“It occurred to me that the radiators, if they fell into the hands of some acute well-educated person, would give me away too much, and watching my opportunity, I came into the room and tilted one of the little dynamos off its fellow on which it was standing, and smashed both apparatus. Then, while they were trying to explain the smash, I dodged out of the room and went softly downstairs.

“I went into one of the sitting-rooms and waited until they came down, still speculating and argumentative, all a little disappointed at finding no ‘horrors,’ and all a little puzzled how they stood legally towards me. Then I slipped up again with a box of matches, fired my heap of paper and rubbish, put the chairs and bedding thereby, led the gas to the affair, by means of an india-rubber tube, and waving a farewell to the room left it for the last time.”

“You fired the house!” exclaimed Kemp.

“Fired the house. It was the only way to cover my trail — and no doubt it was insured. I slipped the bolts of the front door quietly and went out into the street. I was invisible, and I was only just beginning to realise the extraordinary advantage my invisibility gave me. My head was already teeming with plans of all the wild and wonderful things I had now impunity to do.

“In going downstairs the first time I found an unexpected difficulty because I could not see my feet; indeed I stumbled twice, and there was an unaccustomed clumsiness in gripping the bolt. By not looking down, however, I managed to walk on the level passably well.

“My mood, I say, was one of exaltation. I felt as a seeing man might do, with padded feet and noiseless clothes, in a city of the blind. I experienced a wild impulse to jest, to startle people, to clap men on the back, fling people’s hats astray, and generally revel in my extraordinary advantage.

“But hardly had I emerged upon Great Portland Street, however (my lodging was close to the big draper’s shop there), when I heard a clashing concussion and was hit violently behind, and turning saw a man carrying a basket of soda-water syphons, and looking in amazement at his burden. Although the blow had really hurt me, I found something so irresistible in his astonishment that I laughed aloud. ‘The devil’s in the basket,’ I said, and suddenly twisted it out of his hand. He let go incontinently, and I swung the whole weight into the air.

“But a fool of a cabman, standing outside a public house, made a sudden rush for this, and his extending fingers took me with excruciating violence under the ear. I let the whole down with a smash on the cabman, and then, with shouts and the clatter of feet about me, people coming out of shops, vehicles pulling up, I realised what I had done for myself, and cursing my folly, backed against a shop window and prepared to dodge out of the confusion. In a moment I should be wedged into a crowd and inevitably discovered. I pushed by a butcher boy, who luckily did not turn to see the nothingness that shoved him aside, and dodged behind the cab-man’s four-wheeler. I do not know how they settled the business, I hurried straight across the road, which was happily clear, and hardly heeding which way I went, in the fright of detection the incident had given me, plunged into the afternoon throng of Oxford Street.
