Manchester 1849. Elizabeth Gaskell, newly famous author of Mary Barton, visits a young Irish prostitute in Manchester’s New Bailey prison. The girl is about to be discharged onto the Manchester streets, where her old life of poverty and violence await her. Elizabeth is determined to help her, but few people will employ an ex-prostitute from prison. In desperation, Elizabeth writes to Charles Dickens for advice.

Inspired by the real correspondence between Elizabeth Gaskell and Charles Dickens, Elizabeth and Ruth tells the unforgettable story of two very different women whose lives become inextricably intertwined.
