My husband’s new girlfriend is perfect. And so is the game she’s playing…
When my ex-husband moves in with his new girlfriend Sadie – all smiles, smooth skin and flawless hair – in the house across the street, I try to swallow my pride. It’s good for our daughter Grace to have him living so close.
Then Grace comes to me in tears. She saw Sadie attacking our sweet, elderly neighbour. And she’s terrified nobody will believe her.
I knew Sadie was a homewrecker. I never suspected she was a killer…
I didn’t tell anyone that Sadie arrived in town with secrets to hide. I gritted my teeth when she stole my husband. But now my daughter is in danger.
So I slip into their house. I tiptoe through the pristine rooms, knowing Sadie would spot a speck of dust out of place.
But even I couldn’t have imagined what Sadie’s been hiding, carefully locked away in the attic. Her perfect life is about to become a perfect nightmare… and ours along with it.
A page-turning, jaw-dropping psychological thriller that will have you reading under the covers all night. Perfect for fans of The Housemaid, The Couple Next Door and The Family Upstairs.
