Detective Harris arrived at the old mansion just after midnight, rain soaking his coat while lightning split the dark sky. Inside the silent library a body lay beneath the chandelier, one pale hand still clutching a shattered crystal glass tightly. The victim was Lord Ashworth, and every nervous guest claimed innocence while carefully avoiding the detective's steady searching eyes tonight. A single muddy footprint near the French doors suggested the killer had entered from the garden during the violent storm. Harris knelt beside the corpse and noticed a torn scrap of paper hidden deep inside the dead man's coat pocket. The scrap bore only three words written in trembling ink, and those words warned him to trust nobody here tonight.
