The movie boys in peril

In Short

This book follows two teenage cinematographers, Blake and Joe, as they travel to the Panama Canal to capture footage of the massive engineering project. Their professional assignment takes a dark turn when they become suspicious of their traveling companion, a man named Mr. Alcando. As the boys navigate tropical jungles and industrial work sites, they uncover a plot to sabotage the canal’s infrastructure. It is a quintessential example of early 20th-century juvenile adventure fiction, emphasizing ingenuity, technical skill, and the patriotic duty of young men to protect national interests.

The Story

Blake and Joe are vacationing in the countryside when they intervene in a dramatic carriage runaway, saving the life of a mysterious South American man named Mr. Alcando. This encounter leads to an unexpected career opportunity: Mr. Alcando, claiming to be an inventor, encourages the boys to accept a film assignment at the newly constructed Panama Canal. Lured by the chance to document such a historic feat of engineering, the boys agree.

Once in Panama, the boys begin filming the massive locks and the Culebra Cut. However, their experiences are marred by unsettling occurrences. They notice Mr. Alcando acting suspiciously, often muttering to himself and handling a strange, ticking brass box. When a government tugboat is involved in a suspicious collision within the canal locks, the boys begin to suspect that their companion is not who he claims to be. Their intuition is confirmed when they overhear him talking about using dynamite to damage the dam, citing the vulnerability of the canal to its enemies.

The tension peaks when rumors of an imminent attack on the Gatun Dam spread through the Canal Zone. A local official, aware of the boys' presence and their cameras, enlists their help to document a potential sabotage attempt. Armed with their cameras and a plan to use a powerful flashlight to capture the culprits in the act, Blake and Joe set up an ambush near the dam.

On the night of the planned attack, the boys encounter Mr. Alcando in a restricted area. Using their pliers to sever the wires leading from his "infernal machine"—the brass box—they render his device harmless just as the flash goes off. Captured by guards, Alcando confesses that he intended to stage a minor explosion to create the appearance of a disaster, hoping to benefit from the resulting confusion or political fallout. The book concludes with the boys vindicated in their suspicions and successful in their mission to secure the canal’s safety, though the revelation of the man’s true, albeit half-hearted, motives leaves them reflecting on the strange nature of the conspiracy they have unraveled.

How It Unfolds

The chance meeting Blake and Joe prevent a fatal carriage accident, forming an unexpected bond with the mysterious Mr. Alcando. This encounter serves as the catalyst for the boys' invitation to travel to the Panama Canal for a lucrative film project.

The arrival in Panama The boys settle into the Canal Zone, beginning their work as professional cinematographers while documenting the massive locks. The environment is awe-inspiring, but the boys soon find themselves unsettled by the strange behavior of their Spanish companion.

The growing suspicion A series of accidents and odd occurrences on the canal lead the boys to doubt Mr. Alcando’s stated intentions. Their unease intensifies when they discover his secret, ticking apparatus and hear him discussing the use of explosives to damage the dam.

The trap is set When authorities learn of a planned attack on the Gatun Dam, they recruit the boys to use their technical equipment to record the saboteurs. Blake and Joe prepare for a nighttime stakeout, positioning their cameras to catch the perpetrator in the act.

The final confrontation The boys successfully disable Mr. Alcando’s bomb just as he attempts to trigger it. The subsequent capture of the Spaniard confirms his role as a saboteur, leading to a confession that reveals his bizarre motivation for staging a fake catastrophe.

The People

Blake is the leader of the duo, possessing a steady hand and a quick, logical mind. He is the one who handles the technical challenges of the camera and maintains his composure when physical danger arises. He drives the investigation, constantly weighing facts against his growing distrust of their companion.

Joe is Blake’s loyal friend and partner, equally brave but perhaps more prone to sudden worry. He serves as the primary foil to Blake, often verbalizing the fears that Blake keeps to himself. Through their teamwork, Joe’s observations and Blake’s decisive actions form a complete investigative front.

Mr. Alcando is the enigmatic antagonist. He presents himself as a cultured, somewhat naive inventor, but his true identity remains masked by a facade of politeness and charm. Driven by a vague desire to prove a point or benefit from chaos, his actions are erratic; he is not a professional criminal, but an amateur conspirator whose internal conflict occasionally leaks into his speech. His eventual capture results in a confession that reveals him to be more of a misguided figure than a hardened villain.

In Its Own Voice

“I should say not!” answered the one who had ridden in front, and guided the steed of steel and gasoline.

Blake asserts his technical control over the powerful motorcycle during the initial chase scene.

“Yes, it was I who tried to blow up the dam,” Alcando admitted, “but, as you have seen, it was only to be an attempt to damage it.”

The antagonist confesses his motive after being caught red-handed by the boys' camera equipment.

What It's Really About

At its heart, the book explores the tension between human ingenuity and the vulnerability of the modern technological landscape. The Panama Canal serves not just as a backdrop, but as a symbol of American progress and power that requires constant vigilance to maintain. The story argues that the tools of the future—in this case, the moving picture camera—are essential instruments for truth-seeking and security. It asks the reader to consider the dangers posed by those who would subvert great works for personal or political motives. Ultimately, it validates the idea that skepticism is a necessary trait, and that a sharp, observational eye is the most effective defense against those who would exploit the trust of a nation.

Why Read It Today

Readers who enjoy historical snapshots of industrial progress will find the descriptions of early 20th-century camera technology and the construction of the Panama Canal fascinating. The book captures a specific, energetic tone—the "hustle" of early American cinema—where every problem is solved with a mix of mechanical skill and daring. The prose is straightforward and punchy, reflecting the rapid-fire style of serial fiction from the 1920s.

However, the modern reader should be prepared for the narrative conventions of the era. The characters are defined by their clear-cut roles, and the story relies heavily on the "suspicious foreigner" trope prevalent in its time. The dialogue can feel didactic, and the pacing is dictated by the episodic nature of the series, with frequent references to the characters' past adventures. Despite these period attitudes, there is a genuine warmth in the friendship between Blake and Joe that remains relatable. If you appreciate the "gee-whiz" spirit of early juvenile fiction and are interested in the transition from the frontier spirit to the industrial age, this provides a clear, brisk window into that world. It is a time capsule of a period when the world felt both larger and more easily conquered by a couple of boys with a camera.
