Hello! I am a book editor with a limited background in French. An author I'm working with has a character that uses French phrases here and there.
This is how he has this phrase written:
"Mon Petite mystere," she said. "Je ne voulais pas te trouble!"
I know there should be no "e" at the end of "Petite", because she is speaking to a man. I am not sure how to order the last part. It may be correct as it stands, but I'm not sure.
Indeed, there should be no "e" at the end of "petite", as she's speaking to a man. And even if she were speaking to a lady, it would have been "ma petite mystérieuse".
Now for the last part: it just misses a "r", as the verb should be in its infinitive form.
=> "Mon petit mystère," she said. "Je ne voulais pas te troubler".
