“Father, may I have that chart? I should like to study it during the day!”

“Certainly, my dear!” answered Mr. Trelawny heartily, as he handed it to her. He resumed his instructions in a different tone, a more matter-of-fact one suitable to a practical theme which had no mystery about it:

“I think you had better all understand the working of the electric light in case any sudden contingency should arise. I dare say you have noticed that we have a complete supply in every part of the house, so that there need not be a dark corner anywhere. This I had specially arranged. It is worked by a set of turbines moved by the flowing and ebbing tide, after the manner of the turbines at Niagara. I hope by this means to nullify accident and to have without fail a full supply ready at any time. Come with me and I will explain the system of circuits, and point out to you the taps and the fuses.” I could not but notice, as we went with him all over the house, how absolutely complete the system was, and how he had guarded himself against any disaster that human thought could foresee.

But out of the very completeness came a fear! In such an enterprise as ours the bounds of human thought were but narrow. Beyond it lay the vast of Divine wisdom, and Divine power!

When we came back to the cave, Mr. Trelawny took up another theme:

“We have now to settle definitely the exact hour at which the Great Experiment is to be made. So far as science and mechanism go, if the preparations are complete, all hours are the same. But as we have to deal with preparations made by a woman of extraordinarily subtle mind, and who had full belief in magic and had a cryptic meaning in everything, we should place ourselves in her position before deciding. It is now manifest that the sunset has an important place in the arrangements. As those suns, cut so mathematically by the edge of the sarcophagus, were arranged of full design, we must take our cue from this. Again, we find all along that the number seven has had an important bearing on every phase of the Queen’s thought and reasoning and action. The logical result is that the seventh hour after sunset was the time fixed on. This is borne out by the fact that on each of the occasions when action was taken in my house, this was the time chosen. As the sun sets tonight in Cornwall at eight, our hour is to be three in the morning!” He spoke in a matter-of-fact way, though with great gravity; but there was nothing of mystery in his word or manner. Still, we were all impressed to a remarkable degree. I could see this in the other men by the pallor that came on some of their faces, and by the stillness and unquestioning silence with which the decision was received. The only one who remained in any way at ease was Margaret, who had lapsed into one of her moods of abstraction, but who seemed to wake up to a note of gladness. Her father, who was watching her intently, smiled; her mood was to him a direct confirmation of his theory.

For myself I was almost overcome. The definite fixing of the hour seemed like the voice of Doom. When I think of it now, I can realise how a condemned man feels at his sentence, or at the sounding of the last hour he is to hear.

There could be no going back now! We were in the hands of God!

The hands of God...! And yet...! What other forces were arrayed? ... What would become of us all, poor atoms of earthly dust whirled in the wind which cometh whence and goeth whither no man may know. It was not for myself.... Margaret...!

I was recalled by Mr. Trelawny’s firm voice:
