The rain battered manor, muting footsteps along marble corridors tonight. Inside, moonlight stitched silver patches across a locked drawing room. A body lay beneath the chandelier, eyes wide with disbelief. The clock chimed three times, each note cruel and deliberate. Detective Mara Hale arrived, coat fluttering, notebook ready for confession. She stepped over velvet rope, surveying footprints and shattered vase. The victim wore a smile that did not belong here. Whispers traveled corners like autumn leaves, confessing nothing, revealing everything. Muffled thunder applauded as suspects gathered, eyes calculating, nerves taut. In her notebook, clues whispered themselves, stubbornly refusing to cooperate. Tonight, the mansion would tell truths it preferred remaining silent. Someone among them wore guilt like perfume, intoxicating and close. The door clicked shut, sealing secrets behind a velvet moon. In stillness, the killer's shadow stretched, watching everyone pretend silently. Only the rain understood the mathematics of motive and misdirection.
