I have reviewed a few titles and don't know if they are helpful - i enjoyed Russell H in grimm and honestly never noticed him in his other works - but for me only it was his interpretation of the character - inflection and intonation that was the killer of this story - i just found it hard to listen to the tone of his expertise and arrogance (character traits) - the bone collector as a story is very interesting as a nemesis type crime story - but easy to understand audience decline - my $0.02.
