The conspiracy that murdered his wife is no more, but Pendergast will not rest until every last person involved is brought to justice.

Chasing the final conspirator across the moors of Scotland, Pendergast stumbles into a far greater danger than he ever knew existed: the Covenant ("Der Bund" in German), a network of Nazis and Nazi sympathizers that have retreated from public view to influence events on a global scale.

June Brodie and her husband, now living back in Malfourche, are interviewed by a local reporter.

After talking with a homeless person at a soup kitchen, he decides to go after a woman close to Pendergast.

Ned Betterton, the local Louisiana reporter, finds out more information about the Brodie murders, as well as the events at and around Spanish Island that occurred at the end of Fever Dream.

He then conducts an exhaustive search of Esterhazy’s home in Savannah, Georgia, finding nothing of interest.

Pendergast finds out that Helen was born in Brazil, that her native language was Portuguese, and that her great grandfather was a notorious Nazi.

The reporter, Betterton, manages to track down the killers to a yacht, the Vertgeltung (German for “Vengeance”).

The Covenant lures Pendergast to the yacht, where they are holding Constance, tricking him into thinking he has discovered their location.

Esterhazy, fearing for his own life, kills the man in charge, Falkoner, and several other members of the Covenant.

And, finally, how is Corrie going to escape from the Nazi pointing a gun at her and saying, “Auf wiedersehen?” By picking up the action right where Fever Dream ends off, bestsellers Preston and Child sacrifice some accessibility in their 11th thriller featuring unconventional FBI agent Aloysius Pendergast.

Pendergast is still reeling from discovering that the death of his beloved wife, Helen, 12 years before from a lion attack was actually the result of a cold-blooded scheme.

Desperate to learn the truth about the people behind her murder, the agent embarks on a perilous hunting expedition with her brother, Judson Esterhazy.

While in the wilds of Scotland, Esterhazy tells Pendergast a surprising secret that undercuts all the agent's assumptions about what actually happened.

The authors do a good job of showing the lengths Pendergast is willing to go to in his quest, but because the book reads much like the middle of a trilogy, first-timers would do well to start elsewhere in the series.
