As he caught sight of the Madagascan he stopped short and put his hand to his head with a gesture of perplexity, striving piteously to place the stranger. He could not succeed. With a half-running, half-stumbling gait he withdrew to a corner of the room and furtively watched the two Madagascans.

There came the sound of a gong. A panel slid back, and into the room there majestically swept a Chinaman of pure Mongolian type.

He was gorgeously clad in flowing silks and wore the princely cap with a button. At a glance his piercing eye took in every detail of the room. Then he went directly to the Madagascan, whose overbearing air of assurance immediately forsook him at the Chinaman's approach.

He bowed low and reverently, for it was Long Fang to whom he made obeisance, Long Fang, leader of a great Tong, and implacable foe to all others, a Chinese whose tentacles of power reached into every corner of the underworld, spreading terror.

In an incisive, icy voice that sent a chill through the big man's frame, he now spoke.

"You have been overlong on your journey and we have been waiting for you." Then with a menace in his voice he snarled, "It is well for you that you came at last."

The big man shuddered and remained silent. Long Fang crossed to Doctor Q.

"The instrument of torture is here," he said. "The Madagascan has just brought it. He is an unrivaled strangler."

"Let him approach," commanded Doctor Q.

Long Fang beckoned, and the Strangler came forward. His eyes had been fixed on the Chinese, but now they roved to the figure of Doctor Q, and he fell back in consternation, clutching the other Madagascan by the shoulder and gasping in awestruck tones.
