The Girl on the Train gains a lot from three distinct voices

Rachel, the commuter at the centre of the book, drinks too much and cannot trust her own memory. Corbett plays her without judgement: raw, embarrassed, funny in a bleak way, and determined. It is a sympathetic performance that keeps you on her side even when she is making terrible choices.

The novel switches between three women, and the audio edition uses different narrators for each. That makes the shifting timeline far easier to follow than in print, where the dated chapter headings are easy to skim past.

The middle stretch repeats Rachel's train journeys often, and it can feel slow. Listening at 1.1x helps without losing the mood.

The final hour is tense and satisfying, and the narrators bring the three threads together cleanly.
