Detective Eleanor Vance slowly stepped out of the car and into the cold, relentless rain that battered the empty street. The old Marchetti mansion loomed ahead through the storm, its windows dark, its iron gate groaning as if in warning. She had been summoned here by a trembling telephone call from a woman who had refused to give her name. Now the front door stood open, spilling yellow light onto the wet steps, and no one answered Vance's loud call. She crossed the threshold, her shoes clicking on the marble floor, and the heavy air smelled of dust and secrets. The mistress lay at the foot of the grand staircase, her eyes wide, a crimson stain blooming across her chest. Vance knelt beside the body, noting the overturned porcelain vase, the scattered letters, and the faint scent of bitter almonds. Somewhere above her, a clock ticked with stubborn precision, marking the exact hour when the household's ordinary life had ended. Rain hissed against the tall windows, sealing her inside a house that suddenly felt far too quiet for complete comfort. Vance slowly rose, her face unreadable, and she whispered the words that would begin the long hunt for a killer.
