"I'll see that he's looked after," said I, grimly, and went and bolted the front door, lest he should return before I had decided on my tactics.

In the few seconds that my back was turned, Sarah seemed to have acquired yet another new and novel point of view. I found the old heroine almost gloating over her master's dreadful handiwork.

"Well, there, I never did see anything so artful! Him at his theatre, to come home and look on at the fire, and me at my concert, safe and sound as if I was at church! Oh, he'd see to that, sir; he wouldn't've done it if he 'adn't've arranged to put me out of 'arm's way. That's Mr. Nettleton, every inch. Not that I say it was a right thing to do, sir, even with the 'ouse empty as it is. But what can you expect when a pore gentleman goes out of 'is 'ead? There's not many would care what 'appened to nobody else! But the artfulness of 'im: in another minute the whole 'ouse might've been blazing like a bonfire! Well, there, you do 'ear of such things, and now we know 'ow they 'appen."

To this extraordinary tune, with many such variations, I was meanwhile making up my mind. The first necessity was to place the intrepid old fool really out of harm's way, and the next was to save the house if possible, but also and at all costs the good name of the Witching Hill Estate. We had had one suicide, and it had not been hushed up quite as successfully as some of us flattered ourselves at the time; one case of gross intemperance, most scandalous while it lasted, and one gang of burglars actually established on the Estate. People were beginning to talk about us as it was; a case of attempted arson, even if the incendiary were proved a criminal lunatic, might be the end of us as a flourishing concern. It is true that I had no stake in the Company whose servant I was; but one does not follow the dullest avocation for three years without taking a certain interest of another kind. At any rate I intended the secret of this locked room to remain as much a secret as I could keep it, and this gave me an immediate leverage over Sarah. Unless she took herself off before her master returned, I assured her I would have him sent, not to an asylum, but to the felon's cell which I described as the proper place for him. I was not so sure in my own mind that I meant him to go to one or the other. But this was the bargain that I proposed to Sarah.

It came out that she had friends, in the shape of a labouring brother and his wife and family, whom I strongly suspected of having migrated on purpose to keep in touch with Sarah's kitchen, no further away than the Village. I succeeded in packing the old thing off in that direction, after making her lock her door at the top of the house. Previously I had removed the marks of my boot from the extinguished candles, and had left the locked room locked once more and in total darkness. Sarah and I quitted the house together before ten o'clock.

"I'll see that your master doesn't do himself any damage to-night," were my last words to her. "He'll think the candles have been blown out by a draught under the door—which really wouldn't catch them till they burnt quite low—and that you are asleep in your bed at the top of the house. You've left everything as though you were; and that alone, as you yourself have pointed out, is enough to guarantee his not trying it on again to-night. You see, the fire was timed to break out before you left your entertainment, as it would have done if you'd seen the programme through. Tell your people that Mr. Nettleton's away for the night, and you've gone and locked yourself out by mistake. Above all, don't come back, unless you want to give the whole show away; he'd know at once that you'd discovered everything, and even your life wouldn't be safe for another minute. Unless you promise, Sarah, I'll just wait for him myself—with a policeman!"

My reasoning was cogent enough for that simple mind; on the other hand, the word of such an obviously faithful soul was better than the bond of most; and altogether it was with considerable satisfaction that I heard old Sarah trot off into the night, and then myself ran every yard of the way back to the Delavoyes' house.

Up to this point, as I still think, I had done better than many might have done in my place. But for my promise to Uvo, and the fact that he was even then lying waiting for me to redeem it, I would not have rushed to a sick man with my tale. Yet I must say that I was thankful I had no other choice, as matters stood. And I will even own that I had formed no definite plans beyond the point at which Uvo, having heard all, was to give me the benefit of his sound judgment in any definite dilemma.

To my sorrow he took the whole thing in an absolutely different way from any that I had anticipated. He took it terribly to heart. I had entirely forgotten the gist of our conversation before I left him; he had been thinking of nothing else. The thing that I had expected to thrill him to the marrow, that would have done nothing else at any other time, simply harrowed him after what it seemed that I had said three-quarters of an hour before. Whatever I had said was overlaid in my mind, for the moment, by all that I had since seen and heard. But Uvo Delavoye might have been brooding over every syllable.

"You said you wouldn't envy me," he cried, huskily, "if poor old Nettleton fell under the influence in his turn. You spoke as if it was my influence; it isn't, but it may be that I'm a sort of medium for its transmission! Sole agent, eh, Gilly? My God, that's an awful thought, but you gave it me just now and I sha'n't get shot of it in a hurry! None of these beastly things happened before I came here—I, the legitimate son of this infernal soil! I'm the lightning-conductor, I'm the middleman in every deal!"
