Episode 1

The author of global phenomenon 'The Girl on the Train', Paula Hawkins returns with her addictive novel of psychological suspense.

A single mother turns up dead at the bottom of the river that runs through town. Earlier in the summer, a vulnerable teenage girl met the same fate. They are not the first women lost to these dark waters, but their deaths disturb the river and its history, dredging up secrets long submerged.

Left behind is a lonely 15-year-old girl. Parentless and friendless, she now finds herself in the care of her mother's sister, a fearful stranger who has been dragged back to the place she deliberately ran from-a place to which she vowed she'd never return.

Beware a calm surface-you never know what lies beneath.
