Kim, initially, didn't know if the plot had worked. She didn't know about the news alert that went off in South Korea, or about the 300 people who rushed to the airport in Seoul, weeping and frantic. But what Kim did know is that she had to quickly return to Pyongyang, taking a convoluted series of flights, and it was in Bahrain where authorities stopped them, having noticed their suspicious travel patterns. "Can I see your passports?" one of the authorities said, and soon Kim and the other agent realized they'd been cornered. The two spies bit down on their cigarettes. The older agent died. But Kim did not. When she awoke, her left hand was cuffed to a hospital bed, an oxygen tube in her nose. Men in combat fatigues stood around her, machine guns cocked.
