Elena heard the knock on the door and hesitated. She wasn’t expecting anyone. She opened it slowly and found an empty envelope on the doorstep. A chill ran down her spine as she noticed a faint, cryptic symbol stamped in the corner. It was a circle with an intricate pattern of lines radiating outward, a symbol she had seen only once before in her grandmother’s old journal. With trembling fingers, she picked up the envelope and noticed a subtle scent of lavender, the same fragrance that used to linger in her grandmother’s study. As she closed the door and turned the envelope over, she felt a strange sense of déjà vu, as if this was the beginning of a puzzle she had to solve—a puzzle that might unravel long-buried family secrets.
