Rain hammered the cobblestones as the manor's lights flickered lonely. Detective Marlowe arrived, his trench coat dripping with suspicion deep. Inside, the ballroom lay silent, a shattered chandelier glimmered cold. A body lay beneath the grand piano, eyes wide open. Marlowe examined the scene, noting a single crimson rose near. The clock struck midnight, echoing the ticking of hidden secrets.
