The rain fell heavily tonight. Detective Miller entered the room. Blood stained the marble floor. A knife lay nearby, glinting. The victim wore red silk. Her eyes stared at nothing. "Nobody touch anything," he ordered. The butler trembled in corners. Shadows danced across the walls. Someone had opened the window. Cold air filled the space. Miller noticed muddy boot prints. They led toward the garden. "Where is Mister Harrington now?" The maid began crying loudly. Thunder crashed outside the manor. This would be difficult indeed.
