Murder On The Graf Zeppelin

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 travellers 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.
