'A daring concept executed to perfection' LEE CHILD

A young man stands accused of murder. The evidence is overwhelming.

But at his trial, this man tells an extraordinary story.

It is about the woman he loves, who got into terrible trouble. It's about how he risked everything to save her.

He swears he's innocent. But in the end, all that matters is this: do you believe him?
