Question: summary of the novel the girl on the train by paula hawkins

title: The Girl on the Train (novel)
text: The film rights for the novel were acquired in March 2014 by DreamWorks Pictures and Marc Platt Productions , with Jared Leboff ( a producer at Marc Platt ) set to produce . Tate Taylor , who directed The Help ( 2011 ) , was announced as the director of this film in May 2015 , with Erin Cressida Wilson as scriptwriter . In June 2015 , British actress Emily Blunt was in talks to portray Rachel . Author Hawkins said in July 2015 that the film 's setting would be moved from the UK to the US . The film began production in the New York City area in October 2015 . The film was released on 7 October 2016 . It remains mostly faithful to events in the book , apart from Rachel 's realisation of the truth of Tom 's accusations of her behaviour not being triggered by her own efforts , but through a chance meeting with the wife of Tom 's former manager , who reveals that Tom was actually fired from his job because of his numerous affairs at the office , rather than Rachel 's having a violent breakdown at a party . ( In reality , Rachel simply drank too much and passed out in a guest room , until Tom made her leave . )
