The Last One to See Him

I look at the wedding photo on the wall and my heart freezes as I recognise the groom. I spent the night with him, just a few days ago. I had no idea he was married. And now he is dead…
I feel my new friend Harper’s eyes on me as I try and make myself comfortable in her living room while our little boys play together. But when she leaves the room to get cupcakes out of the oven, I let out the breath I’ve been holding. Does Harper know who I am? That I’m the woman who spent the night with her husband? The last person to see him alive?

She was so excited to invite me and my son Dex over. I thought it was because of our boys. But now I wonder…
How much does she know about me and my past? How long have I been in her sights? And did she plan for me to meet her husband, the night he was murdered?
