Now Ruth is trying to rebuild her life and has found a love she doesn't believe she deserves. Aidan Seed is a passionate, intense man who has also been damaged by his past. Desperate to connect with the woman he loves, he confides his secret: he killed a woman called Mary Trelease.

Through her shock, Ruth recognises the name. And when she's realised why it's familiar, her fear and revulsion deepen. The Mary Trelease that Ruth knows is very much alive...
