The Hunniwell boys and the platinum mystery

The Story

The story begins in the tranquil Maine woods, where Bill and Gordon Hunniwell are fishing on Lost Pond, their lives centered around the rugged, quiet joys of the outdoors. This peaceful routine is shattered by a telephone call from their mother: a man named Rogers, a long-time acquaintance, has arrived with a proposition that promises to pull the boys away from the cabin and into the skies. Rogers, a man who has previously given up aviation, reveals that he has stumbled upon a mystery involving a letter hidden in a trunk, a document that points toward a discovery of potential value in Hawaii. Despite Mr. Hunniwell’s skepticism, the boys and Rogers secure permission to depart. They rely on the "Albatross," a unique, silent electric airplane that the brothers have helped refine, turning their backs on traditional combustion engines for the sake of stealth and efficiency.

Their journey across the United States is a testament to the capabilities of their machine. They navigate the high peaks of the Rockies and eventually reach the Pacific coast at Stockton, where their silent arrival draws the attention of curious, skeptical locals. After a brief rest, they cross the Pacific, encountering a terrifying, disorienting fog that suspends them motionless between sky and water. This experience tests their nerves, forcing them to fly blind until they catch the sound of distant surf. Upon arriving at the island of Oahu, they find themselves in a landscape that defies their expectations of a tropical paradise, characterized instead by harsh, rocky terrain and jagged cliffs.

The central conflict ignites when they discover that their secret cache of battery cells—essential for the Albatross’s operation—has been stolen from its hiding place. They soon realize they are being hunted by a mysterious adversary, a man who appears to have connections to the local landscape and an interest in their plane. The boys and Rogers are forced into a game of cat-and-mouse along the cliffs of Laau Point. During a reconnaissance of a narrow rift in the rock, the antagonist attempts to kill them by dislodging heavy boulders from above. This brush with death forces them to retreat, but the boys’ ingenuity prevails. When Gordon is briefly kidnapped by the man, he manages to manipulate his captor, ultimately orchestrating a daring escape by signaling Bill to bring the Albatross in for a precision landing on uneven ground.

With their enemy temporarily outmaneuvered, the trio returns to their search. They revisit the rift in the cliffs, now armed with a more thorough understanding of the terrain. They realize they had previously overlooked a critical detail: a layer of sand covering the floor of the fissure. After a well-placed explosive charge clears the rubble, they return to find the hidden cache. A series of chemical tests, performed with makeshift equipment and a bit of scientific intuition, confirms their discovery is indeed platinum. The journey concludes with the trio securing the metal and preparing for the flight home, their bond strengthened by the shared danger and the triumph of their shared intellectual and physical labor.

The People

• Bill Hunniwell: The elder brother and a capable pilot, Bill is the pragmatic anchor of the trio. He is responsible for the technical maintenance of the Albatross and is quick to prioritize safety, though he is equally prone to excitement when a challenge presents itself.
• Gordon Hunniwell: Impulsive and clever, Gordon often acts as the catalyst for the group’s risks. He possesses a sharp wit and a natural ability to think on his feet, which proves essential when he is taken captive and must outsmart his adversary.
• Rogers: A mentor figure who brings the boys into the mystery, Rogers provides the initial impetus for the trip. Despite his promise to his wife to give up flying, his desire for discovery pulls him back into the cockpit, where he provides a steady, if occasionally anxious, hand.
• The Antagonist: A mysterious, elusive individual who operates in the shadows of the island. He is motivated by greed and a desire to claim the platinum for himself, showing a willingness to resort to sabotage and violence to remove the Hunniwell boys from his path.

In Its Own Voice

While adjusting to the strange, silent movement of their electric aircraft over the ocean, the boys experience a profound sense of isolation and wonder:

It certainly was a peculiar sensation to be suspended there betwixt sky and water and before long it began to get on their nerves.

When Gordon finds himself held against his will by the man stalking them, he maintains a cool, defiant demeanor that highlights his resourcefulness:

“I’ll find out later,” the Jap said, to which Gordon replied, “Which is on the knees of the gods,” Gordon grinned.

After the dramatic excavation of the cliffside, the tension culminates in a moment of scientific verification that signals the end of their search:

How they all stared as he dropped a small lump into the mixture and how they cheered a moment later as they saw it slowly grow smaller and finally disappear.

What It's Really About

At its core, this story is an exploration of the transition between the mechanical age and the future of science. By centering the plot on an "electric" aircraft that glides in silence, the book frames the Hunniwell boys not just as adventurers, but as innovators. The airplane is not merely a vehicle; it is an extension of their intellect and their friendship. The quiet operation of the plane serves as a metaphor for the boys’ approach to the world: observant, precise, and fundamentally different from the "racket" of the industrialized world that surrounds them.

The book also addresses the tension between the romanticized view of exploration and the harsh reality of the frontier. The boys begin their journey expecting a tropical oasis, only to be confronted by the unforgiving, furnace-like heat and barren rock of the Hawaiian coast. The discovery of the platinum is not a stroke of mere luck, but a result of persistence and the ability to challenge one’s own initial assumptions. When the first attempt at finding the cache fails, it is Gordon’s intellectual humility—his ability to admit he acted like an "idiot" and reconsider the evidence—that leads to the final success. This emphasizes the value of critical thinking over brute force.

Furthermore, the narrative explores the ethics of rivalry. The antagonist is defined by his lack of honor, contrasting sharply with the "word of honor" that Gordon refuses to give when held captive. The conflict is structured not just as a race for wealth, but as a test of character. The platinum, while the nominal prize, serves as a catalyst for the boys to prove their maturity. They navigate the world with a sense of camaraderie that makes them feel invincible, yet they remain grounded by the mundane, ever-present chores of survival—cooking, cleaning, and maintaining their equipment. The book posits that true discovery requires the patience to handle the tedious aspects of life alongside the high-stakes thrills of aviation. Ultimately, it is a story about how young people assert their competence in an adult world, proving that they are capable of navigating "the air" and the earth with equal proficiency.

Why Read It Today

Readers who appreciate a briskly paced, earnest adventure will find much to admire here. The book captures a specific, optimistic 1920s fascination with aviation, where the sky is still a frontier and the idea of a silent, electric plane is a futuristic marvel. It feels like a genuine relic of a time when the "boy’s own" adventure story was the dominant form of escapism.

The reading experience is straightforward and unadorned, characterized by a breezy, conversational tone between the brothers that feels authentic to the genre. However, a modern reader should be prepared for the period’s limitations. The language reflects the racial stereotypes common in the pulp fiction of the 1920s, particularly regarding the antagonist, which may feel jarring or insensitive to contemporary sensibilities. The book does not attempt to be a deep character study; instead, it relies on the momentum of its plot and the mechanical curiosity of its readers.

What stays with you is the sheer sense of possibility that permeates the story. While the mystery itself is solved with the predictability of a classic serial, the image of that silent, electric Albatross cutting through the Pacific haze remains evocative. It is a book for those who want to revisit a time when the world seemed vast, the technology felt revolutionary, and a couple of brothers from Maine could solve a mystery by sheer grit and a bit of scientific luck. It is a light, undemanding, and oddly charming look at how the early 20th century imagined its own future, making it a valuable read for anyone interested in the evolution of juvenile fiction and the history of aviation lore.
