The clock struck twelve midnight. Rain fell on cobblestone streets. Detective Mara stood alone. She found the body there. Blood pooled on marble floor. A single rose lay nearby. The victim wore evening dress. Her eyes stared at ceiling. No witnesses came forward yet. Mara knelt beside cold flesh. The room smelled of lilies. Someone had cleaned up well. She noticed a torn photograph. A man's face was visible. Mara slipped it in pocket. Footsteps echoed downstairs suddenly. She drew her service weapon. The door burst open wide. A butler stood there trembling. "Madam, you shouldn't be here," he said. Mara ignored his frightened warning. She walked toward the stairs. The killer was still inside.
