You have to feel bad for Iris. Her marriage is falling apart so she's rented Mill Cottage to escape to. Just as she's settling in and getting to know the neighboring Wetherby family, Dom Wetherby ends up dead, murdered. She's drawn into the case almost as a distraction from what's going on in her own life.
The Wetherbys are far from the perfect family they present to the world. There are secrets and jealousies and entanglements. The characters are well drawn, each with strengths and weaknesses. There are several people with motives to kill Dom and enough red herrings to keep me guessing.
The book was maybe a little long and Shaw really loves similes, but it kept my attention throughout. Iris is intelligent and observant but I do wish she had better taste in men. I also appreciated the Christmassy touches.
