It is only a glimpse - and it can't have been him - but it is enough to bring back all the painful memories. Why did he kill himself? What was so terrible that he couldn't go on? The thoughts won't leave her alone. Kelly confides in her friend Jack and as theytry to find out more about Dad's past they unearth a confusing mass of inconsistencies and unanswered questions. Gradually they are sucked into a murky world where nothing is as it seems. They are out of their depth; someone is trying to stop them finding out more and they are in real danger. Who is following them? Who can they trust? And why does Gran refuse to talk about Dad?
