MacIan lifted his head and looked at the Master steadily, but Turnbull did not look up.

“This, we found, was the only way with all superstitions,” continued the speaker; “it was necessary to deny them historically, and we have done it with great success in the case of miracles and such things. Now within our own time there arose an unfortunate fuss which threatened (as Mr. Turnbull would say) to galvanize the corpse of Christianity into a fictitious life–the alleged case of a Highland eccentric who wanted to fight for the Virgin.”

MacIan, quite white, made a step forward, but the speaker did not alter his easy attitude or his flow of words. “Again we urged that this duel was not to be admired, that it was a mere brawl, but the people were ignorant and romantic. There were signs of treating this alleged Highlander and his alleged opponent as heroes. We tried all other means of arresting this reactionary hero worship. Working men who betted on the duel were imprisoned for gambling. Working men who drank the health of a duellist were imprisoned for drunkenness. But the popular excitement about the alleged duel continued, and we had to fall back on our old historical method. We investigated, on scientific principles, the story of MacIan’s challenge, and we are happy to be able to inform you that the whole story of the attempted duel is a fable. There never was any challenge. There never was any man named MacIan. It is a melodramatic myth, like Calvary.”

Not a soul moved save Turnbull, who lifted his head; yet there was the sense of a silent explosion.

“The whole story of the MacIan challenge,” went on the Master, beaming at them all with a sinister benignity, “has been found to originate in the obsessions of a few pathological types, who are now all fortunately in our care. There is, for instance, a person here of the name of Gordon, formerly the keeper of a curiosity shop. He is a victim of the disease called Vinculomania– the impression that one has been bound or tied up. We have also a case of Fugacity (Mr. Whimpey), who imagines that he was chased by two men.”

The indignant faces of the Jew shopkeeper and the Magdalen Don started out of the crowd in their indignation, but the speaker continued:

“One poor woman we have with us,” he said, in a compassionate voice, “believes she was in a motor-car with two such men; this is the well-known illusion of speed on which I need not dwell. Another wretched woman has the simple egotistic mania that she has caused the duel. Madeleine Durand actually professes to have been the subject of the fight between MacIan and his enemy, a fight which, if it occurred at all, certainly began long before. But it never occurred at all. We have taken in hand every person who professed to have seen such a thing, and proved them all to be unbalanced. That is why they are here.”

The Master looked round the room, just showing his perfect teeth with the perfection of artistic cruelty, exalted for a moment in the enormous simplicity of his success, and then walked across the hall and vanished through an inner door. His two lieutenants, Quayle and Hutton, were left standing at the head of the great army of servants and keepers.

“I hope we shall have no more trouble,” said Dr. Quayle pleasantly enough, and addressing Turnbull, who was leaning heavily upon the back of a chair.

Still looking down, Turnbull lifted the chair an inch or two from the ground. Then he suddenly swung it above his head and sent it at the inquiring doctor with an awful crash which sent one of its wooden legs loose along the floor and crammed the doctor gasping into a corner. MacIan gave a great shout, snatched up the loose chair-leg, and, rushing on the other doctor, felled him with a blow. Twenty attendants rushed to capture the rebels; MacIan flung back three of them and Turnbull went over on top of one, when from behind them all came a shriek as of something quite fresh and frightful.

Two of the three passages leading out of the hall were choked with blue smoke. Another instant and the hall was full of the fog of it, and red sparks began to swarm like scarlet bees.

“The place is on fire!” cried Quayle with a scream of indecent terror. “Oh, who can have done it? How can it have happened?”

A light had come into Turnbull’s eyes. “How did the French Revolution happen?” he asked.

“Oh, how should I know!” wailed the other.

“Then I will tell you,” said Turnbull; “it happened because some people fancied that a French grocer was as respectable as he looked.”

Even as he spoke, as if by confirmation, old Mr. Durand re-entered the smoky room quite placidly, wiping the petroleum from his hands with a handkerchief. He had set fire to the building in accordance with the strict principles of the social contract.

But MacIan had taken a stride forward and stood there shaken and terrible. “Now,” he cried, panting, “now is the judgement of the world. The doctors will leave this place; the keepers will leave this place. They will leave us in charge of the machinery and the machine-guns at the windows. But we, the lunatics, will wait to be burned alive if only we may see them go.”

“How do you know we shall go?” asked Hutton, fiercely.

“You believe nothing,” said MacIan, simply, “and you are insupportably afraid of death.”

“So this is suicide,” sneered the doctor; “a somewhat doubtful sign of sanity.”

“Not at all–this is vengeance,” answered Turnbull, quite calmly; “a thing which is completely healthy.”

“You think the doctors will go,” said Hutton, savagely.

“The keepers have gone already,” said Turnbull.

Even as they spoke the main doors were burst open in mere brutal panic, and all the officers and subordinates of the asylum rushed away across the garden pursued by the smoke. But among the ticketed maniacs not a man or woman moved.

“We hate dying,” said Turnbull, with composure, “but we hate you even more. This is a successful revolution.”

In the roof above their heads a panel shot back, showing a strip of star-lit sky and a huge thing made of white metal, with the shape and fins of a fish, swinging as if at anchor. At the same moment a steel ladder slid down from the opening and struck the floor, and the cleft chin of the mysterious Master was thrust into the opening. “Quayle, Hutton,” he said, “you will escape with me.” And they went up the ladder like automata of lead.

Long after they had clambered into the car, the creature with the cloven face continued to leer down upon the smoke-stung crowd below. Then at last he said in a silken voice and with a smile of final satisfaction:

“By the way, I fear I am very absent minded. There is one man specially whom, somehow, I always forget. I always leave him lying about. Once I mislaid him on the Cross of St. Paul’s. So silly of me; and now I’ve forgotten him in one of those little cells where your fire is burning. Very unfortunate–especially for him.” And nodding genially, he climbed into his flying ship.

MacIan stood motionless for two minutes, and then rushed down one of the suffocating corridors till he found the flames. Turnbull looked once at Madeleine, and followed.

MacIan, with singed hair, smoking garments, and smarting hands and face, had already broken far enough through the first barriers of burning timber to come within cry of the cells he had once known. It was impossible, however, to see the spot where the old man lay dead or alive; not now through darkness, but through scorching and aching light. The site of the old half-wit’s cell was now the heart of a standing forest of fire–the flames as thick and yellow as a cornfield. Their incessant shrieking and crackling was like a mob shouting against an orator. Yet through all that deafening density MacIan thought he heard a small and separate sound. When he heard it he rushed forward as if to plunge into that furnace, but Turnbull arrested him by an elbow.
