Smith's nerves are overwrought and he was awakened by some disturbing dream. You can return to bed, Mrs. Newsome."

Nayland Smith seemed to experience much difficulty in swallowing the contents of the tumbler which I held to his lips; and, from the way in which he fingered the swollen glands, I could see that his throat, which I had vigorously ma.s.saged, was occasioning him great pain. But the danger was past, and already that gla.s.sy look was disappearing from his eyes, nor did they protrude so unnaturally.

"G.o.d, Petrie!" he whispered, "that was a near shave! I haven't the strength of a kitten!"

"The weakness will pa.s.s off," I replied; "there will be no collapse, now. A little more fresh air...."

I stood up, glancing at the windows, then back at Smith, who forced a wry smile in answer to my look.

"Couldn't be done, Petrie," he said huskily.

His words referred to the state of the windows. Although the night was oppressively hot, these were only opened some four inches at top and bottom. Farther opening was impossible because of iron brackets screwed firmly into the cas.e.m.e.nts, which prevented the windows being raised or lowered farther.

It was a precaution adopted after long experience of the servants of Dr. Fu-Manchu.

Now, as I stood looking from the half-strangled man upon the bed to those screwed-up windows, the fact came home to my mind that this precaution had proved futile. I thought of the thing which I had likened to a feather boa; and I looked at the swollen weals made by clutching fingers upon the throat of Nayland Smith.

The bed stood fully four feet from the nearest window.

I suppose the question was written in my face; for, as I turned again to Smith, who, having struggled upright, was still fingering his injured throat ruefully--"G.o.d only knows, Petrie!" he said; "no human arm could have reached me...."

For us, the night was ended so far as sleep was concerned. Arrayed in his dressing-gown, Smith sat in the white cane chair in my study with a gla.s.s of brandy and water beside him, and (despite my official prohibition) with the cracked briar, which had sent up its incense in many strange and dark places of the East and which yet survived to perfume these prosy rooms in suburban London, between his teeth. I stood with my elbow resting upon the mantelpiece looking down at him where he sat.

"By G.o.d! Petrie," he said, yet again, with his fingers straying gently over the surface of his throat, "that was a narrow shave--a d.a.m.ned narrow shave!"

"Narrower than perhaps you appreciate, old man," I replied. "You were a most unusual shade of blue when I found you...."

"I managed," said Smith evenly, "to tear those clutching fingers away for a moment and to give a cry for help. It was only for a moment, though. Petrie! they were fingers of steel--of steel!"

"The bed...." I began.

"I know that," rapped Smith. "I shouldn't have been sleeping in it, had it been within reach of the window; but, knowing that the Doctor avoids noisy methods, I had thought myself fairly safe so long as I made it impossible for any one actually to enter the room...."

"I have always insisted, Smith," I cried, "that there was danger! What of poisoned darts? What of the d.a.m.nable reptiles and insects which form part of the armoury of Fu-Manchu?"

"Familiarity breeds contempt, I suppose," he replied. "But as it happened, none of those agents was employed. The very menace that I sought to avoid reached me somehow. It would almost seem that Dr.

Fu-Manchu deliberately accepted the challenge of those screwed up windows! Hang it all, Petrie! one cannot sleep in a room hermetically sealed in weather like this! It's positively Burmese; and although I can stand tropical heat, curiously enough the heat of London gets me down almost immediately."

"The humidity; that's easily understood. But you'll have to put up with it in the future. After nightfall our windows must be closed entirely, Smith."

Nayland Smith knocked out his pipe upon the side of the fireplace. The bowl sizzled furiously, but without delay he stuffed broad-cut mixture into the hot pipe, dropping a liberal quant.i.ty upon the carpet during the process. He raised his eyes to me, and his face was very grim.

"Petrie," he said, striking a match on the heel of his slipper, "the resources of Dr. Fu-Manchu are by no means exhausted. Before we quit this room it is up to us to come to a decision upon a certain point."

He got his pipe well alight. "What kind of thing, what unnatural, distorted creature, laid hands upon my throat to-night? I owe my life, primarily, to you, old man, but secondarily, to the fact that I was awakened, just before the attack, by the creature's _coughing_--by its vile, high pitched _coughing_...."

I glanced around at the books upon my shelves. Often enough, following some outrage by the brilliant, Chinese doctor whose genius was directed to the discovery of new and unique death agents, we had obtained a clue in those works of a scientific nature which bulk largely in the library of a medical man. There are creatures, there are drugs, which, ordinarily innocuous, may be so employed as to become inimical to human life; and in the distorting of nature, in the disturbing of balances and the diverting of beneficent forces into strange and dangerous channels, Dr. Fu-Manchu excelled. I had known him to enlarge, by artificial culture, a minute species of fungus so as to render it a powerful agent capable of attacking man; his knowledge of venomous insects has probably never been paralleled in the history of the world; whilst, in the sphere of pure toxicology, he had, and has, no rival: the Borgias were children by comparison. But, look where I would, think how I might, no adequate explanation of this latest outrage seemed possible along normal lines.

"There's the clue," said Nayland Smith, pointing to a little ash-tray upon the table near by. "Follow it if you can."

But I could not.

"As I have explained," continued my friend, "I was awakened by a sound of coughing; then came a death grip on my throat, and instinctively my hands shot out in search of my attacker. I could not reach him; my hands came in contact with nothing palpable. Therefore I clutched at the fingers which were dug into my windpipe, and found them to be small--as the marks show--and _hairy_. I managed to give that first cry for help, and with all my strength I tried to unfasten the grip that was throttling the life out of me. At last I contrived to move one of the hands, and I called out again, though not so loudly. Then both the hands were back again; I was weakening; but I clawed like a madman at the thin, hairy arms of the strangling thing, and with a blood-red mist dancing before my eyes, I seemed to be whirling madly round and round until all became a blank. Evidently I used my nails pretty freely--and there's the trophy."

For the twentieth time, I should think, I raised the ash-tray in my hand and held it immediately under the table lamp in order to examine its contents. In the little bra.s.s bowl lay a blood-stained fragment of greyish hair attached to a tatter of skin. This fragment of epidermis had an odd bluish tinge, and the attached hair was much darker at the roots than elsewhere. Saving its singular colour, it might have been torn from the forearm of a very hirsute human; but although my thoughts wandered, unfettered, north, south, east and west; although, knowing the resources of Fu-Manchu, I considered all the recognized Mongolian types, and, in quest of hirsute mankind, even roamed, far north among the blubber-eating Esquimaux; although I glanced at Australasia, at Central Africa, and pa.s.sed in mental review the dark places of the Congo, nowhere in the known world, nowhere in the history of the human species, could I come upon a type of man answering to the description suggested by our strange clue.

Nayland Smith was watching me curiously as I bent over the little bra.s.s ash-tray.

"You are puzzled," he rapped in his short way. "So am I--utterly puzzled. Fu-Manchu's gallery of monstrosities clearly has become reinforced; for even if we identified the type, we should not be in sight of our explanation."

"You mean--" I began.

"Fully four feet from the window, Petrie, and that window but a few inches open! Look"--he bent forward, resting his chest against the table, and stretched out his hand towards me--"you have a rule there; just measure."

Setting down the ash-tray, I opened out the rule and measured the distance from the farther edge of the table to the tips of Smith's fingers.

"Twenty-eight inches--and _I_ have a long reach!" snapped Smith, withdrawing his arm and striking a match to relight his pipe. "There's one thing, Petrie, often proposed before, which now we must do without delay. The ivy must be stripped from the walls at the back. It's a pity, but we cannot afford to sacrifice our lives to our sense of the aesthetic. What do you make of the sound like the cracking of a whip?"

"I make nothing of it, Smith," I replied wearily. "It might have been a thick branch of ivy breaking beneath the weight of a climber."

"Did it sound like it?"

"I must confess that the explanation does not convince me, but I have no better one."

Smith, permitting his pipe to go out, sat staring straightly before him, and tugging at the lobe of his left ear.

"The old bewilderment is seizing me," I continued. "At first, when I realized that Dr. Fu-Manchu was back in England, when I realized that an elaborate murder-machine was set up somewhere in London, it seemed unreal, fantastical. Then I met--Karamaneh! She, whom we thought to be his victim, showed herself again to be his slave. Now, with Weymouth and Scotland Yard at work, the old secret evil is established again in our midst, unaccountably--our lives are menaced--sleep is a danger--every shadow threatens death ... oh! it is awful."

Smith remained silent; he did not seem to have heard my words. I knew these moods and had learnt that it was useless to seek to interrupt them. With his brows drawn down, and his deep-set eyes staring into s.p.a.ce, he sat there gripping his cold pipe so tightly that my own jaw muscles ached sympathetically. No man was better equipped than this gaunt British Commissioner to stand between society and the menace of the Yellow Doctor; I respected his meditations, for, unlike my own, they were informed by an intimate knowledge of the dark and secret things of the East, of that mysterious East out of which Fu-Manchu came, of that jungle of noxious things whose miasma had been wafted Westward with the implacable Chinaman.

I walked quietly from the room, occupied with my own bitter reflections.

CHAPTER XV

BEWITCHMENT

"You say you have two pieces of news for me?" said Nayland Smith, looking across the breakfast table to where Inspector Weymouth sat sipping coffee.

"There are two points--yes," replied the Scotland Yard man, whilst Smith paused, egg-spoon in hand, and fixed his keen eyes upon the speaker. "The first is this: the headquarters of the yellow group is no longer in the East End."

"How can you be sure of that?"

"For two reasons. In the first place, that district must now be too hot to hold Dr. Fu-Manchu; in the second place, we have just completed a house-to-house inquiry which has scarcely overlooked a rathole or a rat. That place where you say Fu-Manchu was visited by some Chinese mandarin; where you, Mr. Smith, and"--glancing in my direction--"you, doctor, were confined for a time--"

"Yes?" snapped Smith, attacking his egg.
