This book is part of a series that follows the exploits of a group of young aviators, focusing on their thrilling missions that often involve espionage and danger. In this installment, the main characters—Ben Whitcomb, Jimmie Stuart, and Carl Nichols—embark on a government-sanctioned mission to rescue an abducted post-office inspector who holds crucial evidence against a fraudulent mail-order company. The opening portion of the narrative introduces the boys as they camp in the Rocky Mountains, having just arrived from a prior adventure in Peru. As they enjoy a meal prepared over a campfire, they encounter an unexpected grizzly bear that comes tumbling down a slope, raising suspicions about danger nearby. This leads them to a confrontation with two suspicious men who pose as government officials but whom the boys doubt. As the story unfolds, tensions rise as the boys are drawn into a web of intrigue involving missing documents, potential danger from the men in the camp, and the threat to their own safety. The stage is set for an exciting adventure filled with high-flying thrills and mystery. (This is an automatically generated summary.) Reading ease score: 82.2 (6th grade).
