This is the third "Rosa Thorn" novel I've read. They have the same formula, but this one has the silliest ending.
I've read them in the wrong order chronilogically: I read Green Eye (3rd in sequence) first, then Thorn (1st) then this one (2nd).
This one, as the others, is brilliant for the first 80% of the book, before descending into an improbable and weak (though still annoyingly gripping) ending. Although the other two books had unlikely endings though this one takes the biscuit for farce.
It's a shame, really, because the books are so well-written and engaging. They are just let down by the denouement. Also, probing a little beyond my comfort zone, because I'm not a professional writer or critic at all, but all the characters are so beautifully delinated over a long, smouldering build-up, with the exception of that of the eventual baddie, whose feelings are conveyed in anonymous flashbacks.
I think that I will end up with this author as I did with Reginald Hill; I initially loved the books but ultimately tired of the self-indulgence. I probably won't read another Vena Cork. Well, maybe just one, so see if she can break the mould ...!
