The Mystery of the Broken Gargoyle World War 1. England is under siege. Zeppelin attacks are something to be feared, especially in and around London. In the north of the country, where this story takes place, things are quieter. Two Boy Scouts, fast friends, while working on their Astronomy badge, uncover a secret German plot to assassinate a brilliant scientist who is developing a cutting edge offensive weapon for the British military. The mystery unfolds in a setting that includes a nearby German prisoner-of-war camp, as well as an abandoned abbey dating to the Middle Ages, and a turncoat prison camp guard who has lost one arm to the war. In an unexpected display of bravery, the two Scouts foil the German plot and capture the foreign agent, for which they are awarded the King's Scout Award, the highest honor a British Boy Scout can earn.
