The Chiswick Book Festival broadened its horizons this year, holding an event in The Andrew Lloyd Webber Theatre at ArtsEd for the first time. Chaired by Joe Haddow (producer of the Radio Two Book Club), it featured authors Paula Hawkins and SJ Watson, who have both recieved critical acclaim and bestselling success for their psychological thrillers The Girl on the Train and Before I Go to Sleep. The film adaptation of The Girl on the Train will be released in October 2016 starring Emily Blunt. Can it replicate the box office success of Before I Go to Sleep, starring Nicole Kidman and Colin Firth?
