In the dusk of an October evening, a sensible looking woman of forty came out through an oaken door to a broad landing on the first floor of an old English country-house. A braid of her hair had fallen forward as if she had been stooping over book or pen; and she stood for a moment to smooth it, and to gaze contemplatively-not in the least sentimentally-through the tall, narrow window. The sun was setting, but its glories were at the other side of the house; for this window looked eastward, where the landscape of sheepwalks and pasture land was sobering at the approach of darkness.
