dawn and crunchy DO NOT READ THIS - SPOILER ALERT!!!!!
You know what BSL by the end of the book i had forgotten about the psychic and therapist, so now you come to mention it - it was a bit of a red herring, perhaps that was well written in the way you wanted them to be something but they were nothing at all...?
Enid really freaked me out, i got quite uncomfortable reading her story, i found it unbelievable that Clayton carried on living with her after she murdered the love of his life (Patricia) and Todd, how could he just live with their assassin without sneaking off to the polioe (and of course leaving his daughter behind). Enid and Jeremy's motives were to kill Cynthia and Grace because Clayton had left everything in the will to them, thus making the will intestate. Or were you not convinced by that?
I dont think Enid would ever be happy with what she got, and i think she knew she couldnt drive Clayton away because she had this scary hold on him, i dont know some of that may be unbelievable. I liked the subtexts, at first i wasnt sure whether it was Patricia, maybe i had the same 'witness protection' idea as you.
I sussed towards the end that Rolly was giving the money to Tess but it did take a while, i did wonder that he knew more than he was letting on but i too was shocked that he killed Tess and the detective - i guess his motive was tha he didnt want to be found out about the other murder years ago (as clayton would have shopped him if Tess uncovered the truth)
I LOVED the Vince story, even though he was a nutcase i loved the stepfather loyalty towards Jane, he only helped Terry coz of Jane not because of Cyn, i dont think he would have cared otherwise, and how bizarre that he could have gone to the police with what he saw on the night and maybe eased Cyns demons years beforehand.
I did enjoy it and as i say the letter at the end made me cry as it is the type of thing my mother says to me (when she is in a good mood!!!). I would read his books again and could see that as a film. I dont think you are being harsh though, you did enjoy it but i agree there were some pointless elements to it (oh and i thought that the best mate Pam had something to do with it as she kept telling Cyn to forget it - another red herring!)
