The chronicle of Biggles' adventures (and misadventures!) at Malton Hall School. He immediately falls foul of the school bully, Hervey, and his sidekick Brickwell. He recaptures an escaped dancing bear and on a mock army exercise, captures the enemy's flag. After exposing a crook at the local fair and recovering a "stolen" diamond ring from a jackdaw's nest, Biggles and his best friend Smith Tertius cause a local rumpus by making a fake treasure map for their own amusement This sets all the locals off on what became known as the Hertbury Treasure Hunt. But Biggles' most dangerous adventure is sparked off when he goes trespassing in Foxley Wood to gather conkers and he sees Hervey and Brickwell poaching to sell to a local butcher...Illustrated by Leslie Stead.
