Nicholas looked suspiciously at the stranger, who calmly handed him the paper; the latter’s face showed neither interest nor triumph. The deed was very simply worded: “I, Nicholas Verkloep, promise to owe unfailing and unquestioning obedience in all things to Marcus Lemoinne for the space of ten years from this day and hour, in return for the success of my organ at the end of that time, and for all the help he may give me in the interval.” The date was already filled in, being the day on which the above conversation took place, and the hour was marked two hours after noon. Nicholas glanced at the clock behind him in the chapel; the hands pointed to ten minutes to that hour. The stranger followed his glance, quietly rose from the bench, and turning his back upon him, knelt down on the narrow board fixed for this purpose to the front of the tribune.

Nicholas quickly turned things over in his mind: as to his silence about it when the promise was signed he had decided; as to his fulfilment of his obligations to the letter he was as loyally certain; as to the individual whom this man either was or represented he had very little doubt. Very few in his time would have thought otherwise; perhaps few would have hesitated so much after having made up their minds not to ask the advice of any one either before or after the contract was made. Nicholas was only an average Christian, and had no strong feelings except on the subject of his art; everything was in favor of his giving ten years’ life for the success of his scheme. As the clock struck the hour the stranger rose, touched his shoulder, and said, “Well?”

Nicholas, with something like a start, took the pen and signed his name as quickly as he could, whereupon the other also wrote in a fair and scholarly hand these words: “I, Marcus Lemoinne, promise to ensure the success of Nicholas Verkloep’s organ at the end of ten years, in return for his obedience to me during that time.”

No commonplaces passed at parting, and Nicholas went home soon after. His old master noticed that he was a little more excited than usual, and began to make plans and preparations with more energy, but he was used to these phases of mind. The young man (he was now twenty-three) procured beautiful and costly wood for carving, besides ivory, paints, and other materials, and set to work on a complete model. Now began the oddest experiences of his life: his mind seemed doubled, for he was conscious of a never-ceasing expectation, an alertness, and a watchfulness hitherto unknown to him. In the streets, in church, in bed at night, he was always looking for Lemoinne or ready to obey his summons, yet his attention, when he bestowed it on his work, was not disturbed or lessened by this parallel current of thought. His mind grew stronger, brighter, quicker, more ingenious; his fanatical devotion to his art increased daily, and with it his powers, until his fame grew to be just such as the stranger had foretold. This stimulated him further, and he made unheard-of progress, so that his old friend and teacher was half-crazy with joy and pride. The count sent for him to play in the hall before his guests on a small organ of no great power or value, and Nicholas drew from it such sounds as the great men of the profession could not draw from the most magnificent church instruments. That they were jealous of him he knew, but he feared no jealousy, as he courted no admiration. He refused repeatedly to take advantage of his reputation and increase his fortune by travelling to the various art-loving cities of the Netherlands and of Italy, or even by performing in public on great occasions, so that the crowds of his persistent admirers had to content themselves with hearing him at his own old organ in the Stromwael chapel. Even the popular preachers of the day were envious of him. Meanwhile, he worked first at the model, then at the separate pieces of his future organ. The count had given no permission, nor hinted at any, and Lemoinne had made no call on his time, but his belief in the efficacy of the bond never flagged for a moment. It did not occur to him to wonder why he never heard the man’s name mentioned as among those who, whether merchants, artists, or statesmen, had public or secret power; his unspoken suspicion of his identity prevented all such ideas, but it did strike him as odd that for ten months after the signing of the contract nothing was required of him. He felt morbidly that he did not belong to himself, and knew that, do what he would, a secret influence sat within, master of his heart and will, master even of his dreams, and, he feared, of his art also. Was it himself that he put forth in his compositions? When the ten years were ended he would be able to tell, but it was a long time to look forward to. Yet during that time his fame would have been made, and if his power then suddenly deserted him and his suspicions came to be confirmed, he could easily retire on his former laurels and compose no more. Retire at thirty-three? Well, there was the monastery; many men had made a second career, more creditable even than the first, by devoting their worldly gifts, their wealth, and their fame to religious purposes when circumstances made the world distasteful to them at an earlier period than usual. If his suspicions should be true, an after-life of atonement would be fitting, and it would give him time for studies which he longed to undertake, but had no leisure or opportunity for at present. The spiritual element counted for nothing in his calculations; there were many doors still closed in his nature. As he wandered in fancy, his fingers worked and produced beautiful or weird things. The face of Lemoinne, so constantly present to his mind, often came out in wood under his touch, and always, when finished, gave him a start of surprise; for, surely, that was not the expression he remembered? And yet, in carving the likeness, he must have had the recollection before him? A year after the interview in the chapel his old teacher the organist died, and the first strange thing that he had ever said to his pupil he said on his death-bed.

“My son,” he began, as he lay with his hand in that of Nicholas, “there is one thing I feel I must say to you before I go; it is my duty, and young men sometimes forget it. With you it is more dangerous than with most. Be your own master; do not lose the ownership of yourself. Men who do generally commit crime, and, if the slavery be to a woman, they often do base, mean things. I have sometimes feared that you were losing the mastery of yourself, and yet at other times I saw you absorbed in what has been your only idol for twelve years or more.”

“There is no woman that shares that idolatry,” answered Nicholas evasively, starting at the old man’s anxious looks and awakened insight.

“Well,” said the dying man, “I do not grudge you a wife, but I fear any one, man or woman, whose influence over you is not entirely supported and controlled by reason. In God’s name, Nicholas, and as a dying man, I beseech you, if you are in any toils, break through them as quickly as you can.”

“My dear master,” said his pupil, “when you are in heaven pray that I may be guided aright, for I shall have lost the only guide on earth whose help or advice was of use to me.”

“That is no answer, Nicholas,” said the old man reproachfully and wearily; “but remember what I said.”

“Yes, I will remember it,” said the other in an altered tone, “and, if I can, I will heed it.”
