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 broken fingernails. Scratches marked the victim's throat. A pearl necklace was missing. Mara photographed everything carefully. The butler arrived downstairs. He claimed he heard nothing. Mara did not believe him. The game had just begun.
