Rain slammed against the window. Detective Vance entered the room. Heavy shadows hid the corners. Blood soaked the Persian rug. Lady Beatrice lay perfectly still. Her lifeless eyes stared upward. The murder weapon was missing. Thunder echoed through the mansion. Someone had hated her deeply. Footsteps sounded in the hallway. The killer remained very close. Vance drew his service weapon. He turned toward the door. The heavy brass handle turned. A familiar face peeked inside. The butler looked incredibly pale. He wore torn bloody gloves. The butler trembled with fear. He possessed a dark secret. Vance stepped toward the man. Tonight would answer every question.
