The rain lashed against the cracked window of the old manor house as Detective Miller carefully examined the dead body. Blood stained the expensive rug near the fireplace where his golden watch lay broken and useless beneath the dark shadow. Her soft footsteps echoed through the hall before she entered holding a trembling letter that revealed the truth about him. She dropped the note onto the dusty floor, weeping bitterly as she confessed that her lover knew who killed him.
