Alison feels like she's losing her mind. She is convinced that her ex-husband Jack is following her. She is certain she recognises the strange woman who keeps approaching her at work.

She knows she has a good reason to be afraid. But she can't remember why.

Then the mention of one name brings a lifetime of memories - and the truth - crashing back...

An electric, page-turning thriller perfect for fans of Louise Candlish, Adele Parks and Erin Kelly.
