The most painful of Evie Cormac's memories have been locked away, ever since she was held prisoner as a child - a child whose rescue captured hearts and headlines. Forensic psychologist Cyrus Haven's mission is to guide her to something near normality. But today, on a British beach, seventeen bodies wash up in front of them. There is only one survivor, with two women still missing. And Evie's nightmares come roaring back.

Whatever happened all those years ago lies at the core of this new tragedy. Because these deaths are no accident. The same dark forces are reaching out, dragging her back into the storm. Evie must now call upon Cyrus's unique skills, and her own, in their search for the missing pieces of this complex and haunting puzzle. But will that be enough to save them? And who will pay for the past?

In this episode Gregory Dobbs chats to Michael Robotham about how he came to be a writer of international crime fiction, the course of developing his two main characters Cyrus Haven and Evie Cormac, and what continues to drive him as a writer.
