I have read some great mystery/thrillers this year, and here is another. I don’t want to say too much and spoil this for anyone. Again, as in The Girl on the Train we have unreliable narrators. And again, they are hard to warm to. This is a cleverly constructed novel, with characters who are flawed and often react to their situation badly - rather like real life! I really couldn’t put this down. Highly recommended.
