The Winged Watchman is her best-known book. It is a true story of how traditional windmills were used by the Dutch resistance for signaling under the noses of German occupiers.[1] Two Dutch boys play a heroic role, carrying a warning message to the first windmill. The signal is then sent rapidly across the countryside by altering the position of the arms of the windmills. The book is based on letters Hilda received from relatives in the Netherlands, and has been praised for conveying an accurate sense of life under Nazi occupation.[citation needed]
