Rain slicked the manor steps as midnight swallowed every lantern. Inside, Colonel Voss lay dead beside the shattered clock. No one had heard the scream, though everyone claimed otherwise. Detective Mara Vale arrived, carrying questions sharper than apologies. The guests watched her enter, each hiding mud, fear, and alibis. A single red glove rested on the corpse's still hand. Mara noted it belonged to someone wealthy, careless, or desperate. Then the house lights failed, and another body dropped.
