Detective Mara Quinn entered the silent conservatory just after midnight, noticing shattered glass scattered across polished marble floor that evening. The victim lay sprawled beside overturned orchids, his tailored suit stained dark red around his motionless chest area tonight somehow. A single silver candlestick rested nearby, its heavy base smeared with blood and tangled strands of gray hair still wet. Outside thunder rattled tall windows while six nervous guests waited silently in the adjoining candlelit library room without saying anything. Quinn pulled on latex gloves carefully, knowing one careless mistake could destroy crucial evidence before morning investigation began officially tomorrow.
