I was saving my stars this week for The Girl on the Train, which lives up to its media acclaims. The girl on the train is not a girl, but a grown woman who is a black-out alcoholic and who nurses an unhealthy obsession with her ex-husband and his new family. So when she fixates on another couple, neighbors of her husband’s, her motivation is suspect. And so she is snared into a police investigation and her unreliable memories put her in a vulnerable position. A twisty plot and a fine portrait of a psychopath reminded me strongly of Gone Girl, but with an entirely different direction — and with a British accent.
