Hmmm... I Googled and see the Japanese meaning. No, the book wasn't about that!!!! But close.I daren't ask you what it's about. A Dutch Wife has a very naughty meaning in Japanese.
It's a novel about a Dutch woman who, along with her husband, was taken prisoner by Germans for helping Jews during WWII. Put in a different camp from her husband, and seeing a chance for a "better" existence, she ends up working in the camp brothel. So, kinda close to the Japanese meaning.
