Every Monday, I meet my writing group in a warm, lively bar to drink a glass of wine or two and share our work. It’s the highlight of my week. I don’t go out much, otherwise. For the last ten years, every time I’ve relaxed, the messages have started again. The black hearts. They’re a warning to remember, as if I could ever forget. Whoever sent them wants to hurt me. They’ve lost me jobs and boyfriends. Is it any wonder I like to hide in fiction?

My husband is lying. The minute he came home with alcohol on his breath and unable to look me in the eyes I knew it. We used to be in love–the intense ‘I can’t be without you for a second’ kind. Where it hurts deep to be apart. But now, we’re the couple that keep secrets from each other. We hide the truth. He thought I wouldn’t find out. I’m a detective–it’s literally my job to uncover clues and solve mysteries. I know what he did. And now I’m sitting here, in a police interview, being asked the question ‘did you kill her?’ to which I utter one life-shattering word: ‘yes.’

Noel never should have been released from prison.

That a single brush of his hand makes her heart flutter. A knight in shining armor who will finally lay to rest the twisted secrets in her past.

The moment I first gazed into Alex's soulful gray eyes, I knew I'd met the man I wanted to spend my life with. And I was right.

And she’s still clueless about what happened that fateful night.

My husband is dead. I attended his funeral. I watched his casket be lowered six feet into the ground. (Actually, it may have been only five feet, but that still seems like more than enough.) And then we ate an array of finger sandwiches and deviled eggs and miniature beef wellingtons that cost more than my first car. My point is, Grant is gone. And so are all his many, many deep, dark secrets which I never really ever bothered to ask him about. He is never coming back.

I gaze across the candlelit table into the eyes of the man I love. It’s our anniversary dinner, a celebration of our marriage, of how far we’ve come.
