"For what reason?--and why have you so suddenly changed your mind?"

"For a reason which I hope will presently become evident," he said; "and as to my change of mind, unless I am greatly mistaken, the wily old Chinaman from whom I wrested this treasure was infinitely more clever than I gave him credit for being!"

Through the open window came faintly to my ears the chiming of Big Ben.

The hour was a quarter to two. London's pulse was dimmed now, and around about us that great city slept as soundly as it ever sleeps.

Other sounds came vaguely through the fog, and beside Nayland Smith I sat and watched him at work upon the Tlun-Nr box.

Every k.n.o.b of the intricate design he pushed, pulled and twisted; but without result. The night wore on, and just before three o'clock Inspector Weymouth knocked upon the door. I admitted him, and side by side the two of us stood watching Smith patiently pursuing his task.

All conversation had ceased, when, just as the muted booming of London's clocks reached my ears again and Weymouth pulled out his watch, there came a faint click ... and I saw that Smith had raised the lid of the coffer!

Weymouth and I sprang forward with one accord, and over Smith's shoulders peered into the interior. There was a second lid of some dull, black wood, apparently of great age, and fastened to it so as to form k.n.o.bs or handles was an exquisitely carved pair of _golden pomegranates!_

"They are to raise the wooden lid, Mr. Smith!" cried Weymouth eagerly.

"Look! there is a hollow in each to accommodate the fingers!"

"Aren't you going to open it?" I demanded excitedly--"aren't you going to open it?"

"Might I invite you to accompany me into the bedroom yonder for a moment?" he replied in a tome of studied reserve. "You also, Weymouth?"

Smith leading, we entered the room where the dead man lay stretched upon the bed.

"Note the appearance of his fingers," directed Nayland Smith.

I examined the peculiarity to which Smith had drawn my attention. The dead man's fingers were swollen extraordinarily, the index finger of either hand especially being oddly discolored, as though bruised from the nail upward. I looked again at the ghastly face, then, repressing a shudder, for the sight was one not good to look upon, I turned to Smith, who was watching me expectantly with his keen, steely eyes.

From his pocket the took out a knife containing a number of implements, amongst them a hook-like contrivance.

"Have you a b.u.t.ton-hook, Petrie," he asked, "or anything of that nature?"

"How will this do?" said the Inspector, and he produced a pair of handcuffs. "They were not wanted," he added significantly.

"Better still," declared Smith.

Reclosing his knife, he took the handcuffs from Weymouth, and, returning to the sitting-room, opened them widely and inserted two steel points in the hollows of the golden pomegranates. He pulled.

There was a faint sound of moving mechanism and the wooden lid lifted, revealing the interior of the coffer. It contained three long bars of lead--and nothing else!

Supporting the lid with the handcuffs--

"Just pull the light over here, Petrie," said Smith.

I did as he directed.

"Look into these two cavities where one is expected to thrust one's fingers!"

Weymouth and I craned forward so that our heads came into contact.

"My G.o.d!" whispered the Inspector, "we know now what killed him!"

Visible, in either little cavity against the edge of the steel handcuff, was the point of a needle, which evidently worked in an exquisitely made socket through which the action of raising the lid caused it to protrude. Underneath the lid, midway between the two pomegranates, as I saw by slowly moving the lamp, was a little receptacle of metal communicating with the base of the hollow needles.

The action of lifting the lid not only protruded the points but also operated the hypodermic syringe!

"Note," snapped Smith--but his voice was slightly hoa.r.s.e.

He removed the points of the bracelets. The box immediately reclosed with no other sound than a faint click.

"G.o.d forgive him," said Smith, glancing toward the other room, "for he died in my stead!--and Dr. Fu-Manchu scores an undeserved failure!"

CHAPTER XV

ZARMI REAPPEARS

"Come in!" I cried.

The door opened and a page-boy entered.

"A cable for Dr. Petrie."

I started up from my chair. A thousand possibilities--some of a sort to bring dread to my heart--instantly occurred to me. I tore open the envelope and, as one does, glanced first at the name of the sender.

It was signed "Karamaneh!"

"Smith!" I said hoa.r.s.ely, glancing over the ma.s.sage, "Karamaneh is on her way to England. She arrives by the _Nicobar_ to-morrow!"

"Eh?" cried Nayland Smith, in turn leaping to his feet. "She had no right to come alone, unless----"

The boy, open-mouthed, was listening to our conversation, and I hastily thrust a coin into his hand and dismissed him. As the door closed--

"Unless what, Smith?" I said, looking my friend squarely in the eyes.

"Unless she has learnt something, or--is flying away from some one!"

My mind set in a whirl of hopes and fears, longings and dreads.

"What do you mean, Smith?" I asked. "This is the place of danger, as we know to our cost; she was safe in Egypt."

Nayland Smith commenced one of his restless perambulations, glancing at me from time to time and frequently tugging at the lobe of his ear.

"_Was_ she safe in Egypt?" he rapped. "We are dealing, remember, with the Si-Fan, which, if I am not mistaken, is a sort of Eleusinian Mystery holding some kind of dominion over the eastern mind, and boasting initiates throughout the Orient. It is almost certain that there is an Egyptian branch, or group--call it what you will--of the d.a.m.nable organization."

"But Dr. Fu-Manchu----"

"Dr. Fu-Manchu--for he lives, Petrie! my own eyes bear witness to the fact--Dr. Fu-Manchu is a sort of delegate from the headquarters. His prodigious genius will readily enable him to keep in touch with every branch of the movement, East and West."
