In this ingenious standalone thriller from the internationally bestselling author and “razor sharp” master of suspense (People), a grieving wife is forced to ask: Which is worse—infidelity or murder?

Ellie Faulkner’s world has been destroyed. Her husband Greg died in a car crash—and he wasn’t alone. In the passenger seat was the body of Milena Livingstone, a woman Ellie’s never heard of. But Ellie refuses to leap to the obvious conclusion, despite the whispers and suspicions of those around her. Maybe it’s the grief, but Ellie has to find out who this woman was—and prove Greg wasn’t having an affair. And soon she is chillingly certain their deaths were no accident.

Are Ellie’s accusations of murder her way of avoiding the truth about her marriage? Or does an even more sinister discovery await her?
