A message to the thief that stole my wallet

Dear sir/madam,

I had some personal items in my wallet. As you know, the cards have been cancelled so there is not much you can do with it right now. If you haven't disposed of it, could you please send it back to me? You have my address, you can put on the post office and tell them to charge me for the postage.

Thank you very much

Me
PS: Especially the mini booklet with the story of Our Lady of Fatima. That is the most precious thing.
