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 buy some, because mother isn’t going out?”

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

I groaned, for I was newly come back from a weary day.

We heard the door open, a few hurried words, and then quick steps upon the linoleum. Our own door flew open, and a lady, clad in some dark-coloured stuff, with a black veil, entered the room.

“You will excuse my calling so late,” she began, and then, suddenly losing her self-control, she ran forward, threw her arms about my wife’s neck, and sobbed upon her shoulder. “Oh, I’m in such trouble!” she cried; “I do so want a little help.”

“Why,” said my wife, pulling up her veil, “it is Kate Whitney. How you startled me, Kate! I had not an idea who you were when you came in.”

“I didn’t know what to do, so I came straight to you.” That was always the way. Folk who were in grief came to my wife like birds to a light-house.

“It was very sweet of you to come. Now, you must have some wine and water, and sit here comfortably and tell us all about it. Or should you rather that I sent James off to bed?”

“Oh, no, no! I want the doctor’s advice and help, too. It’s about Isa. He has not been home for two days. I am so frightened about him!”

It was not the first time that she had spoken to us of her husband’s trouble, to me as a doctor, to my wife as an old friend and school companion. We soothed and comforted her by such words as we could find. Did she know where her husband was? Was it possible that we could bring him back to her?

It seems that it was. She had the surest information that of late he had, when the fit was on him, made use of an opium den in the farthest east of the City. Hitherto his orgies had always been confined to one day, and he had come back, twitching and shattered, in the evening. But now the spell had been upon him eight-and-forty hours, and he lay there, doubtless among the dregs of the docks, breathing in the poison or sleeping off the effects. There he was to be found, she was sure of it, at the Bar of Gold, in Upper Swandam Lane. But what was she to do? How could she, a young and timid woman, make her way into such a place and pluck her husband out from among the ruffians who surrounded him?

There was the case, and of course there was but one way out of it. Might I not escort her to this place? And then, as a second thought, why should she come at all? I was Isa Whitney’s medical adviser, and as such I had influence over him. I could manage it better if I were alone. I promised her on my word that I would send him home in a cab within two hours if he were indeed at the address which she had given me. And so in ten minutes I had left my armchair and cheery sitting-room behind me, and was speeding eastward in a hansom on a strange errand, as it seemed to me at the time, though the future only could show how strange it was to be.

But there was no great difficulty in the first stage of my adventure. Upper Swandam Lane is a vile alley lurking behind the high wharves which line the north side of the river to the east of London Bridge. Between a slop-shop and a gin-shop, approached by a steep flight of steps leading down to a black gap like the mouth of a cave, I found the den of which I was in search. Ordering my cab to wait, I passed down the steps, worn hollow in the centre by the ceaseless tread of drunken feet; and by the light of a flickering oil-lamp above the door I found the latch and made my way into a long, low room, thick and heavy with the brown opium smoke, and terraced with wooden berths, like the forecastle of an emigrant ship.
