A twisty, high-stakes thriller in the breathless, page-turning style of Ruth Ware, Lisa Jewell, and Claire Douglas, in which nothing is as it seems and saving the day is only the beginning.

Claire Fitzroy was on the way home to London when her train from Manchester was hijacked by a group of armed men. In one terrifying moment she faced the starkest of choices: to passively stand back or act and fight backknowing that with either choice, she could die.

With nothing to lose, the middle-aged art lecturer gathered and led a squad of passengers who, against all odds, overcame the hijackers and saved hundreds of lives. But what at first looks like heroism may play out very differently in the courts of law and public opinion. Especially when you have the blood of two men on your hands.

Opinions are heated and divided. Was she a selfless and quick-thinking hero? Or an attention-seeking vigilante and unrepentant murderer? Until now Claire has remained silent. Now, she's finally speaking out about what happened that morning on the 10:12.

But is it the whole story?
