The Lone Star Ranger by Zane Grey

After supper Duane stole out for his usual evening's spying. The night was dark, without starlight, and a stiff wind rustled the leaves. Duane bent his steps toward the Longstreth's ranchhouse. He had so much to think about that he never knew where the time went. This night when he reached the edge of the shrubbery he heard Lawson's well-known footsteps and saw Longstreth's door open, flashing a broad bar of light in the darkness. Lawson crossed the threshold, the door closed, and all was dark again outside. Not a ray of light escaped from the window.

Little doubt there was that his talk with Longstreth would be interesting to Duane. He tiptoed to the door and listened, but could hear only a murmur of voices. Besides, that position was too risky. He went round the corner of the house.
