A&E profiles the case of the princess and the pauper that disrupted an elite neighborhood in City Confidential: Middleburg -- Pistols, Ponies and Foul Play. Argentinian polo player Roberto Villegas was a self-made man, having constructed a middle-class life from very humble beginnings. Some say his greatest feat was hooking up with arms-trading heiress Susan Cummings. But, in reality, it was his worst mistake. Middleburg, VA, served as setting for this fast-paced lifestyle of horses and wealth. When Cummings shot Villegas in the kitchen of her palatial estate, prosecuters thought the case was sewn up. After all, she admitted to the crime. But, in court, the jury had a much different opinion. A&E interviews both sides of the debate as it takes viewers back to Middleburg for a re-creation of this scandalous murder. ~ Sarah Ing, Rovi
