Mary Louise in the Country by L. Frank Baum

That night Josie resumed her watch of Cragg's cottage. She did not trust to the shadow of the tree to conceal her but hid herself under the bank of the river, among the dry stones, allowing only her head to project above the embankment and selecting a place where she could peer through some low bushes.

She suspected that the excitement of the previous night might render the old man nervous and wakeful and send him out on one of his midnight prowls. This suspicion seemed justified when, at eleven-thirty, his light went out and a few minutes later he turned the corner of the house and appeared in the path.
