'Bristling with suspense and elegantly crafted' Patricia Cornwell

'Smart, clever suspense, skilfully plotted, and a lot of fun to read' John Grisham

Kate Moore is an expat mum, newly transplanted from Washington D.C. In the cobblestoned streets of Luxembourg, her days are filled with play dates and coffee mornings, her weekends spent in Paris or skiing in the Alps. Kate is also guarding a secret - one so momentous it could destroy her neat little expat life - and she suspects that another American couple are not who they claim to be; plus her husband is acting suspiciously.

As she travels around Europe, she finds herself looking over her shoulder, terrified her past is catching up with her. As Kate begins to dig, to uncover the secrets of those around her, she finds herself buried in layers of deceit so thick they threaten her family, her marriage - and her life.
