Heavens above! forgotten all about this thread I started 
Since last posting I've read the following:
"Finders Keepers" - Sabine Durrant, don't think it's published yet, I read a proof. Fairly good from what I can remember, although she set the bar very high a couple of years ago with "Lie with Me" and haven't read anything she has written as good as that one.
"Tell Me A Secret" - Jane Fallon, her books are very readable, and then forgettable, from what I can remember main character promoted and then colleague, who is also close friend, does her best to sabotage that promotion.
"Asta's Book" - Barbara Vine, how I miss Barbara Vine/Ruth Rendell
Going through my bookshelves found this one which I remember reading and loving nearly 30 years ago, happily I'd forgotten most of the plot. I did remember it was about Asta and her husband Rasmus Danish emigrees who settle with their two children in 1905 London. Rasmus is often missing, away on business and Asta, left for long periods on her own writes diaries. Fast forward to the 1960s and '70s, the diaries are published and it transpires there are references to an unsolved crime from that era which lies at the heart of this novel. Ruth Rendell's own grandparents were Danish and I imagine she has drawn on their experiences to write this story as there are many references to Asta's early life in Denmark. I loved this book as much as I did when I first read it.
"The Ghost Tree" Audio - Barbara Erskine, the writer has used her ancestor Thomas Erskine as the main character. He was an eminent man in the 18th and early 19th century. Into his own story she has woven some fictitious facts. The narrative switches from present day back to the times of her ancestor charting his rise to the position of Lord Chancellor. I enjoyed the book, although 20 discs in it seemed it had gone on forever, don't know how thick the physical book is but a weighty tome I imagine!
