Everyone Is Lying

This was a nice little psychological thriller. Maybe a little slow to start off, but when the pace picks up, it's game on.
Our protagonist is Alexandra, an aesthetics practitioner. She has it all; a successful business, a townhouse in Brighton, a husband and two children. She also has a secret past, and someone is keen to remind her of it.
There are one or two creepy moments in the book, such as the arrival of the first origami bird, and that constant feeling Alexandra has of being watched.
