“Three or four hours—the cat. The bones and sinews and the fat were the last to go, and the tips of the coloured hairs. And, as I say, the back part of the eye, tough, iridescent stuff it is, wouldn’t go at all.

“It was night outside long before the business was over, and nothing was to be seen but the dim eyes and the claws. I stopped the gas engine, felt for and stroked the beast, which was still insensible, and then, being tired, left it sleeping on the invisible pillow and went to bed. I found it hard to sleep. I lay awake thinking weak aimless stuff, going over the experiment over and over again, or dreaming feverishly of things growing misty and vanishing about me, until everything, the ground I stood on, vanished, and so I came to that sickly falling nightmare one gets. About two, the cat began miaowing about the room. I tried to hush it by talking to it, and then I decided to turn it out. I remember the shock I had when striking a light—there were just the round eyes shining green—and nothing round them. I would have given it milk, but I hadn’t any. It wouldn’t be quiet, it just sat down and miaowed at the door. I tried to catch it, with an idea of putting it out of the window, but it wouldn’t be caught, it vanished. Then it began miaowing in different parts of the room. At last I opened the window and made a bustle. I suppose it went out at last. I never saw any more of it.

“Then—Heaven knows why—I fell thinking of my father’s funeral again, and the dismal windy hillside, until the day had come. I found sleeping was hopeless, and, locking my door after me, wandered out into the morning streets.”

“You don’t mean to say there’s an invisible cat at large!” said Kemp.

“If it hasn’t been killed,” said the Invisible Man. “Why not?”

“Why not?” said Kemp. “I didn’t mean to interrupt.”

“It’s very probably been killed,” said the Invisible Man. “It was alive four days after, I know, and down a grating in Great Titchfield Street; because I saw a crowd round the place, trying to see whence the miaowing came.”

He was silent for the best part of a minute. Then he resumed abruptly:

“I remember that morning before the change very vividly. I must have gone up Great Portland Street. I remember the barracks in Albany Street, and the horse soldiers coming out, and at last I found the summit of Primrose Hill. It was a sunny day in January—one of those sunny, frosty days that came before the snow this year. My weary brain tried to formulate the position, to plot out a plan of action.

“I was surprised to find, now that my prize was within my grasp, how inconclusive its attainment seemed. As a matter of fact I was worked out; the intense stress of nearly four years’ continuous work left me incapable of any strength of feeling. I was apathetic, and I tried in vain to recover the enthusiasm of my first inquiries, the passion of discovery that had enabled me to compass even the downfall of my father’s grey hairs. Nothing seemed to matter. I saw pretty clearly this was a transient mood, due to overwork and want of sleep, and that either by drugs or rest it would be possible to recover my energies.
