As midnight neared, the mansion’s heavy oak doors creaked open, letting in a gust of rain and a small figure. Inside, Mrs. Whitlock sat at the large dining table, her hands clasped tightly around a single letter she’d just read. An old floorboard creaked upstairs, making her jump and spill hot tea onto the polished wooden surface of the table. She wiped the mess with a cloth, her eyes darting to the window where a car waited in the rain.
