She’s in your house. She knows your secret.

Mellie’s future mother-in-law bursts into the bridal suite, a piece of paper clutched in her hand. ‘I know your secret,’ she says, a satisfied smile on her face. ‘And I will not let you marry my son.’

Two months later, anxiety twists in Mellie’s stomach as she watches the taxi arrive. She knew her mother-in-law would move in after her stroke, her husband Henry had insisted on it. But now they’re under the same roof, she knows she’s in danger…

Because locked is the attic is a piece of paper that could destroy everything. And Mellie knows that Pauline will expose her secret.

As Pauline rests, Mellie frantically searches the house for the key to the attic. But when she finds it and starts tearing through boxes of papers, her blood runs cold at what she finds. Hands shaking, she tries to make sense of the words in front of her, realising with a bolt of terror that Henry has his own dark secret. One that could destroy her.

Then she hears footsteps downstairs. The doctors said Pauline would be bedbound for weeks, but what if they were wrong? Neither woman knows what the other is truly capable of, and just how far they will go to protect their secrets. But who will make it out of this house alive?

An unputdownable and addictive thriller that will leave you on the edge of your seat. Packed with twists, this psychological thriller is perfect for fans of Freida McFadden’s The Housemaid, The Girl on the Train and Colleen Hoover’s Verity.
