Exhausted and wounded as the Invisible Man was, he refused to accept Kemp's word that his freedom should be respected. He examined the two windows of the bedroom, drew up the blinds and opened the sashes, to confirm Kemp's statement that a retreat by them would be possible. Outside the night was very quiet and still, and the new moon was setting over the down. Then he examined the keys of the bedroom and the two dressing-room doors, to satisfy himself that these also could be made an assurance of freedom. Finally he expressed himself satisfied. He stood on the hearth rug and Kemp heard the sound of a yawn.

"I'm sorry," said the Invisible Man, "if I cannot tell you all that I have done to-night. But I am worn out. It's grotesque, no doubt. It's horrible! But believe me, Kemp, in spite of your arguments of this morning, it is quite a possible thing. I have made a discovery. I meant to keep it to myself. I can't. I must have a partner. And you.... We can do such things ... But to-morrow. Now, Kemp, I feel as though I must sleep or perish."

Kemp stood in the middle of the room staring at the headless garment. "I suppose I must leave you," he said. "It's--incredible. Three things happening like this, overturning all my preconceptions--would make me insane. But it's real! Is there anything more that I can get you?"

"Only bid me good-night," said Griffin.

"Good-night," said Kemp, and shook an invisible hand. He walked sideways to the door. Suddenly the dressing-gown walked quickly towards him. "Understand me!" said the dressing-gown. "No attempts to hamper me, or capture me! Or--"

Kemp's face changed a little. "I thought I gave you my word," he said.

Kemp closed the door softly behind him, and the key was turned upon him forthwith. Then, as he stood with an expression of passive amazement on his face, the rapid feet came to the door of the dressing-room and that too was locked. Kemp slapped his brow with his hand. "Am I dreaming? Has the world gone mad--or have I?"

He laughed, and put his hand to the locked door. "Barred out of my own bedroom, by a flagrant absurdity!" he said.

He walked to the head of the staircase, turned, and stared at the locked doors. "It's fact," he said. He put his fingers to his slightly bruised neck. "Undeniable fact!

"But--"

He shook his head hopelessly, turned, and went downstairs.

He lit the dining-room lamp, got out a cigar, and began pacing the room, ejaculating. Now and then he would argue with himself.

"Invisible!" he said.

"Is there such a thing as an invisible animal? ... In the sea, yes. Thousands--millions. All the larvae, all the little nauplii and tornarias, all the microscopic things, the jelly-fish. In the sea there are more things invisible than visible! I never thought of that before. And in the ponds too! All those little pond-life things--specks of colourless translucent jelly! But in air? No!

"It can't be.

"But after all--why not?

"If a man was made of glass he would still be visible."

His meditation became profound. The bulk of three cigars had passed into the invisible or diffused as a white ash over the carpet before he spoke again. Then it was merely an exclamation. He turned aside, walked out of the room, and went into his little consulting-room and lit the gas there. It was a little room, because Dr. Kemp did not live by practice, and in it were the day's newspapers. The morning's paper lay carelessly opened and thrown aside. He caught it up, turned it over, and read the account of a "Strange Story from Iping" that the mariner a............
