eir reasons for living here. Who knows what lies behind the pretty curtains and the well-groomed lawns of Mulberry Avenue?

Lucy has a kind and adoring husband, a job she loves as a teacher, and a house on Mulberry Avenue with floaty curtains and the softest bed linen. After her troubled childhood, she knows life will never be perfect, but it's pretty close.

She's also got Amber, right next door. They never run out of things to talk about. Even if Amber's life - with her high-profile job and handsome, wealthy boyfriend - is more glamorous than Lucy's, they share a down-to-earth sense of humour.

But then Amber starts to hint that her life isn't all it seems, and when she comes to Lucy, terrified, saying that she's getting threatening messages, Lucy promises to protect her.

The closer Lucy gets to anyone, the harder it'll be to keep her past to herself. But Amber doesn't have anyone else, and Lucy welcomes her into her home.

Lucy knows all too well that people aren't always what they seem. Sometimes they have secrets. And they'd do anything to keep them. Yet when Amber settles in a little too quickly, Lucy's still sure: she can trust her friend... can't she?

Gripping and unputdownable, The Woman Next Door tells a story about the dark side of friendship, and has a final twist that will shock every reader. Perfect for fans of The Girl on the Train, Friend Request, and Clare Mackintosh.
