The old lighthouse keeper found the body at dawn's first light. Inspector Mara Voss arrived quickly and surveyed the grim, silent scene. Blood pooled darkly on the weathered stones near the tower's base. Three guests had stayed overnight, each with secrets to hide. The victim was a wealthy collector of rare, stolen artifacts. No one heard screams, yet someone had clearly killed him. Mara noted the broken window and the missing silver locket. Rain began falling softly, washing evidence into the dark sea. She questioned the butler first, who seemed nervous and evasive. The storm had trapped everyone here until morning rescue arrived.
