A photograph of two young girls, sisters enjoying the summer sun on a day trip to the seaside. Nothing could be more innocent. But why did it turn up thirty-five years later, clutched in a child killer's hand as she lay dying in her prison cell? Alison Glasby is 25, ambitious and lonely. She's a journalist on the "Sunday Herald" but her career is going nowhere. And despite the best attentions of Scotland Yard murder squad detective John Redgrave, neither is her personal life. Then she gets the chance to work with Fleet Street legend Bill Davenport. Four children were killed in Norfolk in 1969, murdered by Leonie Dellar and her lover. Bill Davenport covered the case and wrote the book - literally. He got close to some of those involved, really close. Glasby was only supposed to do Davenport's legwork, but then she finds the photograph that Dellar had hidden. How did Leonie Dellar get the photo and what made her keep it hidden for so many years? Davenport wants Glasby off the story now. What is it about the murders that he doesn't want her to know? The answer has stayed buried for thirty-five years, but if Glasby wants the truth, she's got ten days to get to it. Davenport won't help her but John Redgrave might - if she lets him.
