Heavy rain poured relentlessly on the old deserted manor house as the detective arrived to find a body lying there. Inside the dimly lit study the victim lay sprawled across the floor with a knife protruding from his back dramatically. Bloodstains covered the expensive Persian rug under the dead body indicating a violent struggle had taken place earlier that night. The detective carefully examined the crime scene looking for crucial clues that would help him identify the mysterious killer soon. Outside thunder crashed loudly as lightning illuminated the dark sky creating an atmosphere perfect for solving this puzzling murder case.
