I’m Richard Vernon Porter. I’m sixty-eight years old, retired for four years, and I’ve lived in Dallas long enough to know that money changes the air in a room before it changes anything else. Before retirement, I spent thirty-eight years as an Assistant United States Attorney specializing in financial crimes and fraud. I’ve watched con artists swear oaths with their fingers crossed. I’ve listened to corporate executives cry on the stand when they realized their private emails were now public. I’ve walked juries through spreadsheets so complex they looked like modern art, then showed them the one number that mattered: stolen.

I thought I’d seen every con imaginable.

Turns out the most dangerous ones don’t come from strangers in parking lots. They come to Sunday dinner wearing a designer dress and a practiced smile.
