Interior designer Deva Dunne just may have hit the jackpot. Sure, her new client Francesco Grandese talks tough and has shady friends, but he has the eye of a connoisseur, and a huge, empty mansion he wants her to decorate.

Deva's boyfriend, police lieutenant Victor Rossi, has misgivings about her promising job - especially when he accompanies her to one of Francesco's dinner parties. After Francesco returns a dish to the kitchen untasted, the chauffeur promptly scarfs it down and drops dead from cyanide poisoning.

Has the killer made a terrible mistake and murdered the wrong person? Or was the dead man the intended victim? The only thing Deva knows for certain is someone present that night committed murder. And it seems everyone - from the dinner guests to the kitchen help - has a motive.
