A Girl Called Justice: The Spy at the Window : Book 4

Justice Jones, super-smart super-sleuth, is back for her fourth spine-tingling adventure! It's 1939 and war has broken out. Everything has changed at Highbury House school.

The pupils have to help cook, clean and wash up, for a start! Then a boys' school is evacuated to Highbury House, and the girls have to share the building. Justice and her friends are delighted that there are still mysteries to solve, such as: why can they hear voices coming from an empty room? And how can there be a face at the window two storeys up?

Justice must face her biggest challenge yet. Could there really be a spy in their midst?
