Mistress

Benjamin Casper, the first-person narrator, is a White House correspondent and owner of an online newspaper called Capital Beat. He is brilliant and deeply eccentric: his mind races compulsively through movie references, presidential trivia, and obscure facts, a tendency his therapist calls "adrenaline-induced emotional sanctuary." He is also haunted by childhood trauma. At age eight, he came home to find his mother dead from a gunshot wound. His father, a history professor, told him it was suicide, but a detective found Ben's fingerprints on the gun. A juvenile court judge could not rule out suicide, and Ben was never convicted.

The story begins when Ben finishes installing covert surveillance equipment in the Georgetown apartment of Diana Hotchkiss, the woman he loves. Diana, a CIA White House liaison who works for Deputy CIA Director Craig Carney, asked Ben to plant a hidden camera and a motion-activated recorder but never explained why. He finishes by his ten o'clock deadline and slips out via the fire escape. Moments later, he watches a body plunge from Diana's sixth-floor balcony. The woman lands facedown, wearing Diana's clothes, her face obscured. Two women from a nearby car reach the body first and cover the victim's face before Ben arrives. Overwhelmed, Ben flees on his motorcycle before police arrive. A patrol officer stops him for reckless driving, documenting his name near the scene.

Over the following days, Ben reasons Diana would not have asked him to install cameras only to kill herself the same night and becomes certain she was murdered. He realizes going to the police would make him the prime suspect, since he was in the apartment minutes before the fall.

Ben flies to Madison, Wisconsin, for Diana's visitation, where he discovers she lied to everyone back home about her education and career. Her brother Randy reveals Diana was involved with Jonathan Liu, a powerful Chinese lobbyist. On the flight home, Ben's engine dies at nine thousand feet; someone replaced his aviation fuel with jet fuel. He crash-lands and survives with a concussion. Soon after, he receives a text showing Randy dead, with the warning: "Randy couldn't stop asking questions. Can you?"

Ben returns to Diana's apartment to retrieve the surveillance recordings, but both devices have been removed. At his lake cabin, two gunmen storm the house. Ben escapes by turning on the shower as a decoy, sprinting out, swimming to a neighbor's dock, and stealing a Jeep. When he confronts Liu's firm, he is taken to the Chinese embassy, where officials threaten to expose his sealed juvenile records. Later, Liu himself intercepts Ben in a parking garage and, visibly frightened, directs him toward "Operation Delano," a codename referencing Franklin D. Roosevelt's middle name that points to a White House-linked blackmail scheme. Diana's best friend, Anne Brennan, visits Ben and reveals a second secret lover: Alexander Kutuzov, a Russian billionaire oil magnate. Ben breaks into Liu's home and finds him shot in the temple, staged to look like a suicide.

President Blake Francis unexpectedly mentions Diana at a press conference, an extraordinary gesture for a mid-level staffer. The CIA seizes all police files on the case. Detective Ellis Burk, Ben's contact at the Metropolitan Police Department (MPD), shows him crime scene photographs, and Ben notices the dead woman lacks the butterfly tattoo Diana had above her left ankle. The body is not Diana's.

Ben tells Diana's parents, but men ambush him at the airport and warn him to stop. While driving with Burk, gunmen ambush them and kill Burk. Detective Liz Larkin arrests Ben and presents incriminating evidence: his fingerprint on Liu's computer mouse, carpet fibers on his shoes, and Liu's wallet planted in his bedroom. Ben realizes someone anticipated his every move and systematically framed him. Deputy Director Carney offers a deal: silence in exchange for all charges dropped. Inspired by Burk's widow, who spoke at the detective's memorial about having "the strength to do it right," Ben refuses.

A private investigator named Sean Patrick Riley, a former Chicago police officer hired by a missing woman's family, contacts Ben. Riley explains that before disappearing, Nina Jacobs held her mail and set her lights on timers as if preparing for a trip, yet continued going to work, suggesting she was secretly living elsewhere. Ben recalls Nina was tall and brunette with a build similar to Diana's, and that Diana had recently dyed her own hair brunette. He realizes Nina was the woman who fell from the balcony, lured to Diana's apartment and dressed in Diana's clothes.

Professor Andrei Bogomolov, Ben's father's former colleague and a former Soviet defector who worked for the CIA, explains Operation Delano. The original operation was Joseph Stalin's plan to blackmail President Roosevelt at the Yalta Conference. The modern version involves Russia blackmailing President Francis so the United States will stand down while Russia invades the Republic of Georgia, with Kutuzov profiting from wartime clauses in his oil pipeline contracts.

Ben bluffs Kutuzov into confirming a blackmail video exists by claiming to possess a copy, but when he tries the same bluff on Carney, Carney calls it and issues an arrest warrant. Russian operatives chase Ben through Washington on foot and by vehicle; cornered by police and military, the operatives detonate their SUV rather than surrender, killing six officers. Ben then stakes out Anne's apartment and watches a government sedan arrive. Inside, Anne kisses Diana, who is alive, handcuffed, and in a prison jumpsuit. Ben finally understands: Diana is not the president's mistress but the First Lady's lover. The blackmail video is a sex tape of Diana and First Lady Libby Rose Francis, recorded and sold to the Russians by Diana herself. The codename echoes the original operation's rumored targeting of Eleanor Roosevelt's sexuality.

At the Lincoln Memorial, Ben confronts Kutuzov and correctly identifies the video's contents. Kutuzov, wearing a wire to communicate with his team, admits to the attacks that killed Burk and the six officers. Ben has arranged for Riley to call 911 reporting his location, ensuring police converge. Kutuzov's team, hearing the sirens, fears the confession has been recorded, and Kutuzov's own sniper kills him.

Ben crashes a public event where the president is speaking, shouting accusations of Russian blackmail before reporters while withholding the video's specific content. In a private meeting, he reveals the full conspiracy and discovers the president knew nothing: Carney orchestrated the cover-up alone to protect both the president's political future and his own ambition to become CIA director. The president, furious, orders Carney out.

Carney resigns. Diana pleads guilty to treason and receives a life sentence. Ben's charges are dropped, and the president publicly thanks him. In a final revelation, the dying Bogomolov tells Ben the truth about his childhood: Ben's father was a spy for China, and when Ben's mother discovered this, the Chinese killed her. His father framed young Ben by placing the gun in the dead woman's hand after the boy had innocently touched it while hugging his mother's body, because the Chinese threatened to kill Ben if the truth emerged. His father spent his remaining years under house arrest, never letting Ben visit so the boy would never learn the secret. Ben's understanding of his entire life shatters. He runs through the streets crying and laughing, his mind racing through presidential trivia despite his vow to stop, a sign that for all he has endured, he remains irrevocably himself.
