As I turn the rusty key in the lock of the house I grew up in, memories flood back. None of them happy. I never told anyone why I left home twenty years ago, and all I want is to sort out Dad's funeral as quickly as possible. Now I'm trapped here, the only witness to a terrible incident that has left an eight-year-old boy fighting for his life. But after a lifetime trying to forget my past, I don't know if I can trust my memory, or be totally sure of what I saw today. Sorting through Dad's things one night -- shopping lists in his curly handwriting, piles of old newspapers, dusty sports trophies -- I think I hear the back door handle rattle. I tiptoe downstairs, past an open window I'm sure I locked. And a figure darts across the overgrown garden. Someone is watching me. Someone who knows 'm the only one who saw what happened to little Ethan or could they know the real reason why I left? Either way, I'm certain that coming back was my biggest mistake. I can't leave, but the longer I stay, the more danger I'm in.
