Alfred Hitchcock may have said all there is to say about the fallibility of making assumptions about what you see through a window, but, like most important lessons, this one can bear some repeating. To the limited scope of a window frame, the former London journalist Paula
Hawkins, in her debut thriller, “The Girl on the Train,” offers a few additional obfuscations. First, her novel’s protagonist, Rachel, looks out through the window of a moving train on her daily commute. Second, Rachel is your basic hot mess: depressed, unemployed, still in mourning for the death of her marriage and prone to alcoholic blackouts that coincide with critical moments in the tale of a missing woman later found dead. Rachel might as well be wearing a sign that reads “Unreliable Narrator.”
