The Family Upstairs

You thought they were just staying for the weekend. They looked harmless enough - with only two suitcases and a cat in a wicker box. But soon things turn very, very dark. It happens slowly, yet so extraordinarily quickly. Now you and your sister must find a way to survive....

London. Early morning, June 2019: on the foreshore of the river Thames, a bag of bones is discovered. Human bones. DCI Samuel Owusu is called to the scene and quickly sends the bag for forensic examination. The bones are those of a young woman, killed by a blow to the head many years ago. Also inside the bag is a trail of clues, in particular the seeds of a rare tree which lead DCI Owusu back to a mansion in Chelsea where three people lay dead in a kitchen. Four deaths. An unsolved mystery. A family whose secrets can't stay buried for ever.
