Tarzan the invincible

In Short

This high-stakes adventure follows a group of political extremists who venture into the African interior to loot the lost city of Opar and incite widespread rebellion. Their path inevitably crosses with Tarzan, whose home and domain they threaten to exploit. As the expedition collapses under the weight of betrayal, greed, and internal cowardice, the ape-man moves with lethal precision to dismantle their plans. A signature work of the genre, the book remains a definitive example of early twentieth-century pulp fiction, celebrated for its relentless pacing and vivid, exotic world-building.

The Story

The narrative begins with a diverse band of agitators, led by the volatile Peter Zveri, embarking on an expedition under the guise of scientific inquiry. Their true goal is to reach Opar, a legendary, crumbling city of gold that serves as a remnant of a lost Atlantean civilization. Among the travelers is Zora Drinov, a woman whose beauty and intelligence set her apart from her comrades, and Wayne Colt, an American whose presence in the camp remains shrouded in mystery. As they journey deeper into the jungle, they are stalked by Tarzan, who watches from the canopy, initially indifferent to their squabbles but keenly aware that their presence represents a danger to his territory.

The expedition’s progress is marred by the shifting loyalties of their hired warriors and the rising tensions among the white conspirators. Upon reaching the outskirts of Opar, the party is gripped by superstition and fear, leading to a disorganized and bloody attempt to breach the city’s ancient walls. During the chaos, Colt is captured by the grotesque, savage priests of Opar, while Zora and the others are scattered. Tarzan, meanwhile, finds himself drawn into the city’s heart, where he encounters La, the high priestess of Opar, who has been imprisoned by her own people. In a twist of fate, Tarzan and La manage to survive the perils of the ruins, aided by the unexpected intervention of Jad-bal-ja, the golden lion, whose memory of past kindnesses compels him to protect the priestess.

As the conspirators retreat, their expedition falls into total disarray. Zveri’s leadership crumbles, and the internal hatreds between his followers—particularly between the cynical Romero and the ego-driven Zveri—threaten to destroy them all. Zora, having escaped her captors, eventually reunites with a wounded Wayne Colt. Through a series of desperate encounters, the remaining members of the party are forced to confront their own moral failings and the brutal reality of the wilderness. Tarzan, having recovered from his injuries, orchestrates the final act. He tracks the remnants of the group, not as a mere predator, but as a force of nature restoring order. He spares the lives of those who show potential for redemption, including Zora and Colt, while ensuring that the threat of the expedition is permanently neutralized. The story concludes with the survivors reflecting on the gulf between their civilized ambitions and the raw, instinctual wisdom of the ape-man, as Zora and Colt find a future together, far removed from the political machinations that brought them to the jungle.

How It Unfolds

The expedition gathers. A group of revolutionaries and their hired porters set out for the ruins of Opar, motivated by a mix of political zeal and simple greed. They believe the gold of the ancient city will fund their dreams of global upheaval.

The jungle watches. Tarzan begins his surveillance from the trees, observing the group’s internal friction and the suspicious death of one of their own. He remains detached, waiting for the right moment to intervene and protect his domain from these outsiders.

The assault on Opar. The conspirators arrive at the city, where their confidence shatters against the reality of the ancient, terrifying inhabitants. The ensuing panic causes the party to fracture, leading to the capture of Wayne Colt and the temporary loss of La.

Survival and reconnection. Zora Drinov and Wayne Colt navigate the dangers of the jungle separately, finding unexpected help from the animal kingdom and their own resilience. Their paths converge as they confront the remnants of their former allies.

The final reckoning. Tarzan descends upon the disorganized camp, effectively ending the threat of the conspiracy. He exercises his authority to judge the intruders, exiling those he deems unworthy and allowing the others to depart, forever changed by their experience.

The People

Tarzan serves as the untouchable arbiter of the jungle, driven by a protective instinct that encompasses both his animal companions and the land itself. He does not seek conflict, but he responds with absolute finality to those who threaten the natural order.

Zora Drinov is a complex figure, an agitator whose intellect and poise stand in stark contrast to the coarseness of her male peers. She is the moral anchor for Wayne Colt, an American whose path is defined by his growing disillusionment with the group’s radical cause and his deepening bond with Zora.

Peter Zveri acts as the foil to these characters; he is a man of limited courage and boundless ambition, whose arrogance makes him an ineffective leader. His constant clashes with Miguel Romero, a man who harbors a hidden code of honor, highlight the fatal flaw of the expedition: their inability to trust one another. Together, these figures illustrate the fragility of human ideologies when faced with the unforgiving reality of the wild.

In Its Own Voice

"I am Wayne Colt," he replied, "and I take it from the fact that you guessed my identity that this is Comrade Zveri's camp."

(Wayne Colt introduces himself to Zora Drinov upon finding her in the conspirators' camp.)

"There is no God," she reminded him.

(Zora Drinov challenges Colt’s religious leanings during a conversation about their shared mission.)

"The whites are mine!" it cried. "Leave them to me."

(Tarzan issues a command from the trees that strikes terror into the hearts of the mutinous warriors.)

What It's Really About

At its core, the book examines the friction between the hollow structures of human civilization and the enduring strength of natural instinct. The "scientific" expedition is merely a facade for a greed-driven political agenda, one that the author portrays as inherently corrupt and self-destructive. Through the contrast between the treacherous "civilized" men and the noble, protective behavior of the animals—like the golden lion Jad-bal-ja—the narrative argues that human social constructs often suppress the very qualities of loyalty and courage that are essential for survival. The lost city of Opar acts as a haunting reminder of the impermanence of even the most powerful empires, suggesting that no amount of gold can protect a society from its own internal rot.

Why Read It Today

Readers who enjoy the brisk, cinematic pace of early twentieth-century adventure will find much to admire here. The narrative style feels remarkably modern in its "cutting" between parallel storylines, a technique that maintains high tension throughout. It offers a vivid, if idealized, vision of an untamed Africa that serves more as a mythological backdrop than a historical one.

Modern readers should be prepared for the period-specific attitudes regarding race and gender, which reflect the sensibilities of 1930s pulp literature. The characters often fall into archetypes—the stoic hero, the beautiful but inscrutable woman, and the villainous agitator—which can feel predictable by contemporary standards. However, the book’s enduring appeal lies in its commitment to pure escapism and its refusal to dwell on moral ambiguity for long. It is a story about the triumph of the individual over the collective, and for those who enjoy being transported to a world where a whisper in the trees can silence an army, the experience remains uniquely satisfying. It captures a specific, bygone atmosphere of "lost world" fantasy that is both nostalgic and thoroughly engrossing.
