“’E’s a damned ass,” said the man.

“He is,” said Dr. O’Grady. “Still, even an ass, if he goes on experimenting for four months in a chamber specially set apart for research, is sure to hit upon something that will explode by the end of the time. By the way, do you happen to know where he got that dining-room wall-paper with the crocodiles on it?”

The door opened and Mr. Red stalked into the room.

“Follow me,” he said to Dr. O’Grady.

“All right. I’ve finished with this fellow’s legs for the present. I’ll call again to-morrow afternoon, or rather, this afternoon. He’ll get along all right. There’s nothing to be frightened about. You may give him a little beef-tea and—— Damn it all! Augustus Cæsar has gone! Good-bye, my man. I’ll see you again soon. I must hurry off now. It won’t do to keep the Field Marshal waiting. The crocodiles might get on his nerves if he was left too long in the room alone with them.”


CHAPTER III

Dr. O’Grady left the room and closed the door behind him. His spirits, owing to the ten-pound note which lay in his breast pocket, were cheerful. He whistled “The Minstrel Boy” as he walked along the passage. Just as he reached that part of the tune which goes with the discovery of the boy in the ranks of death he stopped abruptly and swore. He was seized from behind by two men, flung to the ground with some violence, and held there flat on his back. A few useless struggles convinced him that he could not make good his escape. He lay still and looked at his captors. The foreign gentleman with the long black beard was one of them. The other was the man whom Dr. O’Grady had declared to be a Norwegian. He was a powerful man, adorned with a mass of fair hair which fell down over his forehead and gave him a look of unkempt ferocity. Behind these two who knelt beside and on Dr. O’Grady stood Mr. Red.

“Hullo, Emperor!” said the Doctor, “what’s the game now? If you want a gladiatorial show, with me and these two swashbucklers as chief performers, you ought to have given me fair notice. You can’t expect a man to put up much of a fight when he’s caught from behind just as he’s in the middle of whistling a tune.”
