He'd envisioned a dusty library filled with books, but his sister, Beatrice, had inherited the family's crumbling mansion. Instead, the will bequeathed him a vintage sports car. A sleek, red Ferrari, gleaming under the garage's fluorescent lights. He ran a hand over the polished hood, his pulse quickening. He felt a surge of energy, a need to rev the engine and feel the wind in his hair. He hadn’t felt this energized in years.
