"The key is half-turned," he said. "I can't see nothing except just the light."
"Here's Mr. McIntyre," cried half-a-dozen voices, as Robert came forward.
"We'll have to beat the door in, sir," said the policeman. "We can't get any sort of answer, and there's something wrong."
Twice and thrice they threw their united weights against it until at last with a sharp snap the lock broke, and they crowded into the narrow passage. The inner door was ajar, and the laboratory lay before them.
In the centre was an enormous heap of fluffy grey ash, reaching up half-way to the ceiling. Beside it was another heap, much smaller, of some brilliant scintillating dust, which shimmered brightly in the rays of the electric light. All round was a bewildering chaos of broken jars, shattered bottles, cracked machinery, and tangled wires, all bent and draggled. And there in the midst of this universal ruin, leaning back in his chair with his hands clasped upon his lap, and the easy pose of one who rests after hard work safely carried through, sat Raffles Haw, the master of the house, and the richest of mankind, with the pallor of death upon his face. So easily he sat and so naturally, with such a serene expression upon his features, that it was not until they raised him, and touched his cold and rigid limbs, that they could realise that he had indeed passed away.
Reverently and slowly they bore him to his room, for he was beloved by all who had served him. Robert alone lingered with the policeman in the laboratory. Like a man in a dream he wandered about, marvelling at the universal destruction. A large broad-headed hammer lay upon the ground, and with this Haw had apparently set himself to destroy all his apparatus, having first used his electrical machines to reduce to protyle all the stock of gold which he had accumulated. The treasure-room which had so dazzled Robert consisted now of merely four bare walls, while the gleaming dust upon the floor proclaimed the fate of that magnificent collection of gems which had alone amounted to a royal fortune. Of all the machinery no single piece remained intact, and even the glass table was shattered into three pieces. Strenuously earnest must have been the work which Raffles Haw had done that day.
And suddenly Robert thought of the secret which had been treasured in the casket within the iron-clamped box. It was to tell him the one last essential link which would make his knowledge of the process complete. Was it still there? Thrilling all over, he opened the great chest, and drew out the ivory box. It was locked, but the key was in it. He turned it and threw open the lid. There was a white slip of paper with his own name written upon it. With trembling fingers he unfolded it. Was he the heir to the riches of El Dorado, or was he destined to be a poor struggling artist? The note was dated that very evening, and ran in this way:
"MY DEAR ROBERT,--My secret shall never be used again. I cannot tell you how I thank Heaven that I did not entirely confide it to you, for I should have been handing over an inheritance of misery both to yourself and others. For myself I have hardly had a happy moment since I discovered it. This I could have borne had I been able to feel that I was doing good, but, alas! the only effect of my attempts has been to turn workers into idlers, contented men into greedy parasites, and, worst of all, true, pure women into deceivers and hypocrites. If this is the effect of my interference on a small scale, I cannot hope for anything better were I to carry out the plans which we have so often discussed. The schemes of my life have all turned to nothing. For myself, you shall never see me again. I shall go back to the student life from which I emerged. There, at least, if I can do little good, I can do no harm. It is my wish that such valuables as remain in the Hall should be sold, and the proceeds divided amidst all the charities of Birmingham. I shall leave tonight if I am well enough, but I have been much troubled all day by a stabbing pain in my side.
