Two strangers meet on a train. Only one gets off...

A tense, gripping psychological thriller, with Hitchcockian overtones, perfect for fans of Gillian Flynn's GONE GIRL and Sophie Hannah.

Lara Finch is living a lie.

Everyone thinks she has a happy life in Cornwall, married to the devoted Sam, but in fact she is desperately bored. When she is offered a new job that involves commuting to London by sleeper train, she meets Guy and starts an illicit affair. But then Lara vanishes from the night train without a trace. Only her friend Iris disbelieves the official version of events, and sets out to find her. For Iris, it is the start of a voyage that will take her further than she's ever travelled and on to a trail of old crimes and dark secrets. For Lara, it is the end of a journey that started a long time ago. A journey she must finish, before it destroys her...
