Ahh, and now we have at least a link back to Deeters and those who would wish ill will on Harry & his friends. Harry & Hermione will most definitely have to invite Viktor to their wedding for his providing that one, most useful, insight. I have to wonder, and I'm sure you'll eventually explain, how the control was exercised, but at least the broad parameters of the situation are now appearing. However, the really devilish aspect of an investigation is getting all the details right and nailing the perp and I wish Harry and his team all the best with that one.

Thank you for reading and, again, making excellent points. Yep, there is now an established link back to the Death Eaters, but the man who created the first cognivores is dead. Isn’t he?
Stay tuned!
