The wind was still moaning in the distance, though never a breath of it came near the house of Shaws.

It had fallen blacker than ever; and I was glad to feel along the wall, till I came the length of the stairtower door at the far end of the unfinished wing.
I had got the key into the keyhole and had just turned it, when all upon a sudden, without sound of wind or thunder, the whole sky lighted up with wild fire and went black again.

I had to put my hand over my eyes to get back to the colour of the darkness; and indeed I was already half blinded when I stepped into the tower.
It was so dark inside, it seemed a body could scarce breathe; but I pushed out with foot and hand, and presently struck the wall with the one, and the lowermost round of the stair with the other.

The wall, by the touch, was of fine hewn stone; the steps too, though somewhat steep and narrow, were of polished masonwork, and regular and solid underfoot.
Minding my uncle's word about the bannisters, I kept close to the tower side, and felt my way in the pitch darkness with a beating heart.
The house of Shaws stood some five full storeys high, not counting lofts.

Well, as I advanced, it seemed to me the stair grew airier and a thought more lightsome; and I was wondering what might be the cause of this change, when a second blink of the summer lightning came and went.
If I did not cry out, it was because fear had me by the throat; and if I did not fall, it was more by Heaven's mercy than my own strength.
