I look into baby Fern’s crib, and my heart pounds. I’m her nanny, I was supposed to keep her safe. I hear the police downstairs, and the next words I hear make my legs buckle underneath me. ‘It was the nanny. She’s guilty’.

When I first walked into Jake and Megan ’s immaculate home, I felt totally at ease. Sitting in the crisp white living room, they held hands and talked lovingly about their baby girl, Fern .

As the weeks passed, I began to think I’d made a mistake in taking the job. Jake was overly friendly from the start, watching my every move and always offering to drop me home, even though it was out of his way. And Megan seemed to take pleasure in telling me off in front of her husband, blaming me for things I hadn’t done.

The first time I heard the Haringtons arguing behind the door to their bedroom, I heard my name mentioned, and then they went silent. I should have left right there and then.

Now, as I stand accused of something terrible, my whole past is revealed and the Haringtons admit to knowing every detail about why I was sacked from my last job. We all have secrets, but little do they realise, I know theirs too…

With twist after twist, this is perfect for fans of The Housemaid, The Perfect Marriage and The Girl on the Train . A gripping thriller you don’t want to miss!
