The rain hammered the windows of Blackwood Manor while Detective Elena Marlowe stared at the body sprawled across library floor. Outside, thunder rolled across the dark hills, and somewhere inside the ancient house, a grandfather clock struck midnight thirteen times. Victor Blackwood lay face down beside an overturned chair, his silver letter opener buried deeply between his shoulder blades tonight. Seven guests remained trapped by the flooded bridge, each claiming innocence, each secretly hiding something terrible from their shared past. Elena knelt carefully, noticed muddy footprints leading toward the conservatory, and wondered which guest had washed blood from their hands. "One of you killed him before midnight," she announced calmly, watching faces pale beneath flickering candlelight during the violent storm.
