In this story the most powerful man in the world, the president of the United States has to be manipulated and who better to do this than his own wife. So how easy can an enemy nation have if they can supplant the first lady with their own stooge. Thats the premise of "The Second Lady".
Billie Bradshaw is the wife of Andrew Bradshaw, the president of the United States who is one of the most popular women in the world. He beauty and poise makes her the most sought after and photographed lady. So the Soviets hatch a plan to put a look alike in her place. So Vera Vavilova, a small time actress gets a role of her life time to play the first lady due to her uncanny resemblance to Billie.



But there are many hurdles for Vera to pass which includes extensive tutoring and training. She has to understand every nuances and behavior of the first lady, her likes, dislikes, friends, enemies and even sex life. She is coached by Alex Razin, a Soviet agent who slowly develops an intimacy due to close proximity. Every physical feature including a scar due to appendectomy is replicated by plastic surgeons in Vera's body. Wallace describes the training process very well in the book and bulk of the early material is devoted for this.
Anyways Billie is abducted and Vera is supplanted in the White House. She gets in to the skin of the character very soon except for small hurdles like when Billie's pet dog does not recognize her, or when she mistakes an old friend for another. But all in all Vera starts enjoying the power and plans to stay on.
Billie on the other hand is drugged and kept in a secret place. Soon she starts to develop a plan to escape and is aided by Alex Razin. After a lot of intrigue they manage to outwit the KGB and escape to America. They confront Vera and plan to thwart the Soviet plan. But Soviets are one step ahead of them and detonate bomb which kills Razin and one of them. Who survives to take the place next to the President is the million dollar question that the reader asks? This book is not one of Wallace's best works and has lot of loopholes and ambiguity around it. It is difficult to accept an ability of an actress to fool an entire security apparatus and a husband. But still, it is good enough for for a one time read.
