The Girl on the Train is a psychological thriller set in London and its outskirts. It is bestseller book, so I thought I would give it a try and see what I thought myself.
It is narrated from three different perspectives, thought only one of them belongs to the protagonist - Rachel. She got divorced some years back because of a drinking problem that she developed, which she still has not overcome. Everyday, she takes the same train to go to London and back, even though she also lost her job a couple of months ago because of the same problem. While in the train, every time she observes the houses she passes by, though there's two in particular that she is interested in: her old house, where she used to live with Tom (her ex-husband) and where the latter still lives with her new wife; and one on the same street where a couple that seems perfect to Rachel lives. One day, the woman in the perfect couple disappears.
