The Clue by Carolyn Wells

The old Van Norman mansion was the finest house in Mapleton. Well back from the road, it sat proudly among its finely kept lawns and gardens, as if with a dignified sense of its own importance, and its white, Colonial columns gleamed through the trees, like sentinels guarding the entrance to the stately hall.

All Mapleton was proud of the picturesque old place, and it was shown to visiting strangers with the same pride that the native villagers pointed out the Memorial Library and the new church.
