The Sister-in-Law

Don’t miss this totally unputdownable psychological crime thriller, guaranteed to have readers up all night turning the pages! Perfect for fans of Frieda McFadden, Daniel Hurst and Lisa Jewell.

Would you invite a stranger in?

When Megan loses her beloved husband in a tragic car accident, she feels like it’s her own life that has ended. She feels too young to be a widow. Walking around the house that had been their home – so quiet without him – nothing feels the same.

But at his funeral, she sees a person she doesn’t know. The heavily-pregnant young woman introduces herself as Emily, her husband’s estranged sister. She explains how she’s been searching for her brother for years, but – as she bursts into noisy sobs – she knows she’s too late now.

Megan finds herself taking pity on the sister-in-law she’d never met. And quickly Emily becomes more and more a part of her life, even moving into the spare room of her house.

It feels less empty than before, which at first is comforting to Megan. But – even when it’s a relative of the man you loved more than anyone – can you trust a stranger?
