The Night Horseman by Max Brand

It had been hard to gauge the falling of night on this day, and even the careful eyes of the watchers on the Cumberland Ranch could not tell when the greyness of the sky was being darkened by the coming of the evening. All day there had been swift alterations of light and shadow, comparatively speaking, as the clouds grew thin or thick before the wind. But at length, indubitably, the night was there. Little by little the sky was overcast, and even the lines of the falling rain were no longer visible. Before the gloom of the darkness had fully settled over the earth, moreover, there came a change in the wind, and the watchers at the rain-beaten windows of the ranch-house saw the clouds roll apart and split into fragments that were driven from the face of the sky; and from the clean washed face of heaven the stars shone down bright and serene. And still Dan Barry had not come.

After the tumult of that long day the sudden silence of that windless night had more ill omen in it than thunder and lightning. For there is something watching and waiting in silence. In the living room the three did not speak.
