Simpkins looked at the light and blinked his eyes. That had a violet shade. He really did not care for science, and he had an inclination to put the book down as his head seemed to be swaying, but he continued to turn the pages.

Snowdon is the highest mountain in England or Wales. Snowdon is not so high as Ben Nevis.

Therefore the highest mountain in England or Wales is not so high as Ben Nevis.

“Oh, my head!” mumbled Simpkins.

Water must be either warm or not warm, but it does not follow that it must be warm or cold.

Simpkins felt giddy. He dropped the book, and tottered to the couch. Immediately the room spun round and something in his head began to hum, to roar like an aeroplane a long way up in the sky. He felt that he ought to get out of the room, quickly, and get some water, either not or cold warm—he didn’t mind which! He clapped on his hat and, slipping into his overcoat, he reached a door. It opened into a bedroom, very bare indeed compared with this other room, but Simpkins rolled in; the door slammed behind him, and in the darkness he fell upon a bed, with queer sensations that seemed to be dividing and subtracting in him.

When he awoke later—oh, it seemed much later—he felt quite well again. He had forgotten where he was. It was a strange place he was in, utterly dark; but there was a great noise sounding quite close to him—a gramophone, people shouting choruses and dancing about in the adjoining room. He could hear a lady’s voice too. Then he remembered that he ought not to be in that room at all; it was, why, yes, it was criminal; he might be taken for a burglar or something! He slid from the bed, groped in the darkness until he found his hat, unbuttoned his coat, for he was fearfully hot, and stood at the bedroom door trembling in the darkness, waiting and listening to that tremendous row. He had been a fool to come in there! How was he to get out—how the deuce was he to get out? The gramophone stopped. He could hear the voices more plainly. He grew silently panic-stricken; it was awful, they’d be coming in to him perhaps, and find him sneaking there like a thief—he must get out, he must, he must get out; yes, but how?

The singing began again. The men kept calling out “Lulu! Lulu!” and a lady’s gay voice would reply to a Charley or a George, and so on, when all at once there came a peremptory knock at the outer door. The noise within stopped immediately. Deep silence. Simpkins could hear whispering. The people in there were startled; he could almost feel them staring at each other with uneasiness. The lady laughed out startlingly shrill. “Sh-s-s-sh!” the others cried. The loud knocking began again, emphatic, terrible. Simpkins’ already quaking heart began to beat ecstatically. Why, oh why, didn’t they open that door?—open it! open it! There was shuffling in the room, and when the knocking was repeated for the third time the outer door was apparently unlocked.

“Fazz! Oh, Fazz, you brute!” cried the relieved voices in the room. “You fool, Fazz! Come in, damn you, and shut the door.”

“Good gracious!” exclaimed the apparently deliberating Fazz, “what is that?”

“Hullo, Rob Roy!” cried the lady, “it’s me.”
