Rain hammered the decaying Hawthorne mansion like impatient fingers tonight. Detective Mara Quinn entered, tracking mud across cold marble floors. The host, Julian Crowe, lay sprawled beside overturned champagne bucket. Blood mixed with Dom Pérignon, fizzing faintly beneath chandelier light. Six guests watched silently, each clutching secrets behind trembling smiles. Quinn noticed the clock stopped at precisely midnight, deliberately smashed. Someone had wanted everyone to remember this exact moment forever.
