Well, I have not been here in weeks, but just read everything since.
Tina,
I would love to discuss anything about P. D. James's The Private Patient, but I may not remember all the details.
Steph,
About Rendell's The Water's Lovely, I felt the same as you did. It is very well written, as usual, and I loved reading the book; but as you note, the nasties prevail, the good people die, and are we spoiling this book for everyone else by saying this?
One of my absolute favorites by Rendell was The Keys to the Street.
