"Do you think she is likely to wake, Doctor?" he asked.

"I think not," I replied.

Nayland Smith stood upon the rug before the hearth, swinging from one foot to the other, in his nervously restless way. The room was foggy with the fumes of tobacco, for he, too, was smoking.

At intervals of some five to ten minutes, his blackened briar (which I never knew him to clean or sc.r.a.pe) would go out. I think Smith used more matches than any other smoker I have ever met, and he invariably carried three boxes in various pockets of his garments.

The tobacco habit is infectious, and, seating myself in an arm-chair, I lighted a cigarette. For this dreary vigil I had come prepared with a bunch of rough notes, a writing-block, and a fountain pen. I settled down to work upon my record of the Fu-Manchu case.

Silence fell upon Maple Cottage. Save for the shuddering sigh which whispered through the over-hanging cedars and Smith's eternal match-striking, nothing was there to disturb me in my task. Yet I could make little progress. Between my mind and the chapter upon which I was at work a certain sentence persistently intruded itself. It was as though an unseen hand held the written page closely before my eyes.

This was the sentence:

"Imagine a person, tall, lean, and feline, high-shouldered, with a brow like Shakespeare and a face like Satan, a close-shaven skull, and long, magnetic eyes of the true cat-green: invest him with all the cruel cunning of an entire Eastern race, acc.u.mulated in one giant intellect..."

Dr. Fu-Manchu! Fu-Manchu as Smith had described him to me on that night which now seemed so remotely distant--the night upon which I had learned of the existence of the wonderful and evil being born of that secret quickening which stirred in the womb of the yellow races.

As Smith, for the ninth or tenth time, knocked out his pipe on a bar of the grate, the cuckoo clock in the kitchen proclaimed the hour.

"Two," said James Weymouth.

I abandoned my task, replacing notes and writing-block in the bag that I had with me. Weymouth adjusted the lamp which had begun to smoke.

I tiptoed to the stairs and, stepping softly, ascended to the sick room. All was quiet, and Mrs. Weymouth whispered to me that the patient still slept soundly. I returned to find Nayland Smith pacing about the room in that state of suppressed excitement habitual with him in the approach of any crisis. At a quarter past two the breeze dropped entirely, and such a stillness reigned all about us as I could not have supposed possible so near to the ever-throbbing heart of the great metropolis. Plainly I could hear Weymouth's heavy breathing. He sat at the window and looked out into the black shadows under the cedars. Smith ceased his pacing and stood again on the rug very still.

He was listening! I doubt not we were all listening.

Some faint sound broke the impressive stillness, coming from the direction of the village street. It was a vague, indefinite disturbance, brief, and upon it ensued a silence more marked than ever.

Some minutes before, Smith had extinguished the lamp. In the darkness I heard his teeth snap sharply together.

The call of an owl sounded very clearly three times.

I knew that to mean that a messenger had come; but from whence or bearing what tidings I knew not. My friend's plans were incomprehensible to me, nor had I pressed him for any explanation of their nature, knowing him to be in that high-strung and somewhat irritable mood which claimed him at times of uncertainty--when he doubted the wisdom of his actions, the accuracy of his surmises. He gave no sign.

Very faintly I heard a clock strike the half-hour. A soft breeze stole again through the branches above. The wind I thought must be in a new quarter since I had not heard the clock before. In so lonely a spot it was difficult to believe that the bell was that of St. Paul's. Yet such was the fact.

And hard upon the ringing followed another sound--a sound we all had expected, had waited for; but at whose coming no one of us, I think, retained complete mastery of himself.

Breaking up the silence in a manner that set my heart wildly leaping it came--an imperative knocking on the door!

"My G.o.d!" groaned Weymouth--but he did not move from his position at the window.

"Stand by, Petrie!" said Smith.

He strode to the door--and threw it widely open.

I know I was very pale. I think I cried out as I fell back--retreated with clenched hands from before THAT which stood on the threshold.

It was a wild, unkempt figure, with straggling beard, hideously staring eyes. With its hands it clutched at its hair--at its chin; plucked at its mouth. No moonlight touched the features of this unearthly visitant, but scanty as was the illumination we could see the gleaming teeth--and the wildly glaring eyes.

It began to laugh--peal after peal--hideous and shrill.

Nothing so terrifying had ever smote upon my ears. I was palsied by the horror of the sound.

Then Nayland Smith pressed the b.u.t.ton of an electric torch which he carried. He directed the disk of white light fully upon the face in the doorway.

"Oh, G.o.d!" cried Weymouth. "It's John!"--and again and again: "Oh, G.o.d! Oh, G.o.d!"

Perhaps for the first time in my life I really believed (nay, I could not doubt) that a thing of another world stood before me. I am ashamed to confess the extent of the horror that came upon me. James Weymouth raised his hands, as if to thrust away from him that awful thing in the door. He was babbling--prayers, I think, but wholly incoherent.

"Hold him, Petrie!"

Smith's voice was low. (When we were past thought or intelligent action, he, dominant and cool, with that forced calm for which, a crisis over, he always paid so dearly, was thinking of the woman who slept above.)

He leaped forward; and in the instant that he grappled with the one who had knocked I knew the visitant for a man of flesh and blood--a man who shrieked and fought like a savage animal, foamed at the mouth and gnashed his teeth in horrid frenzy; knew him for a madman--knew him for the victim of Fu-Manchu--not dead, but living--for Inspector Weymouth--a maniac!

In a flash I realized all this and sprang to Smith's a.s.sistance. There was a sound of racing footsteps and the men who had been watching outside came running into the porch. A third was with them; and the five of us (for Weymouth's brother had not yet grasped the fact that a man and not a spirit shrieked and howled in our midst) clung to the infuriated madman, yet barely held our own with him.

"The syringe, Petrie!" gasped Smith. "Quick! You must manage to make an injection!"

I extricated myself and raced into the cottage for my bag. A hypodermic syringe ready charged I had brought with me at Smith's request. Even in that thrilling moment I could find time to admire the wonderful foresight of my friend, who had divined what would befall--isolated the strange, pitiful truth from the chaotic circ.u.mstances which saw us at Maple Cottage that night.

Let me not enlarge upon the end of the awful struggle. At one time I despaired (we all despaired) of quieting the poor, demented creature.

But at last it was done; and the gaunt, blood-stained savage whom we had known as Detective-Inspector Weymouth lay pa.s.sive upon the couch in his own sitting-room. A great wonder possessed my mind for the genius of the uncanny being who with the scratch of a needle had made a brave and kindly man into this unclean, brutish thing.

Nayland Smith, gaunt and wild-eyed, and trembling yet with his tremendous exertions, turned to the man whom I knew to be the messenger from Scotland Yard.

"Well?" he rapped.

"He is arrested, sir," the detective reported. "They have kept him at his chambers as you ordered."

"Has she slept through it?" said Smith to me. (I had just returned from a visit to the room above.) I nodded.

"Is HE safe for an hour or two?"--indicating the figure on the couch.

"For eight or ten," I replied grimly.

"Come, then. Our night's labors are not nearly complete."

CHAPTER x.x.x

LATER was forthcoming evidence to show that poor Weymouth had lived a wild life, in hiding among the thick bushes of the tract of land which lay between the village and the suburb on the neighboring hill.

Literally, he had returned to primitive savagery and some of his food had been that of the lower animals, though he had not scrupled to steal, as we learned when his lair was discovered.

He had hidden himself cunningly; but witnesses appeared who had seen him, in the dusk, and fled from him. They never learned that the object of their fear was Inspector John Weymouth. How, having escaped death in the Thames, he had crossed London un.o.bserved, we never knew; but his trick of knocking upon his own door at half-past two each morning (a sort of dawning of sanity mysteriously linked with old custom) will be a familiar cla.s.s of symptom to all students of alienation.

I revert to the night when Smith solved the mystery of the knocking.
