Hi Claire - Thanks for that. It is interesting to think about the different approaches readers have. I like to look for clues, but I'm not very good at piecing it all together. In one way, it's good to 'solve the case' just before the reveal, but in another way, that can spoil the story. Kate Morton is brilliant at the unexpected twists. Once all is revealed, I feel like I want to go back and read it again to see how she layered everything.
The novel I'm writing sounds a bit like yours in that there are some mystery elements. I've already embedded some clues, but need to work some more in. Hard to know if they work until it goes out to beta readers. Thanks for your comments :)
