The rain lashed against stained-glass windows while eight guests gathered beside the fading embers of the manor’s great marble hearth. A crash echoed from the winged third floor, breaking the tense lull that had clung to their quiet wine-fogged breaths. Their host Arthur Voss had failed to return from his brief trip to fetch rare aged cognac thirty minutes prior. Young Lila, Arthur’s art dealer colleague, volunteered to climb the curved staircase that led to the third floor’s locked suites. Her sharp, terrified scream split the air moments later, spurring the others to race up the winding creaking wooden stairs. They found Lila huddled behind the busted study door, Arthur’s still-warm body trapped under a heavy cast-iron fireplace andiron block. The study’s heavy iron shutters were bolted from inside, making it a seemingly impossible sealed room murder without a trace.
