"The Girl on the Train" has more fun with unreliable narration than any chiller since Gone Girl…Paula Hawkins…[is] no slouch when it comes to trickery or malice…Ms. Hawkins scrambles the timing of scenes, with Megan gone in one chapter and then present in the next. She also shifts well among her narrators´ points of view to keep the reader on edge, and only as the book progresses do these different perspectives begin to dovetail. Scrambling a story is easy, but it´s done here to tight, suspenseful effect.
