The rain drummed against the old mansion’s grimy windows at midnight. Flickering gaslight cast long shadows across the abandoned grand hallway. Detective Mara Vey stepped inside, her boots splashing through puddles. A single bloodstained glove lay near the shattered front door’s threshold. The air smelled of gunpowder, roses, and something far worse. Footsteps echoed upstairs, though no one else had entered tonight. A child’s laughter drifted from the locked east wing’s darkness. Mara’s revolver felt heavy as she ascended the creaking stairs. The door at the top stood ajar, revealing a scene of horror. Inside, a body slumped over a chessboard, pieces scattered like tears.
