Rain hammered the cobblestones as the mansion's lights flickered lonely. Detective Mara entered, her coat dripping, eyes scanning shadows intently. A scream echoed from the library, chilling the night air. Inside, a chandelier crashed, glass scattering like frozen raindrops silently. The body lay across the Persian rug, a crimson stain. Mara knelt, noting the missing cufflink and shattered vase nearby. A cryptic note fluttered from the fireplace, ink smudged tonight.
