Frantic to discover lives more satisfying than her own, a forlorn London suburbanite envisions the account of a couple she’s just witnessed through the train window in Hawkins’ chilling, guaranteed debut, in which the line among truth and untruth continually moves like the shaking of a train. 

Rachel Watson—a separated, hopeless alcoholic who’s still frantically infatuated with her ex, Tom—rides a similar train each day into London for her impasse work, one she obviously loses after one such a large number of smashed upheavals. Proceeding with her every day drive to keep up appearances with her flat mate, Rachel consistently gives uncommon consideration to a couple, whom she names “Jess and Jason,” who carry on with an apparently ideal life in a house close to her own previous home. At the point when she sees a flashing demonstration of disloyalty, followed not long after by news that Jess—whose genuine name is Megan Hipwell—has vanished, Rachel is constrained to share her mystery information, getting enmeshed in the police examination, which focuses on Megan’s better half, Scott. Further confusing issues is the way that the night Megan disappeared, Rachel has a cloudy memory of unsteadily staggering past the Hipwell home and seeing something she can’t exactly review. Hawkins flawlessly moves among Rachel’s present-day story as the examination concerning Megan’s vanishing augments, Megan’s own life paving the way to her vanishing, and bits about Anna, the lady for whom Tom left Rachel.
