Quick confession: I’ve known about Henry Kuttner for years. His name kept popping up in those “forgotten masters of weird fiction” lists, nestled between Lovecraft and Bloch, praised by Ray Bradbury as a “neglected master”. I’d even read a few of his sci-fi stories and enjoyed them well enough. But somehow, I’d never really committed to exploring his horror work. That changed a few months ago when I researched the story “The Graveyard Rats” which was adapted for Guillermo del Toro’s Cabinet of Curiosities. If del Toro gave Kuttner a spot alongside Lovecraft in his curated horror anthology, I figured it was time to stop procrastinating.

What followed was a descent into some of the most visceral, claustrophobic, and genuinely unsettling horror fiction I’ve encountered in years. Kuttner’s work doesn’t have the cosmic philosophizing of Lovecraft or the poetic doom of Clark Ashton Smith. Instead, his horror feels immediate—pulpy and physical, with a relentless forward momentum that grabs you by the throat and doesn’t let go until the final, often devastating sentence.

Over the past few weeks, I’ve become obsessed with four stories in particular: “The Graveyard Rats,” “The Salem Horror,” “I, the Vampire,” and “Hydra.” These tales showcase Kuttner at his absolute best—combining imaginative cosmic horror with gut-wrenching physical terror, all wrapped in prose that’s sharp, economical, and devastatingly effective. Let me take you through each one.
The Graveyard Rats (1936): Buried Alive in Your Own Greed
The Story:
“The Graveyard Rats” was Kuttner’s first published horror story, appearing in Weird Tales in March 1936. It follows Old Masson, the caretaker of a decrepit Salem cemetery who supplements his meager income through grave robbing—stealing jewelry, gold teeth, and anything valuable from the recently deceased. His profitable side business faces an unusual problem: abnormally large rats have infested the graveyard, tunneling through the earth and dragging entire corpses through holes they gnaw in coffins.
These aren’t ordinary rodents. They’re massive creatures, some as large as cats, with origins traced to “strange cargoes” brought generations ago from distant ports to Salem’s rotting wharves. The cemetery caretaker has heard disturbing legends about “moribund, inhuman life” existing in forgotten burrows beneath Salem, tales of ghoulish beings commanding rat armies and stealing bodies for “nocturnal subterranean feasts”.
One rainy night, desperate for money, Masson attempts to rob a freshly buried corpse he knows wore expensive cufflinks and a pearl stickpin. When he opens the coffin, he discovers the rats have beaten him by mere minutes—a shoe disappears into a gnawed hole at the coffin’s end as he watches. Greed overcomes caution, and Masson crawls into the burrow after his stolen prize.
What follows is a masterclass in sustained claustrophobia. Masson squeezes through increasingly narrow tunnels, the “musty stench of carrion” overwhelming as he pursues the dragging corpse deeper underground. When he finally tries to retreat, he discovers the burrow is too narrow to turn around. Panic sets in as the rats attack—great grey monsters with “dull orange teeth” and “long ragged whiskers”. He fires his revolver repeatedly, temporarily driving them back, but glimpses something worse: a dark shape of “unbelievable size” lurking in the shadows.
Then Masson encounters the thing that still gives me nightmares: a crawling mummy, “a brown and shriveled” corpse with “a frightful gargoyle face” and “glazed eyes swollen and bulbous” that betray its blindness. This undead horror groans as it crawls toward him, its “ragged and granulated lips” stretched in “a grin of dreadful hunger”.
In his panic to escape this blind dead thing, Masson desperately tries to collapse the tunnel behind him by dislodging a large stone. He succeeds—but triggers a cave-in that seals his own fate. The tunnel collapses at his heels as he scrambles forward into what he thinks is salvation: an empty coffin that a rat had previously hollowed out. Trapped face-down in this sarcophagus, unable to turn or escape, Masson suffocates in the fetid darkness as the “exultant squealing of the rats” fills his ears.
My Take:
This story is relentless. Kuttner wastes no time establishing Masson as an unsympathetic protagonist—he’s a grave robber, a ghoul in his own right—which makes his fate feel like cosmic justice. But what makes “The Graveyard Rats” transcend simple morality-tale revenge is the sheer physicality of Masson’s ordeal. You feel every scrape of his knees on sharp stones, every desperate gasp in the thinning air, every moment of animal panic as the walls close in.
The image that haunts me most isn’t even the giant rats—it’s that blind, crawling corpse. Kuttner describes it with such specific, grotesque detail: the “glazed eyes swollen and bulbous,” the “granulated lips,” the way it groans and hungers. This isn’t cosmic horror about incomprehensible alien geometries; this is body horror, rot horror, the visceral dread of dead things that won’t stay still.
Now let’s talk about the ending. Masson doesn’t get torn apart by rats or consumed by the blind horror—he dies slowly, trapped in a coffin he crawled into seeking escape, suffocating in the darkness while rats squeal their triumph. It’s a perfect ironic punishment for a grave robber: buried alive in someone else’s coffin, gasping for air as the earth itself becomes his tomb. The adaptation in del Toro’s series captured this brilliantly, adding even more visual grotesquerie with a giant rat queen and an underground temple of bones.
Kuttner was only 21 when he wrote this. Think about that. At an age when most writers are still finding their voice, he crafted what remains one of horror fiction’s most effective exercises in sustained, claustrophobic dread.

The Salem Horror (1937): When Writers’ Block Summons Ancient Evil
The Story:
Published in Weird Tales in May 1937, “The Salem Horror” takes a different approach—less immediate physicality, more slow-building atmospheric dread. The protagonist, Carson, is a writer of “light romances” who rents a decrepit old house in Salem’s “witch district” to find peace and quiet to finish his novel.
The house comes with a history. It once belonged to Abigail Prinn, a witch executed during the Salem trials of 1692. The “diabolical old hag” was known for making sacrifices to “a worm-eaten, crescent-horned image of dubious origin” and boasted of being high priestess to “a fearfully potent god which dwelt deep in the hills”. When they tried to burn her, witnesses whispered that “the flames could not burn her, for her whole body had taken on the peculiar anesthesia of her witch-mark”. No one likes to talk about what really happened, and tenants have a habit of leaving hastily with vague explanations about rats.
Carson dismisses these superstitions—at first. But strange sounds emanate from the cellar, and one night, pursuing a rat, he discovers a hidden room behind the walls: the “Witch Room”. This chamber is decorated with disturbing symbols and contains remnants of Abigail Prinn’s occult practices. Carson finds himself strangely compelled to spend time there, and his writing takes on a darker, more visceral quality. He’s being influenced—his dreams invaded by visions of Prinn and her monstrous deity.
The story’s climax involves Michael Leigh, an occultist friend of Carson’s who recognizes the danger. Through research, Leigh identifies the entity Prinn worshipped: Nyogtha, one of Kuttner’s original contributions to the Cthulhu Mythos. When Abigail Prinn’s shriveled corpse manifests in the Witch Room, arms raised in triumphant invocation, Leigh rushes in with occult weapons—an ankh, a sacred elixir, and the Vach-Viraj incantation. He manages to banish both the witch and her deity back to their nightmare realm, though the story ends with an unsettling suggestion that the horror isn’t entirely gone.
My Take:
“The Salem Horror” feels like Kuttner’s most direct homage to Lovecraft, combining New England Gothic atmosphere with Mythos entities. But where Lovecraft would have dwelt on cosmic insignificance and alien geometries, Kuttner keeps the horror grounded in very human terrors: invasion of the creative mind, loss of agency, and the corruption of one’s own work.
The idea of Carson’s writing being influenced by the malevolent presence—his light romances becoming darker without his conscious control—adds a meta-fictional layer that resonates with anyone who’s ever felt their creative work taking unexpected, possibly unwelcome directions. Is it inspiration or possession? Where does the writer end and the supernatural influence begin?
I’ll admit the ending feels a bit rushed, with Leigh showing up to save the day armed with convenient occult knowledge. This is one weakness of Kuttner’s Lovecraft imitations—Lovecraft earned his cosmic revelations through accumulating dread, while Kuttner sometimes uses occult deus ex machina solutions. Still, the journey there is effectively creepy, and the image of the shriveled witch raising triumphant arms in that hidden chamber has genuine nightmare fuel quality.
What I appreciate most about “The Salem Horror” is how Kuttner weaves historical American Gothic—Salem witch trials, Puritan guilt, colonial violence—into his cosmic horror framework. The story suggests these historical traumas literally haunt the present, that Abigail Prinn’s evil wasn’t extinguished but merely waiting for someone foolish enough to unlock that door. It’s less visceral than “The Graveyard Rats” but more psychologically insidious, a slow corruption rather than immediate terror.
Also, Kuttner created Nyogtha specifically for this story. That’s a hell of a contribution to the Mythos—an entity that’s endured in Lovecraftian fiction for nearly 90 years. Not bad for a 22-year-old’s sophomore horror effort.

I, the Vampire (1937): Hollywood Bloodsuckers (Literally and Figuratively)
The Story:
“I, the Vampire,” published in Weird Tales in February 1937, does something unusual for 1930s vampire fiction: it’s set in contemporary Hollywood during the golden age of cinema, and it’s told from the perspective of Mart Prescott, an assistant director at Summit Pictures.
The story opens at a dull party hosted by ace director Jack Hardy. Mart’s fiancée Jean Hubbard tells him about Hardy’s latest publicity stunt: a mysterious European performer called the Chevalier Pierre Futaine, hired to star in a vampire film called Red Thirst. Futaine arrives with an aura of calculated mystery—nobody can photograph him, few have seen him, and “weird tales” circulate about his past in Paris.
But the mystery deepens into genuine horror when a series of deaths plague Hollywood’s elite. Actress Sandra Colter dies under mysterious circumstances, her body drained of blood. More deaths follow, and Prescott begins to suspect that Futaine isn’t playing a vampire—he is one. The Chevalier seems ageless, impossibly elusive, and always near when tragedy strikes.
The investigation leads Prescott to confront Futaine and ultimately discover the truth. But here’s where Kuttner pulls his twist: the story’s title, “I, the Vampire,” doesn’t refer to Futaine. In the final revelation, we discover that Deming Smathers—a supporting character who’s been helping Prescott investigate—is the actual vampire. The story ends with a tragic revelation about the vampire’s nature and motivations, presenting the creature more sympathetically than was typical for the era.
My Take:
I need to be honest: of these four stories, “I, the Vampire” is the one I struggled with most, partly because I couldn’t locate the full text online and had to piece together the plot from multiple sources. But what I’ve gathered makes it one of Kuttner’s most innovative horror tales for its time.
Setting a vampire story in 1930s Hollywood was genuinely clever. Kuttner taps into anxieties about the film industry itself—the manufactured mystery, the publicity machines, the question of what’s real versus what’s performance. Futaine functions as a red herring, a “mystery man” built up through Universal Pictures-style publicity that mirrors how the studio system created stars. In a world of illusion and performance, how do you identify a real monster?
What makes “I, the Vampire” particularly significant is its early sympathetic treatment of the vampire protagonist. While most vampire fiction of the 1930s and ’40s treated vampires as pure evil—following Stoker’s Dracula model—Kuttner was experimenting with more nuanced, tragic vampire figures a full generation before this became common. The reveal that Smathers, not the obvious suspect Futaine, is the vampire adds a layer of pathos to the tale.
The Hollywood setting also allows Kuttner to comment on the film industry’s vampiric nature metaphorically—the way it drains performers, feeds on beauty and youth, creates artificial personas. There’s a satirical edge here alongside the horror, a self-awareness about genre conventions and publicity that feels surprisingly modern.
My main frustration is that without access to the complete text, I can’t fully appreciate how Kuttner balances these elements. But even from summaries and fragments, “I, the Vampire” emerges as an ambitious, innovative take on vampire fiction that anticipated later genre developments by decades.

Hydra (1939): Astral Projection Gone Catastrophically Wrong
The Story:
“Hydra,” published in Weird Tales in April 1939, is Kuttner’s cosmic horror masterpiece and possibly his most disturbing tale. The story unfolds through a documentary-style narrative, piecing together diary entries and newspaper reports to reconstruct a catastrophe: “Two men died; possibly three”.
The tale centers on three occultists: Kenneth Scott, a Baltimore author with “one of the best occult libraries in America”; Robert Ludwig; and Paul Edmond. Ludwig and Edmond, deeply interested in the occult through their friendship with Scott, discover a privately printed pamphlet called On the Sending Out of the Soul that details a formula for astral projection.
The pamphlet’s first seven pages contain “vague mystic writing,” but the eighth page provides explicit instructions: a brazier, the drug cannabis indica, and a specific ritual formula. What the pamphlet doesn’t mention—what it can’t mention, because no one who successfully performed the ritual survived to warn others—is the catastrophic side effect: the ritual invokes the Hydra, a horrific Outer God that dwells in the same dimension as Azathoth.
Against Scott’s explicit warnings—he sends a desperate telegram: “ATTEMPT NO EXPERIMENTS WITH PAMPHLET YOU MENTION STOP TREMENDOUSLY DANGEROUS AND MAY MEAN MY DEATH”—Ludwig and Edmond perform the ritual. Their astral forms successfully project, and both have an identical vision: they see Kenneth Scott’s crumpled body in his Baltimore study, his head “doubled at an impossible angle out of sight beneath the torso, or else he was headless”.
This vision proves prophetic. Days later, newspapers report Scott’s mysterious murder: he’s been found decapitated, his head missing entirely. The tabloids sensationalize “the mysterious mutilation and death of Kenneth Scott, noted Baltimore author and occultist”.
But the horror doesn’t end there. Ludwig and Edmond’s astral projection opened a doorway—they’ve drawn the attention of something from Outside. The story fragments into diary entries describing increasingly nightmarish experiences. They encounter alien dimensions with geometries that don’t obey earthly physics, populated by grotesque entities. Scott’s consciousness, trapped in the astral plane, begs Ludwig to be freed from “eternal torment”.
The climax reveals the true horror: when you perform the ritual, your astral body doesn’t simply travel—it becomes a conduit. The Hydra uses the connection to enter our dimension, and its presence means death. Paul Edmond dies “ghastly death” separated from Scott’s murder “by the width of a continent,” but clearly connected to the same cosmic horror. Robert Ludwig disappears entirely, his fate unknown. Only fragmentary diary entries remain to tell the tale.
My Take:
“Hydra” is the story that’s kept me up at night. Where “The Graveyard Rats” offers visceral, claustrophobic terror and “The Salem Horror” provides atmospheric dread, “Hydra” delivers existential cosmic horror in its purest, most nightmare-inducing form.
What makes it so effective is the documentary structure. We’re piecing together a catastrophe after the fact, reading diary entries from men who don’t yet realize they’re doomed. There’s a horrible inevitability to it—we know from the opening line that “two men died; possibly three,” and we watch helplessly as Ludwig and Edmond proceed with their experiment despite Scott’s frantic warnings.
The vision they share—Scott’s headless or nearly-headless body—is genuinely disturbing in its ambiguity. The detail that both men see the same thing confirms it’s not hallucination but genuine astral perception, which makes the subsequent discovery of Scott’s actual decapitated corpse all the more horrifying. Their experiment somehow caused or enabled his death across hundreds of miles.
But the real horror lies in what comes after: the suggestion that consciousness can be trapped in dimensions where normal physics don’t apply, where you can be aware and suffering but unable to die or escape. Scott’s spirit begging to be freed from “eternal torment” in the astral plane is one of those images that lodges in your brain and refuses to leave.
Kuttner’s descriptions of alien dimensions—though necessarily vague, given the documentary style—are genuinely imaginative. He’s trying to convey “the Ultimate Chaos” that rests at the universe’s center using fragmentary diary entries and newspaper reports, and somehow it works. The gaps in knowledge, the fragmented narrative, the piecing-together quality—it all reinforces the sense that we’re glimpsing something too vast and terrible for human comprehension.
The Hydra itself is one of Kuttner’s most significant contributions to the Cthulhu Mythos—an entity that may be identical to or closely related to Azathoth, requiring a portal to enter universes other than its own. The idea that this horror lives in a dimension adjacent to ours, waiting for foolish humans to open doorways, taps into primal fears about forbidden knowledge and cosmic indifference.
What I dig most about “Hydra” is how it makes astral projection—usually presented in occult literature as a spiritual practice or magical skill—into a vector for cosmic horror. The story asks: what if sending your consciousness Out There really worked? What if you really could project your spirit beyond your body? And what if the things waiting Out There noticed you?
It’s the horror of getting exactly what you wished for, only to discover it comes with consequences you never imagined. Ludwig and Edmond don’t summon a demon through ignorance or evil intent—they’re curious scholars pursuing esoteric knowledge. Their fate feels desperately unfair, which makes it all the more horrifying. The universe in Kuttner’s “Hydra” doesn’t care about your intentions or your innocence. Open the wrong door, and something might come through. Or worse: you might go Out, and never find your way back.

Madness that Matters
Spending these weeks immersed in Kuttner’s horror fiction has fundamentally changed how I think about the genre’s history. We talk endlessly about Lovecraft (deservedly), occasionally mention Clark Ashton Smith, maybe throw in Robert Bloch if we’re feeling comprehensive. But Kuttner deserves to be mentioned in the same breath with any of them.
What sets him apart is that physicality—the way his horror exists not just in cosmic vistas and alien geometries, but in the immediate, visceral experience of terror. Masson’s claustrophobic crawl through rat tunnels, the blind dead thing’s hungry groaning, Scott’s severed head, the rats swarming from the dead grave robber’s mouth in del Toro’s adaptation—these images have a gut-level impact that purely cosmic horror sometimes lacks.

Kuttner could also do cosmic horror when he wanted to, as “Hydra” and “The Salem Horror” demonstrate. He created lasting additions to the Mythos—Nyogtha, the Hydra, the Book of Iod—that other writers continue to use. He experimented with narrative structure, using documentary frameworks and unreliable perspectives. He brought vampires into Hollywood and made astral projection a vector for existential dread.
And he did all this while supporting other writers. Ray Bradbury said Kuttner wrote the final 300 words of his first horror story when Bradbury was stuck. He corresponded with Lovecraft, receiving detailed critiques that shaped his craft. He collaborated seamlessly with his wife C.L. Moore on numerous stories. By all accounts, he was generous, supportive, and encouraging—the opposite of the isolated, bitter genius mythology that sometimes surrounds horror writers.

His death at 42 from a heart attack was a genuine tragedy for the field. Who knows what he might have written in another 20 or 30 years? What cosmic horrors remained unexplored, what new narrative techniques untried?
But what he left us—stories like these four, plus dozens of others scattered through pulp magazines and later collections—remains vital, disturbing, and absolutely worth seeking out. If you, like me, somehow let Henry Kuttner slip through your reading list for too long, I can’t recommend strongly enough that you correct this grievious oversight.
Start with “The Graveyard Rats.” Let Masson’s desperate, doomed crawl through those rat-infested tunnels pull you into Kuttner’s world of immediate, visceral horror. Then move on to “Hydra” and let the cosmic dread seep in. By the time you finish, you’ll understand why Guillermo del Toro adapted him, why Ray Bradbury called him a neglected master, and why I’ve spent the last few weeks unable to get these grotesque, brilliant stories out of my head.
All four stories are available in various collections, such as the Centipede Press volume Henry Kuttner: Masters of the Weird Tale. “Hydra” and “The Salem Horror” can be found in the recently re-released collection “The Book of Iod“, which showcases Kuttner’s more Lovecraftian tales. “The Graveyard Rats” and “The Salem Horror” are also available free through Project Gutenberg and Wikisource, as they’ve entered the public domain.
