“‘After you went to bed?’

“‘Yes.’

“‘When did you go to bed?’

“‘About eleven.’

“‘So your son was gone at least two hours?’

“‘Yes.’

“‘Possibly four or five?’

“‘Yes.’

“‘What was he doing during that time?’

“‘I do not know,’ she answered, turning white to her very lips.

“Of course after that there was nothing more to be done. I found out where Lieutenant Charpentier was, took two officers with me, and arrested him. When I touched him on the shoulder and warned him to come quietly with us, he answered us as bold as brass, ‘I suppose you are arresting me for being concerned in the death of that scoundrel Drebber,’ he said. We had said nothing to him about it, so that his alluding to it had a most suspicious aspect.”

“Very,” said Holmes.

“He still carried the heavy stick which the mother described him as having with him when he followed Drebber. It was a stout oak cudgel.”

“What is your theory, then?”

“Well, my theory is that he followed Drebber as far as the Brixton Road. When there, a fresh altercation arose between them, in the course of which Drebber received a blow from the stick, in the pit of the stomach perhaps, which killed him without leaving any mark. The night was so wet that no one was about, so Charpentier dragged the body of his victim into the empty house. As to to the candle, and the blood, and the writing on the wall, and the ring, they may all be so many tricks to throw the police on to the wrong scent.”

“Well done!” said Holmes in an encouraging voice. “Really, Gregson, you are getting along. We shall make something of you yet.”

“I flatter myself that I have managed it rather neatly,” the detective answered, proudly. “The young man volunteered a statement, in which he said that after following Drebber some time, the latter perceived him, and took a cab in order to get away from him. On his way home he met an old shipmate, and took a long walk with him. On being asked where this old shipmate lived, he was unable to give any satisfactory reply. I think the whole case fits together uncommonly well. What amuses me is to think of Lestrade, who had started off upon the wrong scent. I am afraid he won’t make much of it. Why, by Jove, here’s the very man himself!”

It was indeed Lestrade, who had ascended the stairs while we were talking, and who now entered the room. The assurance and jauntiness which generally marked his demeanour and dress were, however, wanting. His face was disturbed and troubled, while his clothes were disarranged and untidy. He had evidently come with the intention of consulting with Sherlock Holmes, for on perceiving his colleague he appeared to be embarrassed and put out. He stood in the centre of the room, fumbling nervously with his hat and uncertain what to do. “This is a most extraordinary case,” he said at last — “a most incomprehensible affair.”

Everything in the world has its function, and is good or not good in so far as it fulfils this function more or less perfectly. Was a miner a good miner? Then he was complete. Was a manager a good manager? That was enough. Gerald himself, who was responsible for all this industry, was he a good director? If he were, he had fulfilled his life. The rest was by–play.

The mines were there, they were old. They were giving out, it did not pay to work the seams. There was talk of closing down two of them. It was at this point that Gerald arrived on the scene.

He looked around. There lay the mines. They were old, obsolete. They were like old lions, no more good. He looked again. Pah! the mines were nothing but the clumsy efforts of impure minds. There they lay, abortions of a half–trained mind. Let the idea of them be swept away. He cleared his brain of them, and thought only of the coal in the under earth. How much was there?

There was plenty of coal. The old workings could not get at it, that was all. Then break the neck of the old workings. The coal lay there in its seams, even though the seams were thin. There it lay, inert matter, as it had always lain, since the beginning of time, subject to the will of man. The will of man was the determining factor. Man was the archgod of earth. His mind was obedient to serve his will. Man’s will was the absolute, the only absolute.

And it was his will to subjugate Matter to his own ends. The subjugation itself was the point, the fight was the be–all, the fruits of victory were mere results. It was not for the sake of money that Gerald took over the mines. He did not care about money, fundamentally. He was neither ostentatious nor luxurious, neither did he care about social position, not finally. What he wanted was the pure fulfilment of his own will in the struggle with the natural conditions. His will was now, to take the coal out of the earth, profitably. The profit was merely the condition of victory, but the victory itself lay in the feat achieved. He vibrated with zest before the challenge. Every day he was in the mines, examining, testing, he consulted experts, he gradually gathered the whole situation into his mind, as a general grasps the plan of his campaign.

Then there was need for a complete break. The mines were run on an old system, an obsolete idea. The initial idea had been, to obtain as much money from the earth as would make the owners comfortably rich, would allow the workmen sufficient wages and good conditions, and would increase the wealth of the country altogether. Gerald’s father, following in the second generation, having a sufficient fortune, had thought only of the men. The mines, for him, were primarily great fields to produce bread and plenty for all the hundreds of human beings gathered about them. He had lived and striven with his fellow owners to benefit the men every time. And the men had been benefited in their fashion. There were few poor, and few needy. All was plenty, because the mines were good and easy to work. And the miners, in those days, finding themselves richer than they might have expected, felt glad and triumphant. They thought themselves well–off, they congratulated themselves on their good–fortune, they remembered how their fathers had starved and suffered, and they felt that better times had come. They were grateful to those others, the pioneers, the new owners, who had opened out the pits, and let forth this stream of plenty.
