A woman's seemingly perfect second marriage is rocked by a discovery about the death of her first husband in this twisty psychological thriller from Kate White, the New York Times bestselling author whom Entertainment Weekly called "impossible to outwit."

After losing her husband, Derrick, in what appears to have been a random street crime, thirtysomething Emma has built a new life with widower Tom, who is kind, handsome, driven, and successful. Emma is finally able to feel safe again, both in her relationship with Tom and in the home they've made together on the Connecticut shore.

Then one day a homicide detective shows up at Emma and Tom's door asking questions. Though Emma had been cleared of her husband's murder, it appears that law enforcement is taking another look at her and the case.

What do they know? Are they on the right track this time? And most importantly, will the renewed investigation ruin Emma's chances of a happy life?

With twists and turns all the way to the last page, this fast-paced, expertly plotted novel will have you asking that age-old question: how well do you really know the ones you love?
