The pure, mindless, exquisite motion and fluidity of the music delighted him with a strange exasperation. There was something tense, exasperated to the point of intolerable anger, in his good–humored breast, as he played the finely–spun peace–music. The more exquisite the music, the more perfectly he produced it, in sheer bliss; and at the same time, the more intense was the maddened exasperation within him.

Millicent appeared in the room. She fidgetted at the sink. The music was a bugbear to her, because it prevented her from saying what was on her own mind. At length it ended, her father was turning over the various books and sheets. She looked at him quickly, seizing her opportunity.

“Are you going out, Father?” she said.

“Eh?”

“Are you going out?” She twisted nervously.

“What do you want to know for?”

He made no other answer, and turned again to the music. His eye went down a sheet—then over it again—then more closely over it again.

“Are you?” persisted the child, balancing on one foot.

He looked at her, and his eyes were angry under knitted brows.

“What are you bothering about?” he said.

“I’m not bothering—I only wanted to know if you were going out,” she pouted, quivering to cry.

“I expect I am,” he said quietly.

She recovered at once, but still with timidity asked:

“We haven’t got any candles for the Christmas tree—shall you you buy some, because mother isn’t going out?”

“Candles!” he repeated, settling his music and taking up the piccolo.

“Yes—shall you buy us some, Father? Shall you?”

“Candles!” he repeated, putting the piccolo to his mouth and blowing a few piercing, preparatory notes.

“Yes, little Christmas–tree candles—blue ones and red ones, in boxes —Shall you, Father?”

“We’ll see—if I see any—”

“But SHALL you?” she insisted desperately. She wisely mistrusted his vagueness.

But he was looking unheeding at the music. Then suddenly the piccolo broke forth, wild, shrill, brilliant. He was playing Mozart. The child’s face went pale with anger at the sound. She turned, and went out, closing both doors behind her to shut out the noise.

The shrill, rapid movement of the piccolo music seemed to possess the air, it was useless to try to shut it out. The man went on playing to himself, measured and insistent. In the frosty evening the sound carried. People passing down the street hesitated, listening. The neighbours knew it was Aaron practising his piccolo. He was esteemed a good player: was in request at concerts and dances, also at swell balls. So the vivid piping sound tickled the darkness.

He played on till about seven o’clock; he did not want to go out too soon, in spite of the early closing of the public houses. He never went with the stream, but made a side current of his own. His wife said he was contrary. When he went into the middle room to put on his collar and tie, the two little girls were having their hair brushed, the baby was in bed, there was a hot smell of mince–pies baking in the oven.

And Holmes’s fears came to be realized, for from that day to this no word has ever been heard either of the beautiful woman, the sinister German, or the morose Englishman. Early that morning a peasant had met a cart containing several people and some very bulky boxes driving rapidly in the direction of Reading, but there all traces of the fugitives disappeared, and even Holmes’s ingenuity failed ever to discover the least clue as to their whereabouts.

The firemen had been much perturbed at the strange arrangements which they had found within, and still more so by discovering a newly severed human thumb upon a window-sill of the second floor. About sunset, however, their efforts were at last successful, and they subdued the flames, but not before the roof had fallen in, and the whole place been reduced to such absolute ruin that, save some twisted cylinders and iron piping, not a trace remained of the machinery which had cost our unfortunate acquaintance so dearly. Large masses of nickel and of tin were discovered stored in an out-house, but no coins were to be found, which may have explained the presence of those bulky boxes which have been already referred to.

How our hydraulic engineer had been conveyed from the garden to the spot where he recovered his senses might have remained forever a mystery were it not for the soft mould, which told us a very plain tale. He had evidently been carried down by two persons, one of whom had remarkably small feet and the other unusually large ones. On the whole, it was most probable that the silent Englishman, being less bold or less murderous than his companion, had assisted the woman to bear the unconscious man out of the way of danger.

“Well,” said our engineer ruefully as we took our seats to return once more to London, “it has been a pretty business for me! I have lost my thumb and I have lost a fifty-guinea fee, and what have I gained?”

“Experience,” said Holmes, laughing. “Indirectly it may be of value, you know; you have only to put it into words to gain the reputation of being excellent company for the remainder of your existence.”

The Lord St. Simon marriage, and its curious termination, have long ceased to be a subject of interest in those exalted circles in which the unfortunate bridegroom moves. Fresh scandals have eclipsed it, and their more piquant details have drawn the gossips away from this four-year-old drama. As I have reason to believe, however, that the full facts have never been revealed to the general public, and as my friend Sherlock Holmes had a considerable share in clearing the matter up, I feel that no memoir of him would be complete without some little sketch of this remarkable episode.

It was a few weeks before my own marriage, during the days when I was still sharing rooms with Holmes in Baker Street, that he came home from an afternoon stroll to find a letter on the table waiting for him. I had remained indoors all day, for the weather had taken a sudden turn to rain, with high autumnal winds, and the Jezail bullet which I had brought back in one of my limbs as a relic of my Afghan campaign throbbed with dull persistence. With my body in one easy-chair and my legs upon another, I had surrounded myself with a cloud of newspapers until at last, saturated with the news of the day, I tossed them all aside and lay listless, watching the huge crest and monogram upon the envelope upon the table and wondering lazily who my friend’s noble correspondent could be.
