Second Lady
A Cold War political thriller by Irving Wallace built on a body-double premise: Soviet intelligence trains a woman to impersonate the American First Lady and swaps her for the real one, who is held captive. The story follows the deception and the growing suspicion of those closest to the First Lady as the impostor tries to hold up under intimate scrutiny. It is a plot-driven suspense novel of the kind Wallace was known for, trading on espionage, mistaken identity, and the tension of a switch that could unravel at any moment. A brisk read anchored in the superpower paranoia of its era.
