Our house / Louise Candlish.

"On a bright January morning in the London suburbs, a family moves into the house they've just bought in Trinity Avenue. Nothing strange about that. Except it is your house. And you didn't sell it... When Fi arrives home to find a removals van outside her house, she is completely blind-sided. Trinity Avenue has been her family's home for years. Where are all her belongings? How could this have happened? Desperately calling her ex-husband, Bram, who owns the house with her, Fi discovers he has disappeared. The more Fi uncovers, the more she realises their lives have been turned upside by a nightmare of their own making. A devastating crime has been committed, but who exactly is the guilty party? What has Bram hidden from her - and what has she hidden from him?"--Publisher's description.
