He kicked open the door with his foot and thrust the boy inside. Frank found himself standing before the embroidered curtains that were suspended across the entrance of the smoking-room. Ling lifted his great voice in a kind of shout, mingling his words with triumphant laughter.

"Ah Wu," he cried, "give welcome to a visitor who loves you. There is one here whom it will rejoice your heart to see. Come forth, old fox, and greet the mighty Ling!"

Having delivered himself thus dramatically, he flung the curtains aside, and stepped into the opium den, dragging Frank with him.

Ah Wu, as fat and crafty-looking as ever, stood in the centre of the lower room in front of the stairs that led to the balcony above.

He was holding in his hand a blue china bowl filled with samshu. And so dismayed was he when he set eyes upon his gigantic guest that the bowl fell from his hand and smashed to atoms on the floor.

"Ling!" he gasped.

"The same," roared Ling. "And this time I come not to debate and argue, to exchange words with liars. I come for Men-Ching. I have reason to believe that he is here."

Ah Wu strove to pretend he was delighted to welcome Ling. He smiled from ear to ear, his little eyes almost disappearing in the fat of his face. He bowed, folding his hands in the prescribed Chinese fashion. He even took a few steps forward, so that he was almost within reach of the long arms of the Honanese.

"Men-Ching," said he, still smiling, "is not here."

And no sooner had the words left his lips than he was given a practical and somewhat painful demonstration of the violent character of the man with whom he had to deal. Upon the right of the entrance, adorned by the embroidered curtains, was a lacquer table, upon which stood a heavy china vase. Without a word of warning, Ling seized this vase by the neck, and hurled it with all his force at the proprietor of the opium den. The ornament must have weighed several pounds, and it struck Ah Wu fair in the chest, with the result that he went over backwards and lay, stretched at his full length, at the foot of the staircase. Almost a minute elapsed before he struggled to his feet. Ling had not moved.
