The Sunday Times Number One bestselling author of Both Of You and Just Between Us returns with another propulsive thriller that will have you racing to the finish! Smart, wealthy and grounded, Emma has worked hard for her success. When she meets Matthew, a kind, handsome widower, he seems like the icing on the cake.

Initially, Emma's friends are delighted, but as the relationship quickly develops, they worry Emma could be being exploited. She's a rich woman, after all.

While Emma isn't worried about Matthew having so much less than her, she does have one tiny doubt about her new relationship. If Matthew's wife hadn't died, he wouldn't be with her. And sometimes Emma wonders if she is second best. The more she thinks about Matthew's first wife, the more obsessed she becomes with a woman she can never know.

As jealousy and suspicion blossom between Emma and Matthew, events take a darker, dangerous turn. Emma doesn't know who she can trust. Her friends? Her husband? Or even herself...?
