Langdon and Katherine arrive at the U.S. ambassador’s residence in Prague, Petschek Villa, a heavily secured estate with a dark history of Nazi and Soviet occupation. Langdon recalls the villa’s wartime role as a planned “trophy case,” with furnishings marked for future display after a Nazi victory.

A U.S. Marine escorts them inside, where an older staffer settles them by a fire with coffee, pastries, and fresh chocolate chip cookies while Ambassador Heide Nagel finishes a call. Langdon privately jokes about being hosted well even if the situation feels dangerous.

Upstairs, Nagel looks out over the snowy grounds and reflects on how her early optimism has eroded. She confirms the official cover story: Captain Janáček framed two Americans and then died by suicide, and she has forced ÚZSI to keep its distance from Crucifix Bastion and recover Janáček’s body only from below the ravine. With the immediate crisis managed, Nagel turns to the unresolved problem of Langdon and Katherine, receives two documents from Mr. Finch, and heads downstairs.

While waiting, Langdon warns Katherine they should stop discussing their theories inside the residence because they may be monitored, realizing he may already have spoken too freely in the limo. Trying to occupy themselves, Langdon leads Katherine into the formal dining room and flips over one of the antique chairs.

On the underside, they find a faded Nazi catalog sticker with a numbered tag, the Reichsadler, and a swastika. Langdon explains the embassy left the original markings as a reminder of the war’s horrors. At that moment, Nagel appears behind them, unsmiling, and tells them that if apologies are owed, they are hers: the U.S. government owes them “one hell of an explanation.”
