A pulse-pounding locked-room murder mystery set on a zeppelin bound for Brazil from Nazi Germany--think Murder on the Orient Express in the air..."The ingenious [solution] is only one of many pleasures in this powerfully atmospheric novel" that can be easily devoured in a single night (The Times). In 1933, a zeppelin leaves Nazi Germany, chartered to cross the Atlantic and land in Rio de Janeiro, Brazil. It's a modern luxury holiday for travelers performing loyalty to a radicalizing Germany--until a murder in the airship's washroom exposes the rot beneath the Reich. Police Detective Bruno Brückner happens to be on board and is drafted to investigate, only to discover that the "Good Nazi" victim was a total fabrication. Hidden among his belongings is a stash of banned "degenerate" material. It seems everyone on board has something to hide, and even beyond Germany's border, no one is safe to voice what they may know. There are no good Nazis, not on this flight and not in the Fatherland. From the wealthy baroness to the antisemitic doctor, every passenger wears a mask of complicity or survival, and in this sky-high pressure cooker the truth is more dangerous than the fall. As Brückner peels back their lies, he uncovers a startling story of fake identities, queer love, and revenge, where nothing is as it appears, until finally the secret of the "good Nazi" is revealed... Giving fascinating insight into the "twisted psyche of fascists" (The Critic) and 1930s queer culture under Nazi rule, this thrilling historical mystery will keep readers hooked until the final page.
