Dear Mrs. Malfoy,

Thank you so much! The polish you sent along is spectacular. I'm sure my grandmother will be thrilled with the results! Your kindness and help with all of this could not be more appreciated.

I look forward to our tea,
Yours,
Pansy

Narcissa,

Of course I won't know with certainty for several weeks at the earliest, but I believe that my project has been successful, especially with the aid of the potion you sent. I've performed a few charms and I am reasonably confident that things have happened according to plan. I'll write again once I am beyond any doubt, but I thought you'd like to have word right away.

Please share the news with Mr. Malfoy if you see fit!

Yours,
Pansy
