A letter before action would be a good idea.
I would also remove the word "steal" (however accurate)
"Misappropriation of funds' means the same but looks much more official in a letter
You are welcome - and I am happy to check the letter if you would like
That is fine
I think you use the paperclip!
The only paragraph that needs changing is the embezzlement one.
Change to a more emotive one about how her actions had an immediate impact on x y and z as you were not able to pay them
You are most welcome - good luck
