Not a word to anyone about this! I locked this girl away in the attic.
This sounds illegal. You're joking right?
In answer to your questions, "No" and a resounding "No."
What you're describing is illegal. This could end up with severe legal consequences for you. I would advise you to free her immediately.
No worries, I've got her handcuffed to the radiator.
It's important that you release this girl immediately. Keeping someone locked in the attic is illegal with very stiff legal consequences.
