Have you ever looked at those mothers who seem to be perfect – with sweet little children, a full-time job, a beautiful home – and thought: am I not good enough? Ava has. She’s desperate to become just like them. That’s exactly why I’m here…

‘Don’t worry, I’m here to help!’ I say with a big smile. I can see the relief in Ava Green’s face. She has two beautiful children, a charming husband and a high-flying job. But there is so much stress in the lines around her eyes. She worries she isn’t good enough. I understand.

Before she knows it, I’ve cleaned the kitchen and offered to babysit her two little girls. It’s not why she hired me, but I like to go above and beyond. I’m just glad she didn’t check my application too carefully. Because even before we met, I made sure I knew everything about Ava and her lovely little family…

Her husband never helps out. He takes phone calls at strange times. He’s hiding something – and Ava is close to breaking point. Those poor children.

But everything will be okay. I have plans for Ava. She just has to trust me…
