aided my friend's laboured respirations by the usual means, setting
to work vigorously; so that presently he began to clutch at his
inflamed throat which that murderous pressure had threatened to close.

I could hear sounds of movements about the house, showing that not I
alone had been awakened by those hoarse screams.

"It's all right, old man," I said, bending over him: "brace up!"

He opened his eyes--they looked bleared and bloodshot--and gave me a
quick glance of recognition.

"It's all right, Smith!" I said--"no! don't sit up; lie there for a
moment."

I ran across to the dressing-table, whereon I perceived his flask to
lie, and mixed him a weak stimulant with which I returned to the bed.

As I bent over him again, my housekeeper appeared in the doorway, pale
and wide-eyed.

"There is no occasion for alarm," I said over my shoulder; "Mr.
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 massaged, was occasioning him great pain. But
the danger was past, and already that glassy look was disappearing
from his eyes, nor did they protrude so unnaturally.

"God, Petrie!" he whispered, "that was a near shave! I haven't the
strength of a kitten!"

"The weakness will pass 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 casements, 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 f
