When the call came it seemed like the answer to my prayers. My career as a voice actor had been over for months and me and my little girl Scarlet were living back at my mum’s place. I felt like a failure professionally—and with Scarlet having problems at school, as a parent as well. So, when I was asked to narrate a new book by disappeared novelist Philippa Roberts I jumped at the chance, even if it meant leaving Scarlet with my ex, Hugo, for a few weeks. Hugo, with his perfect new home and his perfect new girlfriend Saskia. But this isn’t a dream come true. It’s a nightmare.

When single mother Darcy’s son falls from a rope bridge at a local playground, life stands still. She clutches his small, limp body, frozen, until a pair of strong hands push her aside, and she watches as George, a local doctor, saves her son’s life. George, with his twinkling hazel eyes, easy charm and lack of wedding band is almost too good to be true, but coffee becomes lunch, lunch becomes dinner, and soon they can’t go an evening without seeing each other.

This is my first job as a housekeeper, but Evan Warner doesn’t need to know that. It’s the first of many lies I’ll tell him. He just lost his wife, Lola, and now he and his young daughter Jessica are adrift. But no amount of cleaning will rid this house of the secrets that have seeped into the cracks. I never forgave Lola for what she did to me. But I can’t let Evan get away with her murder.

Kit Darling is a maid with a snooping problem. She’s the “invisible girl,” compelled to poke into her wealthy clients’ closely guarded lives. It’s a harmless hobby until Kit sees something she can’t unsee in the home of her brand-new clients: a secret so dark it could destroy the privileged couple expecting their first child. This makes Kit dangerous to the couple. In turn, it makes the couple—who might kill to keep their secret—dangerous to Kit.

My darling little boy Albie adores playing at our new neighbours’ house. And after the terrible year we’ve had, I feel so lucky that we can start over in this perfect place, with new friends who treat Albie like the son they never had. He can’t stop talking about the tree house they’re building him, and the cookies they bake together. But as time passes, something starts to feel wrong. Why don’t they ever open the front door more than a crack? They told me they had no children so who does the small pink tricycle I saw in their hall belong to?
