It’s a hectic night in the kitchen of the swanky restaurant where billionaire Eric Vaughn is enjoying dinner with business associates. No one notices a mystery figure spray a substance onto one of the meals. The tainted dish is delivered to Vaughn’s table. Moments later, Arthur Felder, a wealthy venture capitalist, keels over after a few bites of his dinner. Elsewhere, Beckett oozes sexy as she tries to lure her mystery writer boyfriend into the bedroom. Too bad Castle is super-involved in a heated video game match with a kid from India. Beckett is stunned. Has her relationship with Castle hit a plateau? More on that later.
Castle is impressed when he sees Eric Vaughn at the murder scene. The guy is number eight on his “last supper list.” That’s a rundown of people in history you’d like to have at your last meal. Castle’s guests include Lincoln, Einstein, Ian Fleming, John Lennon, Joan of Arc, Sinatra… Oh, and Beckett’s invited, too. Speaking of Beckett, she’s also awed by the charming billionaire in the room. Vaughn says he’s been doing business with the victim for years. Castle notices that Beckett may be thinking about putting this guy on her last supper list, too.
A busboy, Cory Harrison, tells Ryan about a short guy he didn’t recognize brushing past him in the kitchen. It could’ve been the killer. A waiter lets the team know that he messed up his dinner order. The victim was supposed to get the squab. Instead, he was given the poisoned quail. Felder wasn’t the intended target. Eric Vaughn was. The billionaire knows that whoever was trying to kill him is still out there. He wants Beckett… for protection, that is. Castle is understandably jealous. He can’t believe the department is forcing Beckett to hang with some womanizing rich guy against her will. That never happens, right?
