I'm guessing it's a preprint, but any ideas?

On 11st of August, I send Imelda Staunton ( the amazing actress who plays Dolores Umbridge in the Harry Potter movies) a LOR and SASE, and today, 18th October, I got a reply!!! I sent to a via venue address, and it was only valid until the end of September or something, so no point posting it now. :...
