"You do not understand—yet you are a doctor.
You do not understand—"
She stopped, moaning to herself and looking from the handsome face of the boy to me.
It was pitiful; it was uncanny.
But sorrow for the girl predominated in my mind.
Then from somewhere I heard a sound which I had heard before in houses occupied by Dr. Fu-Manchu—that of a muffled gong.
"Quick!"
Karamaneh had me by the arm.
"Up!
He has returned!"
She fled up the stairs to the balcony, I close at her heels.
The shadows veiled us, the thick carpet deadened the sound of our tread, or certainly we must have been detected by the man who entered the room we had just quitted.
It was Dr. Fu-Manchu!
Yellow-robed, immobile, the inhuman green eyes glittering catlike even, it seemed, before the light struck them, he threaded his way through the archipelago of cushions and bent over the couch of Aziz.
Karamaneh dragged me down on to my knees.
"Watch!" she whispered.
"Watch!"
Dr. Fu-Manchu felt for the pulse of the boy whom a moment since I had pronounced dead, and, stepping to the tall glass case, took out a long-necked flask of chased gold, and from it, into a graduated glass, he poured some drops of an amber liquid wholly unfamiliar to me.
I watched him with all my eyes, and noted how high the liquid rose in the measure.
He charged a needle-syringe, and, bending again over Aziz, made an injection.
Then all the wonders I had heard of this man became possible, and with an awe which any other physician who had examined Aziz must have felt, I admitted him a miracle-worker.
For as I watched, all but breathless, the dead came to life!
The glow of health crept upon the olive cheek—the boy moved—he raised his hands above his head—he sat up, supported by the Chinese doctor!
Fu-Manchu touched some hidden bell.
A hideous yellow man with a scarred face entered, carrying a tray upon which were a bowl containing some steaming fluid, apparently soup, what looked like oaten cakes, and a flask of red wine.
As the boy, exhibiting no more unusual symptoms than if he had just awakened from a normal sleep, commenced his repast, Karamaneh drew me gently along the passage into the room which we had first entered.
My heart leaped wildly as the marmoset bounded past us to drop hand over hand to the lower apartment in search of its master.
"You see," said Karamaneh, her voice quivering, "he is not dead!
But without Fu-Manchu he is dead to me.
How can I leave him when he holds the life of Aziz in his hand?"
"You must get me that flask, or some of its contents," I directed.
"But tell me, how does he produce the appearance of death?"
"I cannot tell you," she replied.
"I do not know.
It is something in the wine.
In another hour Aziz will be again as you saw him.
But see."
And, opening a little ebony box, she produced a phial half filled with the amber liquid.
"Good!" I said, and slipped it into my pocket.
"When will be the best time to seize Fu-Manchu and to restore your brother?"
"I will let you know," she whispered, and, opening the door, pushed me hurriedly from the room.
"He is going away to-night to the north; but you must not come to-night.
Quick!
Quick!
Along the passage.
He may call me at any moment."
So, with the phial in my pocket containing a potent preparation unknown to Western science, and with a last long look into the eyes of Karamaneh, I passed out into the narrow alley, out from the fragrant perfumes of that mystery house into the place of Thames-side stenches.

"WE must arrange for the house to be raided without delay," said Smith.
"This time we are sure of our ally—"
