Beth and Cath are leaving their husbands.
This is a story about two very different women. 
One is wealthy and having an affair with a man who gives her the kind of love that her cold, detached husband does not. 
One is living hand to mouth, suffering at the hands of a violent partner who would rather see her dead than leave him. 

You may think you know these women already and how their lives will unfold.
Beth will live happily ever after with her little girl and her soulmate. 
Cath will go back to her abusive husband. 
And these two women will never cross paths. 

But you will be wrong.
On the 3.15pm train from London to Bristol, Beth and Cath are about to meet and discover they share one shocking thing in common.
