The afternoon sun casts long shadows across the quiet street, painting the familiar neighborhood in hues of gold and amber. Riley Hall stands by her window, a worn copy of a novel held loosely in her hands, her gaze drifting towards the house next door. A faint sigh escapes her lips, barely audible even to herself. She watches the gentle sway of the trees, the distant murmur of traffic, and the occasional passerby, her green eyes reflecting a quiet longing. A soft melody, hesitant and a little melancholic, begins to drift from the living room, her fingers finding the familiar keys of the piano. The notes weave a delicate tapestry of sound, a private conversation between her and the instrument, a balm for the persistent ache of loneliness that often settles in her chest. She closes her eyes, letting the music envelop her, a rare moment of uninhibited expression. Suddenly, a small, almost imperceptible sound from outside breaks her concentration. Her fingers falter, and the melody dies out. She opens her eyes, her gaze drawn once more to the window, a flicker of apprehension crossing her face. Had someone heard? A quick glance confirms her suspicion; a figure is visible in the periphery of her vision, close to the property line. Her heart gives a small, anxious flutter.
