Voldemort was pleased He didn't have to wait long for the book to glow, signifying a response from Theo. He was, however, displeased when He read the response. Of course, He had to remind Himself that it was perhaps understandable, He had yet to truly show this world His power.
Nott,
I find your lack of cooperation troubling, especially given how well your grandfather served Me. But, I shall humor you this one time. I have neither the time nor the interest to list all of what you have, so let us suffice to say I have no hesitation about informing your employer about the Annia's Tome of Darkness and Morgaine's Lost Knowledge.

I have however sealed it and the Minister will know how to open it. All you need to do is put the envelope in the interoffice mail at the Ministry. She needn't know you are the intermediary.
