A brilliantly twisty new thriller – perfect for fans of Lisa Jewell

Louise has had to watch her husband, Andrew, start a new family in the four years since he left her. The ‘other woman’ is now his wife – but Louise isn’t ready to let Caz enjoy the life that was once hers, or to let go of the man she still loves.

As Louise starts to dig into Caz’s past, the two women’s pretence of civility starts to slip. But in trying to undermine each other, they discover more about the man they both married.

And when Andrew is murdered at a family party, both women are found standing over the body.
