The early days of aviation bring together a pair of resourceful siblings, their mechanical expertise, and a series of high-stakes sky races against unscrupulous industrial rivals.
In Short
This novel follows Peggy and Roy Prescott, siblings who design a superior aeroplane and enter it into a government-sponsored "sky cruise." Along the way, they must contend with the machinations of a wealthy financier, Mr. Mortlake, who seeks to sabotage their machine and ruin their reputation to ensure his own success. Blending elements of early 20th-century aviation wonder with the tropes of a mystery-adventure, the story highlights the siblings' resilience and talent. It remains a notable relic of its era for its early depiction of a female lead who treats flying not as a novelty, but as a serious pursuit.
The Story
The narrative opens in Sandy Beach, where the Prescott siblings are busy finalizing their "Golden Butterfly" aeroplane. Their progress is monitored with intense hostility by Mr. Mortlake and his associate, who view the brother and sister as dangerous interlopers in the lucrative field of government aeronautics. Mortlake’s strategy is simple: if he cannot steal their designs, he will discredit them. He attempts this by framing Roy for meeting with a foreign spy, a plot that lands the boy in a locked cellar. Through quick thinking and a hidden pocket tool kit, Roy escapes just in time to clear his name with the help of a sympathetic naval officer, Lieutenant Bradbury.
The conflict culminates during a grand cross-country aviation contest, the "Sky Cruise." Despite the constant threat of sabotage and a series of unfair hurdles—including attempts to disqualify Peggy based on her gender—the Prescotts remain focused on their goal. They navigate treacherous storms and blinding fogs, relying on their superior engineering and their own steady nerves. When the competition reaches its final stage near Hampton, the rivals' machine, the "Silver Cobweb," falters due to mechanical failure. The Golden Butterfly, piloted by Peggy, finishes with a decisive lead, securing a victory that leaves the critics and skeptics in the crowd silenced.
In the aftermath, the villains are forced to retreat. Mortlake, realizing his schemes have crumbled, eventually moves abroad to start a new, more honest venture, while the Prescott machine is adopted for naval use. The story concludes with a celebratory gathering where the truth about the impersonator who framed Roy is revealed. The siblings look forward to their future in aviation, having proven that their skill is not a matter of luck, but of preparation and integrity.
How It Unfolds
The mystery of the workshop Peggy and Roy observe suspicious activity at a local building where a rival financier is secretly developing his own aircraft. They realize they are being watched, and the rivalry for a government contract begins in earnest.
A test of nerve and skill Peggy takes to the air with Lieutenant Bradbury to navigate a sudden, violent storm. Her success in landing the machine during the gale demonstrates her pilotry and earns the respect of the naval visitor.
The plot thickens Mortlake orchestrates a scheme to frame Roy as a traitor selling secrets to a foreign power. Roy is kidnapped and held captive, forcing him to use his wits and tools to engineer a desperate escape.
The race for glory The competitors gather for the Sky Cruise, a high-stakes event that draws crowds from across the country. Mortlake’s son, Fanning, attempts to provoke a race and cause mechanical damage to the Prescott automobile, further escalating the tension.
Victory in the clouds The race through fog and over difficult terrain puts the machines to the ultimate test. The Golden Butterfly proves its worth, leaving the competition behind and cementing the Prescotts' reputation as top-tier aviators.
The People
Peggy Prescott is the central protagonist, a blonde, determined young woman who possesses both beauty and a sharp, engineering-minded intellect. She wants to prove that women are as capable as men in the cockpit, and she overcomes societal skepticism and active sabotage to achieve this.
Roy Prescott is Peggy’s brother, a capable mechanic and pilot. He is the primary target of Mortlake’s schemes, and his journey involves learning to navigate not just the skies, but also the dangerous social and business world of his rivals. He remains loyal to his sister and their shared ambitions.
Mr. Mortlake serves as the antagonist, a cold, "leathern-faced" financier who believes money and influence can crush any rival. He wants to secure a government contract by any means necessary, but his lack of integrity leads to his ultimate failure and eventual exile.
Lieutenant Bradbury acts as a catalyst and ally. Initially skeptical of the siblings due to Mortlake’s lies, he becomes an advocate for their talent once he witnesses Peggy’s skill in the air. He helps the Prescotts gain the official recognition they deserve.
In Its Own Voice
"It isn't to be a barn; that's one thing certain. Who ever saw a barn with skylights on it?"
Peggy observes the mysterious construction of her rival's workshop at the start of the story.
"I guess this 'old car,' as you call it, could give yours a tussle if it comes down to it."
Roy defends his and Peggy's vehicle against the taunts of their rival, Fanning Harding.
"In years to come," prophesied Peggy, "I dare say women as aviators will be as common as men."
Peggy expresses her forward-looking vision for the future of aviation during a casual conversation.
What It's Really About
At its core, this book is an argument for the democratization of technological advancement. It posits that merit—specifically the superior engineering of the Prescotts—should outweigh the gatekeeping of established, wealthy interests. Beneath the adventure plot, there is a consistent theme of gender equality; the author frequently uses Peggy to challenge the period's assumptions about what is "proper" for a young woman. The story also explores the tension between technological progress and industrial greed, suggesting that true innovation requires a level of honesty and hard work that the antagonist, Mortlake, is ultimately unable to provide. It is a story about the transition into a modern age, where skill and character are the true measures of success.
Why Read It Today
Readers will enjoy this book for its earnest, high-energy tone and its nostalgic look at the "infancy" of flight. Those interested in the history of aviation or early 20th-century juvenile fiction will find the mechanical descriptions and the period-specific optimism for the "new science" of flight particularly engaging. The camaraderie between the siblings and their friends creates a sense of warmth that carries the story through its more dramatic, sometimes improbable, plot twists.
However, modern readers should be prepared for the stylistic conventions of the era. The prose is filled with the slang and moralizing common to its time, and the "villain" characters often behave with a cartoonish malice that may feel dated. Additionally, the dialect used for some of the rural characters reflects period attitudes that are not representative of modern standards. Despite these historical artifacts, the book remains a compelling read for anyone curious about how the archetype of the "girl adventurer" was constructed during the early years of the twentieth century. Peggy Prescott stands out as a character who is allowed to be both physically brave and intellectually sharp, making her an enduring, if classic, example of a pioneering literary heroine.
