Confessions on the 7:45

Confessions on the 7:45 is Lisa Unger's 2020 psychological thriller about Selena Murphy, who shares secrets with a stranger during a stalled train ride and then finds her private life invaded by the consequences. Unger's official FAQ says the book is in development at Hulu, and Park Row's English hardcover uses ISBN 9780778310150.

The premise has the clean snap of a classic suspense setup: tell the wrong person the right secret, and the world starts answering back. Unger builds from domestic distrust into a wider pattern of identity, performance, and manipulation.

Read it before any Hulu adaptation if you want the novel's layered point-of-view structure first. A screen version can make the train encounter sharp and cinematic; the book's strength is how slowly it makes Selena doubt the boundaries of her own life.

Selena Murphy is a commuter, wife, and mother whose private suspicion becomes dangerous after she says too much.

Martha is the stranger on the train, and her intimacy feels both comforting and too convenient.

Graham is Selena's husband, whose behavior starts the first confession.

Geneva is the nanny whose disappearance changes the story from marital suspicion into a larger mystery.

No. 1 - Hulu development path. Unger's official FAQ identifies Confessions on the 7:45 as in development at Hulu.

No. 2 - Strong thriller hook. The book gives adaptation readers a clear one-sentence premise without becoming simple.

No. 3 - Modern domestic suspense. Marriage, childcare, money, and surveillance all become part of the plot.
