Twelve-year-old Flossie is no ordinary ghost — she’s the caretaker of every soul in Highgate Cemetery. And during World War II, even the ghosts aren't safe. Flossie Birdwhistle is the Turnkey at London’s Highgate Cemetery. As Turnkey, it’s Flossie’s job to ensure that all the souls buried in the cemetery stay at rest. Not an easy job for a young ghost, but a task made especially difficult by World War II: London is being attacked every night by enemy bombers, and even the dead are unsettled. When Flossie encounters the ghost of a German soldier carrying a mysterious object that seems to exist in both the living and spirit worlds, she becomes suspicious — what is the officer up to? Before long, Flossie uncovers a sinister plot that could destroy not only her cemetery, but also her beloved country. Can Flossie and her ghostly friends stop the soldier before it’s too late? History collides with the supernatural in this exciting, ethereal mystery from Allison Rushby.
