Rain hammered the old mansion. Detective Harris arrived after midnight. A body lay downstairs motionless. Blood stained the Persian carpet. The butler stood nearby trembling. Nobody spoke for several minutes. Lightning revealed a broken window. Someone had entered without permission. Harris examined the cold corpse. The victim was Lord Ashworth. His throat showed deep cuts. The weapon remained still missing. Servants gathered in the hall. Each face hid private secrets. Harris knew the night mattered.
