The rain drummed against the old mansion’s grimy windows. Fog curled like skeletal fingers through the garden’s dead roses. Detective Mara Vey stepped inside, her boots silent on stone. A single candle flickered where the butler’s body lay sprawled. Blood pooled darkly beneath his outstretched, frozen fingers. The air smelled of gunpowder and something sweetly rotten. A ticking clock echoed through the hollow, empty halls. Footsteps creaked upstairs, though no one had entered yet. Mara’s hand tightened around her revolver’s cold, familiar grip. The killer was here, and they were already too late.
