I am a writer. I have written 7 or 8 novels, all of them, as yet, unpublished although I have self-published 3 of them. My latest novel includes two characters who are from Minorca.
Felipe is around 30 years old. He has a slender moustache and a broken nose. He is capable of murder.
Maria is around 25 and is beautiful with olive-shaped eyes and black, lustrous hair.
I need to have them speaking English but with a Spanish accent and I have tried to use little inflections to remind the reader that the person speaking is Spanish.
My immediate concern is this: I want Maria to confess to someone, 'The cat is out of the bag.' Meaning, Okay, you have found me out.
How do you say this in Spanish?
Thank you in anticipation.
