Prometheus Graft: The Slayings at Death’s End #1 Introduces Oni Press’ Monstrous New Detective
A monster becomes the detective.
Prometheus Graft: The Slayings at Death’s End #1 launches this December from Oni Press, introducing a gothic murder mystery where the creature once known as Frankenstein’s Monster has reinvented himself as the world’s greatest criminal investigator.
Written by George Northy with art by Caitlin Yarsky, the four-issue series blends classic detective fiction, dark fantasy, supernatural horror, and monster mythology into a new kind of whodunnit. The debut issue arrives on December 9, 2026, and sends readers to a remote Romanian castle where one murder could ignite a paranormal war.
For readers who love gothic mysteries, classic monsters, and supernatural detective stories, Prometheus Graft looks like one of Oni Press’ most intriguing new launches of the year.
Once Mankind’s Greatest Monster, Now the World’s Greatest Detective
The hook is instantly strong.
Decades after his creation, the creature once known as Frankenstein’s Monster has escaped the shadow of his origin. His scars have faded. His hulking nature has been tempered by a genius-level intellect. Instead of remaining a monster of fear and tragedy, he has become Prometheus Graft, a gentleman detective and expert investigator with a mind built for impossible mysteries.
That twist gives the series a sharp identity. This is not just another Frankenstein retelling. It asks what happens when one of literature’s most famous creations becomes the person called in to solve supernatural crimes.
Murder at Death’s End Castle
The first case takes Graft to the remote Romanian castle of Death’s End, where an immortal lord has gathered Europe’s most feared supernatural beings to renew a fragile peace.
Vampires, witches, werewolves, ghouls, and other night-born powers are all under one roof. The goal is diplomacy. The result is murder.
When a prominent guest is found dead in the castle’s hedge maze, the treaty begins to collapse. Suspicion spreads quickly. Witch turns against werewolf. Vampire turns against ghoul. Every faction has a motive, and every monster has something to hide.
That makes The Slayings at Death’s End feel like a classic locked-room mystery filtered through gothic horror.
George Northy Builds a Monster-Mash Whodunnit
Writer George Northy describes the series as an Agatha Christie-style mystery with a supernatural twist. Instead of casting a traditional detective in the lead role, Northy looked to Mary Shelley’s creature: brilliant, tortured, and already a living puzzle.
That idea becomes the foundation of Prometheus Graft. He is not only solving the mystery at Death’s End Castle. He is also trying to understand himself — what he is, who made him, and what his grafted-together existence truly means.
That gives the story two mysteries at once. There is the murder in the castle, and there is the detective’s own unresolved identity.
Caitlin Yarsky Brings Gothic Horror to Life
Artist Caitlin Yarsky brings the world of Prometheus Graft to life with a strong gothic visual identity.
The covers show an elegant but dangerous world filled with castles, occult symbols, monstrous silhouettes, and detective-noir atmosphere. Graft himself looks refined and haunted, carrying the presence of a man who has rebuilt himself from tragedy but can never fully escape what he was.
Yarsky described the project as a playground for supernatural storytelling, blending classic murder mystery, dark fantasy, and gothic horror. That combination is exactly what makes the book stand out.

A Supernatural Peace Treaty Turns Into a Bloodbath
The murder mystery setup gives Prometheus Graft: The Slayings at Death’s End #1 strong story momentum.
The castle is supposed to host a treaty renewal between clans of vampyrs, witches, and werewolves. Instead, it becomes a crime scene. That means Graft is not only solving a murder. He is trying to prevent an all-out paranormal war before dawn.
That raises the stakes immediately. If Graft fails, the consequences will not stay inside the castle walls. The fragile balance between supernatural factions could collapse, bringing bloodshed far beyond Death’s End.
Cover Lineup
Prometheus Graft: The Slayings at Death’s End #1 arrives with a strong cover lineup from Oni Press.
Cover A: Caitlin Yarsky
Cover B: Eric Powell
Cover C: Gabriel Rodriguez
Cover D: Blank Sketch
Variant Cover 1:20: Patricia Martín
Full Art Cover 1:50: Eric Powell
The main cover by Caitlin Yarsky introduces Graft and the larger mystery with a clean, character-driven composition. Eric Powell’s cover leans harder into gothic monster energy, while Gabriel Rodriguez brings a classic horror-adventure mood. The blank sketch cover gives collectors and convention fans an option for commissions, while the incentive variants add more chase appeal.
Why Prometheus Graft #1 Should Be on Your Pull List
This debut has a clean and highly marketable concept: Frankenstein’s creation becomes a supernatural detective.
That alone gives the book strong crossover appeal for fans of classic monsters, gothic horror, murder mysteries, and occult fantasy. But the series also has enough character depth to feel like more than a gimmick. Graft is not simply a monster wearing a detective coat. He is a creature trying to solve the mystery of others while still living inside the mystery of himself.
The result looks like a smart mix of Sherlock Holmes, Agatha Christie, Frankenstein, and monster-war horror.
