THEIR FIRST MISTAKE WAS INVITING HER IN...

Rose has it all - the gorgeous children, the husband, the beautiful home. But then her best friend Polly comes to stay.

Very soon, Rose's cosy world starts to fall apart at the seams - her baby falls dangerously ill, her husband is distracted - is Polly behind it all?

It appears that once you invite Polly into your home, it's very difficult to get her out again...

The original psychological thriller: a dark, deliciously unsettling drama, perfect for fans of I Let You Go, The Couple Next Door and The Girl on the Train.
