Flossie Birdwhistle is the Turnkey for Highgate Cemetery in London, a job that involves making sure that everyone buried in the cemetery is resting peacefully. But, seeing as it’s the middle of World War II, Flossie, a twelve-year-old ghost, has noticed some unrest from the spirits. However, she feels she has things under control. That is until she spots an SS soldier ghost up to something suspicious.

As Flossie investigates the soldier’s appearance, her worst nightmares are confirmed; the soldier has found a way to give information to the living and the Nazis’ plan to use the information in the worst way possible.

The Turnkey is an interesting paranormal mystery with an historical bent that will intrigue readers aged 9 up.
