Rachel Elliot is single and attractive, a director of a successful advertising agency, with a handsome lover, close friends, and a clutch of beloved godchildren. But as her fortieth birthday approaches, so does a whispering fear that she might have missed the point.

Their rise was meteoric. Only a few years before, they had been three friends from Glasgow, trying to survive in a world of danger and dysfunction. Suddenly they were thrust on to the world’s biggest stage, accepting an Oscar in front of the watching world. That night was the beginning of their careers. But it was the end of their friendships. For two decades they didn’t speak, driven apart by a horrific secret. Until now... Their past is coming back to bite them, and they have to decide whether to run, hide, or fight.

I gaze at my husband’s once handsome face, so still and pale in the hospital bed. The doctors say I should keep talking. He might be able to hear me even after the terrible accident that left him fighting for his life. But all I have to whisper to my husband is this: "I know what you did."

The truth is that I loved James with my whole heart. We were soulmates: meant to be together forever. On the morning of our wedding, I had just found out I was carrying his child. But it’s time to tell my side of the story. It’s time everyone knew what happened on that wedding day, on our honeymoon, and on that fateful last drive together. It’s time everyone found out about the secrets and about the threat that loomed over our marriage. It’s time everyone found out who really killed James.
