The term traditionally referred to a lure—in fiction, usually a sexy female agent—which enemy operatives couldn’t resist. Think Vesper Lynd’s seduction of James Bond in Casino Royale, or her real-life counterpart, Anna Chapman, the redheaded KGB agent who worked undercover in New York and then, after she was caught by the FBI and deported back to Russia, began a second career as a Facebook lingerie model.
