Detective Clara Woods arrived at Blackwood Manor through driving rain. The victim lay motionless beneath chandelier crystals scattered across marble. His throat was cut cleanly, yet no weapon remained anywhere. She knelt beside him, noting muddy footprints circling the room. Outside, the gates stood locked against everyone except the killer. Clara whispered his name, realizing everyone inside lied about alibis.
