The stunning new thriller from the No. 1 Sunday Times bestselling author
They thought they'd got away with it … they were wrong.
Leigh and her sister Callie are not bad people – but one night, more than two decades ago, they did something terrible. And the result was a childhood tarnished by secrets, broken by betrayal, devastated by violence.

Years later, Leigh has pushed that night from her mind and become a successful lawyer – but when she is forced to take on a new client against her will, her world begins to spiral out of control.

Because the client knows the truth about what happened twenty-three years ago. He knows what Leigh and Callie did. And unless they stop him, he's going to tear their lives apart …

Just because you didn't see the witness … doesn't mean he wasn't there.
