He soon entered Little Bourke Street, and plunged into the labyrinth of slums, which he knew thoroughly. It was a clear, starry night, but the cool, fresh air was tainted in this locality by the foul miasma which pervaded the neighbourhood, and even the detective, accustomed as he was to the place, felt disgusted with the sickly odours that permeated the atmosphere. Ah Goon's house was in a narrow right-of-way off one of the larger alleys, and there was a faint candle burning in the window to attract customers. Pausing at the door a moment, Naball listened to hear if there was any European within. The monotonous chant of a Chinese beggar could be heard coming down the alley, and every now and then the screams of two women fighting, while occasionally a number of noisy larrikins would come tramping heavily along, forming a strong contrast to the silent, soft-footed Orientals. Pushing open the door, Naball entered the den, a small, low-ceilinged room, which was filled with a dull, smoky atmosphere. At the end was a gaudy-looking shrine, all yellow, red, and green, with tinsel flowers, and long red bills with fantastic Chinese letters on them in long rows. Candles were burning in front of this, and cast a feeble light around--on a pile of bamboo canes and baskets heaped up against the wall; on strange-looking Chinese stools of cane-work; on _bizarre_ ivory carvings set on shelves; and on a low raised platform at the end of the room, whereon the opium-smokers reclined. Above this ground-floor were two or three other broad, shallow shelves, in each of which a Chinaman was lying, sunk deep in an opium slumber; there was also a kerosene lamp on the lower floor, beside which Ah Goon was reclining, and deftly preparing a pipe of opium for a fat, stolid-looking Chinaman, who watched the process with silent apathy. Ah Goon looked up as the detective entered, and a bland smile spread over his face as he nodded to him, and went on preparing his pipe, while Naball stood watching the queer operation. There was an oil lamp with a clear flame in front of Ah Goon, who was holding a kind of darning-needle. Dipping this into a thick, brown, sticky-looking substance, contained in a small pot, he twirled the needle rapidly, spinning round the glutinous mass like treacle. Then he placed it in the flame of the lamp, and turned it slowly round and round for a short time until it was ready; then, having placed it in the small hole of the opium pipe, which he held ready in his other hand, he gave it to his countryman, who received it with a grunt of satisfaction, and, lying back, took the long stem between his lips and inhaled the smoke with long, steady breaths. When his pipe was done, which was accomplished in three or four whiffs, he devoted himself to preparing another, while Ah Goon arose to his feet to speak to Naball.
