Detective Marlowe arrived at midnight, rain hammering the old mansion. The butler waited, pale gloves clutching a silver candelabra tightly. Inside, Lady Whitaker lay sprawled across dusty cold library floor. Her throat bore two delicate punctures, barely bleeding anymore, faintly. Marlowe whispered, 'Nobody touches anything until forensics team arrives here.' Then he noticed a muddy footprint leading toward upstairs balcony.
