from head to foot, and carried a pailful of coals and wood. Reading readily her look, he made haste to explain.

“I have been on the roof for the last hour,” he said.

“What were you doing there,” she asked, with a strange mingling of expressions, “in such a night?”

“I heard the music, my lady—the ghost-music, you know, that haunts the castle, and—”

“I heard it too,” she murmured, with a look almost of terror. “I have often heard it before, but never so loud as to-night. Have you any notion about it, Mr. Grant?”
