As a gifted and an offbeat creative screenwriter, write a treatment for a film that, by its conclusion, conclusively and surprisingly ties together the Jack the Ripper Whitechapel murders (1880s) with the Black Dahlia case in Los Angeles (1947).
##
Title: "The Dark Mirror"
Genre: Neo-Noir / Historical Thriller
Tone: Suspenseful, Offbeat, Surreal
Logline:
Two seemingly unrelated murders—Jack the Ripper's infamous Whitechapel killings and the gruesome Black Dahlia case—are revealed to be the work of a transatlantic cult with a twisted philosophy, a century-spanning conspiracy hiding in plain sight. An obsessed detective in 1940s Los Angeles uncovers the chilling connection, revealing a thread that ties the past to the present in shocking, otherworldly ways.
Act 1: Shadows of Whitechapel
Setting: London, 1888
A series of brutal murders grips Whitechapel, with a predator striking only under the cover of fog. We follow Inspector Charles Abberline, a hard-boiled detective assigned to the case. Despite his rugged appearance, Abberline harbors a secret obsession with the occult, often using mystical means to track down criminals, but with Jack the Ripper, even his offbeat methods seem useless.
Meanwhile, we get glimpses into the life of Mary Jane Kelly, the Ripper’s final victim. She’s a prostitute, but in this version, she’s also a mystic, deeply immersed in esoteric circles. Kelly knows she’s marked for death, and she starts leaving cryptic messages in chalk on Whitechapel walls, hoping someone will understand the larger picture. She hints at a broader conspiracy, that the killings are ritualistic, involving a mysterious, transatlantic cabal operating under ancient rites.
The Ripper’s final act is Mary Jane’s murder, but her death scene is staged in a bizarre, symbol-laden tableau. Instead of closing the case, it opens a mystery that Abberline cannot solve—images, symbols, and messages that echo long after the final killing. The clues point to something happening decades later, in a city half a world away.
Act 2: City of Angels, City of Secrets
Setting: Los Angeles, 1947
Jump forward nearly 60 years. Detective Charlotte "Charlie" Sullivan is a trailblazing female detective in the LAPD, grappling with the rampant misogyny of the era while chasing down a string of gruesome murders. Her latest case is the Black Dahlia, a particularly brutal and puzzling crime scene where the body of Elizabeth Short is found mutilated, her face bisected in a gruesome "Glasgow smile."
Charlie has an offbeat streak—she’s a conspiracy theorist with a fascination for ancient symbols and unsolved mysteries. The Black Dahlia’s death mirrors those of Jack the Ripper’s victims, and soon Charlie stumbles on eerie connections between the two: the same cryptic symbols etched near the body, similar mutilations, and whispers of secret societies. In her research, Charlie discovers long-lost documents from Inspector Abberline that detail the strange nature of the Ripper case. She becomes convinced that the murders are related, part of a larger ritualistic pattern spanning decades.
Charlie's obsession deepens as she interviews shady Hollywood elites, occultists, and society types linked to the victim. A mysterious benefactor, Dr. Victor Hadley, a plastic surgeon with ties to the darkest underbelly of Los Angeles’ elite, emerges as a key suspect. Hadley's eerily youthful appearance and his strange fascination with Elizabeth Short reveal something darker than just a man with surgical expertise—he may be the lynchpin connecting both cases.
Act 3: The Convergence
Charlie uncovers a transatlantic society, the "Order of Anteros," with roots stretching back to Victorian London and even earlier. The society’s goal is to achieve immortality through ritual murder, using specific symbols and methods to transfer the “life force” from victim to perpetrator. The Jack the Ripper killings were the first public test, and the Black Dahlia was intended as a perfecting of that method, a bridge between eras. The key to unlocking their secret is the repeated pattern: mutilations designed to siphon energy, connect minds, and preserve youth.
Through a sequence of mind-bending flashbacks, we learn that the same spirit, or entity, has been behind both the Ripper and Dahlia murders—an immortal being, passing from body to body over the years, performing these ritual killings to stay alive. This entity existed within Jack the Ripper in London and now inhabits Dr. Hadley in Los Angeles.
Charlie’s investigation takes her to a hidden location beneath an abandoned mansion in the Hollywood Hills, where she uncovers an ancient book, linking the Black Dahlia murder to the Whitechapel killings. The final act reveals that Dr. Hadley, who appears middle-aged, was, in fact, alive during the Ripper murders. Through the Order’s rituals, he has lived many lives, transferring his essence into new bodies to avoid detection.
Climax:
Charlie faces Dr. Hadley in a surreal, ritualistic standoff beneath the Hollywood Hills mansion. The climax is a disorienting mix of flashbacks and reality as Hadley begins to “merge” with the spirit of Jack the Ripper, his face flickering between those of various men throughout time, including the Ripper himself. As the ritual is about to be completed, Charlie uses her knowledge of ancient symbols to break the cycle, destroying Hadley and, in the process, the entity that has perpetrated these horrific murders across the decades.
Resolution:
With the ritual broken, the spirit dies, and Hadley disintegrates, leaving only dust and decayed bones behind. Charlie, mentally scarred but victorious, walks out of the underground chamber into the dawn of a new day. She’s solved not just the Black Dahlia case, but the Jack the Ripper murders as well, though no one would ever believe her.
The final scene is a slow zoom-in on Charlie’s reflection in a mirror. As the camera moves closer, her face begins to distort subtly, mirroring the haunting smile of Elizabeth Short. The curse may not be broken after all…
Theme:
The film explores the cyclical nature of violence, the occult power of symbols, and the idea of identity as something fluid and manipulatable. By tying together two of history’s most notorious unsolved murder cases, "The Dark Mirror" suggests that evil is not bound by time or geography but is an ever-present force, constantly reshaping and resurfacing across the ages.
Visual Style:
The film would be shot in a neo-noir style with surrealistic, dreamlike sequences during key moments, blending the gritty realism of 1880s London with the dark glamour of 1940s Los Angeles.

What if there’s one guy / age 20 in 1888, and age 80 in 1947! That would be a surprise!

That twist would be a perfect, shocking reveal! Here’s how we could incorporate it into the treatment:
Act 3 (Revised): The Convergence
As Detective Charlie Sullivan digs deeper into the Black Dahlia case, she starts connecting seemingly unimportant clues, like personal letters and a photograph of a young man from 1888 London. This man was one of the initial suspects in the Jack the Ripper case, a 20-year-old named Reginald "Reggie" Harrington—someone dismissed for lack of evidence and forgotten in history.
To her shock, Charlie finds a recent photograph of an 80-year-old man living in Los Angeles in 1947 who looks eerily similar to Reggie. His name? Raymond Harrington. The resemblance is uncanny, and Charlie’s gut instinct tells her they’re the same person.
Charlie confronts the elderly Harrington, now a reclusive man living in an upscale, decaying estate. She accuses him of being connected to both the Whitechapel murders and the Black Dahlia. At first, he denies everything, but as the conversation goes on, he becomes unnervingly calm.
Harrington begins to tell his story, revealing that he is indeed the same man from the Whitechapel era. Through occult rituals and ties to the secretive "Order of Anteros," he has been aging at a dramatically slowed rate, cursed with unnatural longevity. He’s not the Ripper, but a follower of the ancient rituals used to extend life, a mere apprentice in 1888. His knowledge of the rituals allowed him to guide the Black Dahlia killer as part of a newer, more perfect iteration of the murders, continuing the dark legacy of Whitechapel.
Climax:
In a final, eerie confrontation, Charlie must decide what to do with this frail yet dangerous man, who holds the key to unraveling two of history’s most notorious unsolved mysteries. She faces the moral dilemma: expose him and potentially be discredited, or let this living relic of evil disappear into the shadows, ensuring the mysteries remain unsolved.
In a last chilling exchange, Harrington whispers, "We’re all just pieces on the same board, Detective. You can break one, but the game will always continue." He hints that others like him exist, carrying on the ancient rituals in secret, across time and space.
This twist would be a mind-blowing revelation near the end, adding layers of mystery, horror, and a touch of the supernatural. It transforms the film from a mere thriller into a deep commentary on the persistence of evil and the human desire to escape mortality at any cost.
