Keith went out, his pulse quickening to the significance of the iron man's words, and wondering what the "mine" was that McDowell had promised to explode, but which he had not.

Keith lost no time in heading for Shan Tung's. He was like a man playing chess, and the moves were becoming so swift and so intricate that his mind had no rest. Each hour brought forth its fresh necessities and its new alternatives. It was McDowell who had given him his last cue, perhaps the surest and safest method of all for winning his game. The iron man, that disciple of the Law who was merciless in his demand of an eye for an eye and a tooth for a tooth, had let him understand that the world would be better off without Shan Tung. This man, who never in his life had found an excuse for the killer, now maneuvered subtly the suggestion for a killing.

Keith was both shocked and amazed. "If anything happens, let it be in the open and not on Shan Tung's premises," he had warned him. That implied in McDowell's mind a cool and calculating premeditation, the assumption that if Shan Tung was killed it would be in self-defense. And Keith's blood leaped to the thrill of it. He had not only found the depths of McDowell's personal interest in Miriam Kirkstone, but a last weapon had been placed in his hands, a weapon which he could use this day if it became necessary. Cornered, with no other hope of saving himself, he could as a last resort kill Shan Tung—and McDowell would stand behind him!

He went directly to Shan Tung's cafe and sauntered in. There were large changes in it since four years ago. The moment he passed through its screened vestibule, he felt its oriental exclusiveness, the sleek and mysterious quietness of it. One might have found such a place catering to the elite of a big city. It spoke sumptuously of a large expenditure of money, yet there was nothing bizarre or irritating to the senses. Its heavily-carved tables were almost oppressive in their solidity. Linen and silver, like Shan Tung himself, were immaculate. Magnificently embroidered screens were so cleverly arranged that one saw not all of the place at once, but caught vistas of it. The few voices that Keith heard in this pre-lunch hour were subdued, and the speakers were concealed by screens. Two orientals, as immaculate as the silver and linen, were moving about with the silence of velvet-padded lynxes. A third, far in the rear, stood motionless as one of the carven tables, smoking a cigarette and watchful as a ferret. This was Li King, Shan Tung's right-hand man.

Keith approached him. When he was near enough, Li King gave the slightest inclination to his head and took the cigarette from his mouth. Without movement or speech he registered the question, "What do you want?"

Keith knew this to be a bit of oriental guile. In his mind there was no doubt that Li King had been fully instructed by his master and that he had been expecting him, even watching for him. Convinced of this, he gave him one of Conniston's cards and said,

"Take this to Shan Tung. He is expecting me."

Li King looked at the card, studied it for a moment with apparent stupidity, and shook his head. "Shan Tung no home. Gone away."
