Fog hung heavy over the manor’s dimly lit courtyard tonight. The clock struck midnight, echoing through empty hallways of gloom. A scream shattered silence, and a candle flickered out suddenly. Detective Marlowe arrived, trench coat dripping, eyes scanning shadows carefully. The body lay sprawled, a crimson rose clutched tightly in. Whispers rose from witnesses, each claiming innocence, yet eyes glimmered. A storm brewed outside, rattling windows, masking hidden truths deeply. Marlowe knelt, examined footprints, noting a single, anomalous tread carefully.
