Interesting. Very well-written for the most part, though part of it seemed a little brief. The storyline was very detailed and interresting and had far more originality and thought in it than often happens with many L/J fics! I really really liked it! Nice work.
Though I take it, sorry being a little slow here, 'the Black Mansion' is a purcase of Sirius's rather than 'Number 12 Grimold Place'? Sorry just got a little confused (because (large though Grimold is it
is a large town house and by no means a mansion). I'd love to hear more about it actuallly. I always love it when due care is given to the scenery.
Anyway, as said! Great chapter! I'd give it uhh... 10 out of 10.
