"It contained a minute quantity of the serum which I am now preparing—the serum whose discovery was the crowning achievement of a great scientist's career (I refer, Dr. Stuart, to my brilliant predecessor). They were buried alive; but no surgeon in Europe or America would have hesitated to certify them dead. Aided by a group of six Hindu fanatics, trained as Lughais (grave-diggers), it was easy to gain access to their resting-places. One had the misfortune to be cremated by his family—a great loss to my Council. But the others are now in China, at our headquarters. They are labouring day and night to bring this war-scarred world under the sceptre of an Eastern Emperor."
"Faugh!" cried Stuart. "The whole of that war-scarred world will stand armed before you!"
"We realise that, doctor; therefore we are prepared for it. We spoke of the Norwegian Henrick Ericksen. This is his most recent contribution to our armament."
Fo-Hi rested on long yellow hand upon a kind of model searchlight.
"I nearly committed the clumsy indiscretion of removing you with this little instrument," he said. "You recall the episode? Ericksen's Disintegrating Ray, Dr. Stuart. The model, here, possesses a limited range, of course, but the actual instrument has a compass of seven and a half miles. It can readily be carried by a heavy plane! One such plane in a flight from Suez to Port Said, could destroy all the shipping in the Canal and explode every grain of ammunition on either shore! Since I must leave England to-night, the model must be destroyed, and unfortunately a good collection of bacilli has already suffered the same fate."
Placidly, slowly, and unmoved from his habit of unruffled dignity, Fo-Hi placed the model in a deep mortar, whilst Stuart watched him speechless and aghast. He poured the contents of a large pan into the mortar, whereupon a loud hissing sound broke the awesome silence of the room and a cloud of fumes arose.
"Not a trace, doctor!" said the cowled man. "A little preparation of my own. It destroys the hardest known substance—with the solitary exception of a certain clay—in the same way that nitric acid would destroy tissue paper. You see I might have aspired to become famous among safe-breakers."
"You have preferred to become infamous among murderers!" snapped
Stuart.
"To murder, Dr. Stuart, I have never stooped. I am a specialist in selective warfare. When you visit the laboratory of our chief chemist in Kiangsu you will be shown the whole of the armory of the Sublime Order. I regret that the activities of your zealous and painfully inquisitive friend, M. Gaston Max, have forced me to depart from England before I had completed my work here."
"I pray you may never depart," murmured Stuart.
