It was as if Frank Armitage had been struck. He was so astonished at the sudden mention of Men-Ching's name that he caught his breath in a kind of gasp. Fortunately Ling was not looking at him at the moment. The man had drawn a long knife of Malay design from his belt, and was examining it fondly, feeling the sharpness of the blade with his thumb.

"This man," said Ling, "is over sixty years of age--old in crime, but a babe in matters of intelligence. He has a long thin beard upon his chin and his grey queue is no larger than the tail of a rat. He wears a faded scarlet coat, and limps with his left foot when he walks. Also, he rubs his hands together as if he were always pleased. Pleased!" roared Ling. "When he sets eyes upon me, the pleasure will go out of him as a candle is blown out in the draught. But, tell me, you have listened and will remember?"

Frank answered that he had paid strict attention. He did not think it incumbent upon him to advise the "mighty Ling" that he already knew Men-Ching perfectly well. He was both amazed by the coincidence and utterly bewildered as regards the business which these two could have in common. He did not dream for a moment that Ling was as dangerous to himself as the redoubtable Cheong-Chau: that he now found himself in the presence of the man who would soon hold in his great hands the trump cards in this colossal game of Death.

Ling picked up the candle, and rose to his full height.

"If I lift you up by the feet," said he, "you should be able to reach that rafter. Thence, without difficulty, you should be able to gain the man-hole, and so to the roof. From the roof you will obtain an excellent view of the harbour. The moonlight should be sufficient to enable you to see anyone who approaches. Keep your eyes open, and the moment you see the man whom I have described let me know. I will remain here."

Frank had no alternative but to obey the instructions of this extraordinary ruffian. Indeed, he was powerless as a mouse in the jaws of a cat. He was ordered to straighten himself, to remain in a position perfectly upright and rigid, and then he was lifted high above the man's head until he was within easy reach of one of the rafters. Swinging himself on to this, he gained the man-hole which had been pointed out to him, and a moment after he found himself upon the roof.

Thence--as Ling had predicted--he was able to look down upon the numerous wharves and jetties along the bank of the river. The moon was sinking low, but it was so magnified by refraction on account of the moisture in the atmosphere that the boy was able to see quite clearly, not only the various junks, wupans and sampans that lay anchored along the shore, but also the whole extent of the bund itself.

A party of coolies was already at work, and in several places there were signs of life on board the ships. Frank, looking down through the man-hole through which he had passed, could see the mighty Ling, who had taken a book from his pocket and was reading aloud by means of the candlelight. He was reading the Analects of Confucius, a volume that is admitted to contain some of the purest ethical reasoning in the world. The man read aloud in a deep voice that sounded to Frank like a roll of far distant thunder. He was obviously fully conscious of the literary and philosophic beauty of the famous maxims.

As for Frank, his thoughts were purely material. He could not think why this singular and terrible man should be so anxious to find Men-Ching. He knew, however, that it was essential that he himself should get into touch with Cheong-Chau's second-in-command. Personally, he was not in the least inclined to render assistance to Ling. But he could not deny the fact, even to himself, that he feared the man more than he had ever feared anyone before--even the giants and ogres of which, as a child, he had been wont to dream. He knew that his life was at stake, that Ling would not hesitate to kill him if, through any fault of his, Men-Ching managed to escape.

There could be no doubt that Men-Ching was at that moment in the town, probably in one of the numerous opium dens which are to be found in every Chinese city. Frank had gleaned that information, and somehow or other Ling was equally well informed. It was also certain that some time that morning Men-Ching would embark and proceed upon his journey to Canton. Frank, therefore, kept a sharp look-out for the man, but it was only fear of Ling that impelled him to do so.
