It's 1939, and war has broken out. Everything has changed at Highbury House school. There are no servants, for one thing, and the pupils have to help with domestic tasks. Then a boys' school is evacuated to the Romney Marsh, billeted in the same building although, of course, contact with the boys is strictly forbidden. Despite this, Justice soon strikes up a friendship with Henry, a boy who shares her dislike of games lessons. Then Justice's father suddenly goes missing.... Could he be a real-life spy? Can Justice and her friends find her father—before any secrets leak? Book four in the series.
