Skull-face

In Short

This fast-paced thriller follows Stephen Costigan, an ex-soldier and hashish addict who finds himself ensnared by Kathulos, a mysterious figure operating out of a London opium den. As Costigan acts as an unwilling agent for his master’s global criminal syndicate, he uncovers a plot to overthrow modern civilization using an ancient, supernatural power. Blending early twentieth-century pulp action with cosmic dread, the narrative is an urgent, feverish exploration of survival, moral redemption, and the terrifying realization that humanity is not the only species vying for control of the earth.

The Story

The story begins within the disorienting, hallucinatory haze of a hashish dream, where Stephen Costigan is contacted by a terrifying entity—a yellow, skull-faced apparition. Soon after, Costigan finds himself in a bizarre, smoke-filled opium house in London’s Limehouse district. He meets his master, Kathulos, a cryptic figure who offers the addict the return of his strength and sobriety in exchange for absolute obedience. Costigan, feeling a strange gratitude and captivated by a mysterious woman named Zuleika, unwittingly becomes a pawn in a vast conspiracy.

Costigan’s tasks take him across London, requiring him to impersonate government officials and carry out violent acts of sabotage. He soon learns that Kathulos is not merely an opium lord but an ancient, malevolent being—a survivor from the sunken continent of Atlantis—who intends to use stolen state secrets and armaments to incite a global uprising of colonized races against white supremacy. As Costigan navigates this web of intrigue, he struggles with the dual nature of the elixirs provided by Kathulos: they grant him superhuman strength but also threaten his sanity and life.

A turning point arrives when Costigan meets Gordon, a government agent investigating the same underworld network. Together, they unravel the scope of Kathulos’s plan, realizing that the "master" is an immortal sorcerer who has spent centuries in a state of suspended animation, awaiting the right moment to reclaim his empire. The tension peaks as Costigan, fueled by a final, potent dose of elixir, infiltrates the villain's lair. He engages in a brutal struggle against the Master’s henchmen on the rooftops of London. Ultimately, as Gordon’s forces close in, the headquarters is destroyed by a massive, earth-shaking explosion. Kathulos is presumed dead in the subterranean wreckage. The story concludes with Costigan, finally free from his addiction and his master, looking toward a future of hope with Zuleika, though he and Gordon remain haunted by the knowledge that other ancient, dormant horrors may still lie hidden in the ocean depths, waiting for the day they might emerge to challenge humanity again.

How It Unfolds

The vision in the mist The narrator falls into a deep hashish dream where he encounters a skull-faced entity that promises him a return to manhood. Upon waking in an opulent, smoke-filled lair, he discovers he is bound to this mysterious master by a strange blue scorpion symbol etched onto his hand.

The pawn in play Costigan is tasked with studying the files of a government official named Major Morley to assume his identity. He finds himself caught between his duty to the master and his budding love for a captive girl, Zuleika, who warns him of the danger he is in.

The descent into action Guided by the master’s inhuman commands, Costigan performs tasks that require him to risk his life, including an infiltration of a private estate. As he performs these deeds, he realizes that the elixirs he consumes are burning his life force away, leaving him a hollow shell.

The alliance of the desperate Costigan encounters Agent Gordon, and they share information that reveals the sheer scale of the threat. They deduce that Kathulos is an ancient, supernatural force planning to weaponize global unrest to topple modern governments.

The final confrontation In a climactic battle, Costigan fights his way through the master’s agents on a rooftop while the forces of law and order surround the facility. The narrative concludes with a cataclysmic explosion that buries the villain and his secrets beneath the earth.

The People

• Stephen Costigan: A battle-scarred, drug-addicted man who undergoes a harrowing journey toward redemption. He starts as a broken tool of a sorcerer but gains the strength to fight for his humanity and his love for Zuleika.
• Kathulos: The titular "Skull-face," an immortal sorcerer from Atlantis. He is a master of alchemy and psychological control, fueled by a desire to return to his ancient glory. He views all modern men as expendable primitives.
• Gordon: A sharp, steel-nerved government agent who serves as the voice of reason and reality. He provides the logistical support and scientific perspective needed to understand the scope of the supernatural threat they face.
• Zuleika: A mysterious and beautiful captive within the opium house. She acts as a secret ally to Costigan, risking her life to assist him and providing the moral anchor that keeps him from total despair.

In Its Own Voice

"I thought at first it was merely a skull; then I saw that it was a hideous yellow instead of white, and was endowed with some horrid form of life."

Costigan describes the initial, terrifying appearance of Kathulos as he first intrudes upon his hashish-induced vision.

"The white men's secrets of war will be his. When it comes, I look for a simultaneous uprising against white supremacy, of all the colored races."

Gordon explains the geopolitical scope of the villain’s plan to orchestrate a global, violent revolution.

"I have him to thank for two things—the regaining of my lost manhood—and Zuleika."

Costigan reflects on the paradoxical nature of his servitude, acknowledging that his trauma led him to his only source of true happiness.

What It's Really About

At its core, this narrative is a meditation on the fragility of civilization and the cyclical nature of power. It suggests that history is a thin veneer covering deeper, darker epochs that are never truly gone, only sleeping. The struggle against Kathulos functions as a fight for agency against an all-consuming, prehistoric will. Beyond the plot, the book poses a persistent question: if the world is built upon the ruins of forgotten empires, what happens when those ruins wake up to reclaim their throne? It serves as a stark warning about the hubris of modern progress, which may be entirely unprepared for the return of ancient, alien instincts.

Why Read It Today

Readers who enjoy the fever-dream intensity of early 20th-century pulp fiction will find a unique experience here. It is a fast, relentless read that moves with the logic of a nightmare, perfectly capturing the feeling of helplessness that comes with addiction and the desperate, adrenaline-fueled urge for self-preservation. Those interested in the historical evolution of dark fantasy and "weird fiction" will appreciate how the author weaves ancient occultism into the gritty, industrial setting of post-war London.

However, a reader should be prepared for the period-specific attitudes and the sometimes jarring racial essentialism common to the literature of the 1920s. The prose is often breathless and sometimes overly dramatic, reflecting the high-stakes, sensational style of its original magazine publication. If you can move past these dated sensibilities, you will find a story that remains genuinely unnerving. It stays with you not because of its polish, but because of its raw, visceral conviction—the sense that the narrator is not just telling a story, but is genuinely terrified by the abyss he has peered into. It is a bracing, uncomfortable reminder that beneath the surface of the modern world, the author believes something much older and hungrier is always watching.
