Cath’s latest novel The Girl in the Green Dress tells the story of the murder of a transgender teenager, Allie, and asks how far would you go to protect your child – what if you suspected them of involvement in a terrible crime? Is your duty to keep them safe and shield them? Or to respect the law and make them take responsibility for what they’ve done? The parents involved have very different responses to the dilemma. Responses that put the search for truth and justice, for Allie and her family, in jeopardy.
