Having not been updated in six years this story is sadly "dead".
I'll go on record now as saying, it is truly as shame because it is one of the most interesting plots I have read in my many years of reading HP fanfics. I enjoyed the almost noir quality to the mystery.
Muse is fleeting and real life intrusive, I understand. Too bad that you could not have passed this on to someone who had the talent to take up the torch. (God, all these cliche phrases just jump from my fingers!)
