“I don’t think we need go into all that,” he said at last, after his visitor had gone into a good deal of it, and seemed alarmingly capable of going into a good deal more. “If you’re sure it’s a case of that sort, a case of really dangerous mania, I suppose it’s all right.”

“In all my experience,” said Dr. Hendry solemnly, and with a full sense of responsibility, “I have never known a clearer one. This optical question is becoming grave, sir. It is becoming menacing. Even at this moment, while I speak, persons unquestionably mad are wandering about the world, and even delivering authoritative opinions on scientific subjects. Only the other day–.”

At this moment his melodious and persuasive voice was drowned for an instant in very remarkable sounds from the next room. The noise resembled that of some huge and heavy body being hurled against the door; and in the silence that followed something like guttural imprecations, as if hoarse and faint with fury, could be heard through the thick partition.

“Good heavens!” cried Mr. Wotton, awakening with a start and looking up for the first time. “What on earth was that?”

Dr. Hendry wagged his head with a beautiful sadness, but he continued to smile.

“Ours is a melancholy occupation,” he said. “Dealing with the weaker and the wilder aspects of our fallen nature . . . the body of our humiliation, I think it is in the Greek Testament . . . the body of our humiliation. It sounds only too like the struggle of some unfortunate whom society finds it a sad necessity to restrain.”

At this moment the body of our humiliation was again thrown crashing against the door; and it seemed to be a body of some weight and momentum and even nobility. The magistrate was not altogether satisfied. Patients or prisoners (or whatever the new social victims ought to be called) were indeed frequently taken into the adjoining room to await examination; but generally under the guardianship of attendants who would prevent them indicating their impatience in so lively a style. The only other hypothesis was that the lunatic next door was so exceedingly lively as to have killed his keeper.

Whatever else the old army surgeon was, he was a man of courage. He got up from his desk and went across to the door that was still shaking and vibrating with the shocks from within. He looked at it for a moment with his head on one side; and then deliberately unlocked it. Though he showed no fear, he had to show a good deal of agility, in leaping back and not being flung flat on the floor by the thing that came out of the room. At that moment he would have called it a thing rather than a man. It had goggle eyes that stood out of its head like horns; and Mr. Wotton had a confused feeling confirming the doctor’s theory that the unfortunate creature must have something the matter with its eyes. It had long tawny tufts of moustache and hair standing out in all directions; for it had been ineffectually brushing its hair against the wall for some time past. It was only when it had fallen into the full daylight of the room that the magistrate saw that it was wearing a white waistcoat and a grey pair of trousers, such as are seldom worn by a walrus or even a wild man of the woods.

“Well, anyhow,” he muttered, “he is clothed, if not exactly in his right mind.”

The huge man who had fallen through the doorway straightened himself and stood up with a rather wild stare; his tawny tusks more aggressive than ever. But it soon became apparent at least that he possessed the power of speech. His first remarks, being curses in a Continental language, might indeed have been mistaken for inarticulate cries; but the two scientific characters who were listening to him were soon able to recognise the sound of scientific language disentangling itself from other foreign languages. In fact, the official doctor was making his official report; but it did not sound like that.
