something must have warned us. For suddenly, with one accord, we three turned upon the bed, and stared out into the room from which the fog wreaths floated in.

Beeton stood nearest to the door, but, although he turned, he did not go out, but with a smothered cry crouched back against the bed. Smith it was who moved first, then I followed, and close upon his heels burst into the disordered sitting-room. The outer door had been closed but not bolted, and what with the tinted light, diffused through the silken Japanese shade, and the presence of fog in the room, I was almost tempted to believe myself the victim of a delusion. What I saw or thought I saw was this:—

A tall screen stood immediately inside the door, and around its end, like some materialization of the choking mist, glided a lithe, yellow figure, a slim, crouching figure, wearing a sort of loose robe. An impression I had of jet-black hair, protruding from beneath a little cap, of finely chiseled features and great, luminous eyes, then, with no sound to tell of a door opened or shut, the apparition was gone.

"You saw him, Petrie!—you saw him!" cried Smith.

In three bounds he was across the room, had tossed the screen aside and thrown open the door. Out he sprang into the yellow haze of the corridor, tripped, and, uttering a cry of pain, fell sprawling upon the marble floor. Hot with apprehension I joined him, but he looked up with a wry smile and began furiously rubbing his left shin.

"A queer trick, Petrie," he said, rising to his feet; "but nevertheless effective."

He pointed to the object which had occasioned his fall. It was a small metal chest, evidently of very considerable weight, and it stood immediately outside the door of Number 14a.

"That was what he came for, sir! That was what he came for! You were too quick for him!"

Beeton stood behind us, his horror-bright eyes fixed upon the box.

"Eh?" rapped Smith, turning upon him.

"That's what Sir Gregory brought to England," the man ran on almost hysterically; "that's what he's been guarding this past two weeks, night and day, crouching over it with a loaded pistol. That's what cost him his life, sir. He's had no peace, day or night, since he got it…."

We were inside the room again now, Smith bearing the coffer in his arms, and still the man ran on:

"He's never slept for more than an hour at a time, that I know of, for weeks past. Since the day we came here he hasn't spoken to another living soul, and he's lain there on the floor at night with his head on that brass box, and sat watching over it all day."

"'Beeton!' he'd cry out, perhaps in the middle of the night—'Beeton— do you hear that damned woman!' But although I'd begun to think I could hear something, I believe it was the constant strain working on my nerves and nothing else at all.

"Then he was always listening out for some one he called 'the man with the limp.' Five and six times a night he'd have me up to listen with him. 'There he goes, Beeton!' he'd whisper, crouching with his ear pressed flat to the door. 'Do you hear him dragging himself along?'

"God knows how I've stood it as I have; for I've known no peace since we left China. Once we got here I thought it would be better, but it's been worse.

"Gentlemen have come (from the India Office, I believe), but he would not see them. Said he would see no one but Mr. Nayland Smith. He had never lain in his bed until to-night, but what with taking no proper food nor sleep, and some secret trouble that was killing him by inches, he collapsed altogether a while ago, and I carried him in and laid him on the bed as I told you. Now he's dead—now he's dead."

Beeton leant up against the mantelpiece and buried his face in his hands, whilst his shoulders shook convulsively. He had evidently been greatly attached to his master, and I found something very pathetic in this breakdown of a physically strong man. Smith laid his hands upon his shoulders.

"You have passed through a very trying ordeal," he said, "and no man could have done his duty better; but forces beyond your control have proved too strong for you. I am Nayland Smith."

The man spun around with a surprising expression of relief upon his pale face.

"So that whatever can be done," continued my friend, "to carry out your master's wishes, will be done now. Rely upon it. Go into your room and lie down until we call you."

"Thank you, sir, and thank God you are here," said Beeton dazedly, and with one hand raised to his head he went, obediently, to the smaller bedroom and disappeared within.

"Now, Petrie," rapped Smith, glancing around the littered floor, "since I am empowered to deal with this matter as I see fit, and since you are a medical man, we can devote the next half-hour, at any rate, to a strictly confidential inquiry into this most perplexing case. I propose that you examine the body for any evidences that may assist you determining the cause of death, whilst I make a few inquiries here."

I nodded, without speaking, and went into the bedroom. It contained not one solitary item of the dead man's belongings, and in every way bore out Beeton's statement that Sir Gregory had never inhabited it. I bent over Hale, as he lay fully dressed upon the bed.

Saving the singularity of the symptom which had immediately preceded death—viz., the paralysis of the muscles of articulation—I should have felt disposed to ascribe his end to sheer inanition; and a cursory examination brought to light nothing contradictory to that view. Not being prepared to proceed further in the matter at the moment I was about to rejoin Smith, whom I could hear rummaging about amongst the litter of the outer room, when I made a curious discovery.

Lying in a fold of the disordered bed linen were a few petals of some kind of blossom, three of them still attached to a fragment of slender stalk.

I collected the tiny petals, mechanically, and held them in the palm of my hand studying them for some moments before the mystery of their presence there became fully appreciable to me. Then I began to wonder. The petals (which I was disposed to class as belonging to some species of Curcas or Physic Nut), though bruised, were fresh, and therefore could not have been in the room for many hours. How had they been introduced, and by whom? Above all, what could their presence there at that time portend?

"Smith," I called, and walked towards the door carrying the mysterious fragments in my palm. "Look what I have found upon the bed."

Nayland Smith, who was bending over an open despatch case which he had placed upon a chair, turned—and his glance fell upon the petals and tiny piece of stem.

I think I have never seen so sudden a change of expression take place in the face of any man. Even in that imperfect light I saw him blanch. I saw a hard glitter come into his eyes. He spoke, evenly, but hoarsely:

"Put those things down——there, on the table; anywhere."

I obeyed him without demur; for something in his manner had chilled me with foreboding.

"You did not break that stalk?"

"No. I found it as you see it."

"Have you smelled the petals?"

I shook my head. Thereupon, having his eyes fixed upon me with the strangest expression in their gray depths, Nayland Smith said a singular thing.

"Pronounce, slowly, the words Sâkya Mûni,'" he directed.

I stared at him, scarce crediting my senses; but——

"I mean
