Short Summary

Former Justice Department operative Cotton Malone is drawn into a high-stakes conspiracy when Princess Lysa, sister of the Swedish king, is kidnapped. The ransom demands the Codex Gigas—the legendary "Devil's Bible." Meanwhile, Sweden’s bid to join NATO is blocked by a Czech demand for the same manuscript, a centuries-old war trophy. As Cotton investigates, he discovers that the princess’s husband, John Westlake, was a compromised asset, and that Russian intelligence is manipulating events. The operation leads to a devastating shootout at Stockholm’s Vasa Museum where Stephanie Nelle is killed. In the aftermath, the Codex Gigas is returned to Prague, Russia disavows its agents, and Cotton learns he may have a twenty-year-old daughter.

Full Summary

The novel opens with an epigraph from 2 Timothy 4:7, foreshadowing a story of faith and endurance. The prologue finds Cotton Malone in Atlanta with Cassiopeia Vitt, reflecting on a recent traumatic event that has left them vulnerable. The story then flashes back “Two Weeks Earlier” to Stockholm.

Cotton and Stephanie Nelle arrive in Sweden to assist King Wilhelm after his sister, Princess Lysa, is kidnapped. While walking to the palace, a white Volvo attempts to run them down. Cotton evades the attack, and Stephanie reveals the problem may involve John Westlake, the princess’s British husband.

John Westlake is summoned to the palace, where the king reveals Lysa has been taken by Russian agents demanding the Codex Gigas. Westlake suggests giving the book, but the king wants him to use his Russian business contacts. Stephanie and Cotton enter, repeat old suspicions about Westlake being a Russian spy, and he leaves angrily. Stephanie then briefs Cotton on the KGB’s involvement in Olof Palme’s assassination and a canary trap that identified Westlake as a mole—though the king stopped surveillance to protect the family.

Cassiopeia Vitt begins following Westlake. He checks into the Grand Hôtel, receives a mysterious note, and heads to the Moscow Circus. Meanwhile, Cotton searches the Gamla Stan neighborhood and finds a witness, Lars, who saw the kidnapping. Lars later turns out to be a trap; Cotton is attacked in underground tunnels and barely escapes.

At the circus, Westlake meets Monica Butler-White, an SVR officer who forces him to don a clown costume. During the performance, a real assassination attempt is made on the king and queen, but Cassiopeia tackles the shooter. Westlake and Monica escape in chaos.

Princess Lysa, held at a château, reflects on her faith and childless marriage. She remains unaware that her friend Monica is her handler. Westlake later reveals to the palace that Lysa is an unwitting Russian asset; he took the blame nine years ago to protect her. The king refuses to believe it.

Cotton chases a Volvo through Prague after a law-office shootout. He receives a call from Stephanie, who tells him about Westlake’s confession. During the chase, his car is T-boned, and Cotton is knocked unconscious. He later wakes to find that Russian SVR agent Ivan orchestrated the crash. Ivan reveals that Cassiopeia is in danger and that he wants to defect. Cotton, cautious, agrees to help.

Stephanie examines the Codex Gigas at the Swedish Royal Library. She learns that the Czechs are using Sweden’s NATO bid as leverage for the manuscript’s return. She distracts the SVR with a staged transfer of the book.

Monica Butler-White kidnaps Westlake and forces him to watch as she drowns Lysa in a bathtub. The château is then blown up to destroy evidence. Westlake, complicit, chooses his SVR cover over his wife.

Cotton, Ivan, and Stephanie plan to fly the real Codex Gigas to Ramstein Air Base. The flight is a trap to expose a mole. Two Russian Sukhoi fighters attack the plane. Cotton uses the Øresund Bridge and a container ship to evade a missile, which hits the ship instead. He crash-lands at Karup Air Base in Denmark, unharmed.

Back in Stockholm, the team identifies CIA officer Sandra Koss as the mole. They arrange a meeting at the Vasa Museum with Monica Butler-White. At the museum, a shootout erupts. Monica kills Aleks and Sandra. John Westlake appears, armed. Stephanie Nelle confronts him, unarmed; Westlake shoots her in the chest. Cotton descends from the ship’s rigging and kills Westlake. Cassiopeia shoots Monica. Stephanie dies in Cotton’s arms.

The epilogue shows Stephanie’s private funeral in Atlanta. The Codex Gigas is sent to Prague. Russia disavows its agents. CIA station chief Koger is demoted. Cotton, burdened by loss and the possibility of having a daughter, decides to search for the child he may have fathered twenty years earlier.
