'A belter of a thriller. Creepy, convincing, it kept me gripped and guessing' Peter James
A twisty and chilling thriller about a woman who did one bad thing when she was young... and must now suffer the consequences.

She thought she'd got away with it. She was wrong.

Hannah Godley is an agony aunt on a London radio show Queen of Hearts. She's warm and empathetic; a good listener. Her catchphrase is: Always be kind. But when a stranger phones in to tell a tragic story about her brother who killed himself after he was the victim of a terrible prank by two people, Hannah goes cold. Because she remembers Diane's brother well. In fact, all these years later, he still haunts her dreams. All because of that one bad thing she did when she was young...

Is Diane just a sad, lonely woman looking for a friend, or does she know what Hannah did, and is looking for revenge? Because as Diane insinuates herself into her life and family, Hannah is going to discover that you can never truly escape that One Bad Thing you did – sooner or later, you're going to have to pay the price...
