Imagine seeing your loving husband on a dating app. Now imagine that’s the best thing to happen to you all week …

When Charlie sees a man who is the spitting image of her husband Oliver on a dating app, her heart stops. Her first desperate instinct is to tell herself she must be mistaken – after all, she only caught a glimpse from a distance as her friends were laughingly swiping through the men on offer. But no matter how much she tries to push her fears aside, she can’t because she took that photo. On their honeymoon. She just can’t let it go.

Suddenly other signs of betrayal begin to add up and so Charlie does the only thing she can think of to defend her position – she signs up to the app to catch Oliver in the act.

But Charlie soon discovers that infidelity is the least of her problems. Nothing is as it seems and nobody is who she thinks they are ... The eagerly awaited new thriller from the bestselling author of The Sunday Girl.
