“I must go and see Caswall to-morrow, to hear what he has to say on the subject.”

“But, dear, for my sake, don’t have any quarrel with Mr. Caswall.  I have had too much trial and pain lately to wish it increased by any anxiety regarding you.”

“You shall not, dear—­if I can help it—­please God,” he said solemnly, and he kissed her.

Then, in order to keep her interested so that she might forget the fears and anxieties that had disturbed her, he began to talk over the details of her adventure, making shrewd comments which attracted and held her attention.  Presently, inter alia, he said: 

“That’s a dangerous game Caswall is up to.  It seems to me that that young man—­though he doesn’t appear to know it—­is riding for a fall!”

“How, dear?  I don’t understand.”

“Kite flying on a night like this from a place like the tower of Castra Regis is, to say the least of it, dangerous.  It is not merely courting death or other accident from lightning, but it is bringing the lightning into where he lives.  Every cloud that is blowing up here—­and they all make for the highest point—­is bound to develop into a flash of lightning.  That kite is up in the air and is bound to attract the lightning.  Its cord makes a road for it on which to travel to earth.  When it does come, it will strike the top of the tower with a weight a hundred times greater than a whole park of artillery, and will knock Castra Regis into pieces.  Where it will go after that, no one can tell.  If there should be any metal by which it can travel, such will not only point the road, but be the road itself.”

“Would it be dangerous to be out in the open air when such a thing is taking place?” she asked.

“No, little woman.  It would be the safest possible place—­so long as one was not in the line of the electric current.”

“Then, do let us go outside.  I don’t want to run into any foolish danger—­or, far more, to ask you to do so.  But surely if the open is safest, that is the place for us.”

Without another word, she put on again the cloak she had thrown off, and a small, tight-fitting cap.  Adam too put on his cap, and, after seeing that his revolver was all right, gave her his hand, and they left the house together.

“I think the best thing we can do will be to go round all the places which are mixed up in this affair.”

“All right, dear, I am ready.  But, if you don’t mind, we might go first to Mercy.  I am anxious about grandfather, and we might see that—­as yet, at all events—­nothing has happened there.”

So they went on the high-hung road along the top of the Brow.  The wind here was of great force, and made a strange booming noise as it swept high overhead; though not the sound of cracking and tearing as it passed through the woods of high slender trees which grew on either side of the road.  Mimi could hardly keep her feet.  She was not afraid; but the force to which she was opposed gave her a good excuse to hold on to her husband extra tight.
