Rain hammered the silent mansion. Detective Mara arrived precisely midnight. The butler opened creaking doors. He whispered she died upstairs. Mara climbed the marble staircase. Blood stained the Persian rug. Lady Hawthorne lay unnaturally still. Her eyes stared past eternity. A broken glass glittered nearby. Someone had staged this perfectly. Mara noticed the missing necklace. Footsteps echoed from the hallway.
