Cronus of the D. F. C

In Short

Set in a future where crime prevention relies on experimental technology, this classic science fiction novella follows detective Jim Forsdon as he joins the newly formed Department of Future Crime. Equipped with "Cronus"—a volatile machine capable of projecting hazy glimpses of upcoming events—the unit witnesses the imminent murder of a young woman named Stella Emerson. As Jim falls in love with Stella while investigating the lead, he races against time to identify her monstrous assailant. The story captures the golden-age thrill of futuristic police procedural work, exploring whether destiny is immutable or subject to human will.

The Story

Detective Jim Forsdon arrives at police headquarters to take on a strange new assignment in the basement office of the Department of Future Crime. Directed by the dogged Captain Marks and maintained by the gentle, eccentric Dr. Howard F. Walker, the department centers around "Cronus," a complex machine of dials, wires, and a massive screen that captures random glances into the future. Though the machine has helped police apprehend robbers immediately after their crimes, Captain Marks harbors a deep skepticism: he believes the future is set and that Cronus only shows what must inevitably happen.

The team’s ultimate test comes when Cronus displays a terrifying scene of a shadowy, towering man creeping up on a woman in a living room and stabbing her. Working from minute details in the projection—a door scanner, a specific sofa, and a heavy-set assailant with a pronounced limp who uses his left hand—Forsdon scours New York City. He successfully locates the apartment of Stella Emerson, a quiet, striking woman who once worked for the Civil Service on Mars.

Upon meeting Stella, Jim falls deeply in love with her serene nature and charmingly retro sensibilities. Stella recognizes the description of the giant assailant as Mike Gregory, a lonely, pathetic handyman she had known on Mars who had attempted to court her. Realizing Gregory has returned to Earth, Jim acts swiftly to protect Stella, moving her out of her apartment to her aunt's house in Newark and placing a strict police guard on her home.

Despite Jim's elaborate precautions, the timeline marches inexorably forward. Gregory evades a massive police dragnet, escapes custody after being briefly detained, and sneaks into Stella's apartment building by scaling the outer ledge toward her window. Spotting Gregory from a hovering aircab, Jim bravely leaps through the window to confront him. In the ensuing struggle, the childlike but incredibly strong Gregory overpowers Jim and hurls him six stories out the window.

Jim survives the fall by crashing through tree branches, only to awaken in the hospital fearing the worst. However, Captain Marks reveals that Stella is safe; her visiting sister had entered the apartment during the intrusion, taking the non-fatal knife blow intended for Stella. Gregory met his end falling from the same ledge. Though Cronus proved that the preordained events could not be altered, the machine closes on a lighter note: Walker calls Jim’s hospital room to report that Cronus has just projected Jim and Stella’s upcoming wedding, sealing their future together.

How It Unfolds

The new assignment Jim Forsdon reports to the newly established Department of Future Crime in the police basement. Captain Marks introduces him to Dr. Walker and the mysterious Cronus device, which projects hazy, random visual glimpses of future events.

A vision of violence While inspecting the monitor, the men watch a horrifying, shadowy projection of a giant, limping man attack and stab a woman in her apartment. Dr. Walker estimates the murder will occur within seven to twelve days, leaving Jim with precious little time to act.

Finding the victim Analyzing minor details from the room's layout and door scanner, Jim tracks down the location to an apartment on South Central. He meets its occupant, Stella Emerson, who identifies the description of the killer as Mike Gregory, a pathetic handyman from her past assignment on Mars.

Hiding the target As Jim falls in love with Stella during dinner dates, he convinces her to stay safely with her aunt in Newark while police set up a decoy and search for Gregory. San Francisco authorities confirm that Gregory recently returned to Earth, prompting a citywide manhunt.

The inevitable confrontation Gregory evades capture, breaks out of handcuffs, and climbs the exterior ledge of Stella's apartment building to reach her window. Jim spots him from an aircab, leaps into the apartment, and fights Gregory, only to be thrown out the window into the trees below.

The future fulfilled Jim wakes in the hospital with a broken leg to find Stella alive and well. Her visiting sister had entered the apartment instead and survived the attack, fulfilling the vision without loss of life, while Cronus accurately predicts Jim and Stella’s upcoming wedding.

The People

• Jim Forsdon: A practical, determined detective assigned to the Department of Future Crime. He wants to prove that human action can change the future and prevent violent acts. Faced with the immediate threat to the woman he comes to love, he risks his own life to break the chain of preordained events.
• Captain Marks: The hard-nosed, steely-eyed head of the unit who took the job to avoid forced retirement. He wants efficiency and results, but maintains a fatalistic view that Cronus displays a fixed reality that cannot be altered, viewing their attempts at prevention as fundamentally futile.
• Dr. Howard F. Walker: The gangling, professor-like inventor of Cronus. He wants academic recognition, financial support, and more research facilities to refine his imperfect machine, viewing the tragic murder case as a vital opportunity to prove the device's undeniable worth to city brass.
• Stella Emerson: An alert, self-reliant twenty-eight-year-old private secretary with a passion for photography and a quiet life. She wants peace and safety, but finds herself at the center of an obsessive stalker's pursuit and Jim's affection, displaying genuine warmth throughout the ordeal.
• Michael Rolland Gregory: A grotesquely large former handyman from Mars who possesses immense physical strength and a childlike mind. Misunderstanding the world around him and desperate to re-establish contact with the only person who treated him kindly, his confused terror makes him deadly.

In Its Own Voice

"The picture is hazy," he went on, "and sometimes we have a hell of a time figuring out the location of whatever it is we're looking at. We also have trouble pinpointing the time of an event." — Captain Marks introducing detective Jim Forsdon to the technical limitations and raw potential of the Cronus viewer.

"Preventing it is like trying to change the past." — Captain Marks explaining his fatalistic theory on why future events seen through the machine cannot be altered.

"You can't have any idea about what's wrong with our scientific civilization until you've seen a girl blush by candlelight." — Jim Forsdon reflecting on his growing romantic admiration for Stella Emerson during their first dinner together.

What It's Really About

Underneath its fast-paced detective plot, the story explores the philosophical conflict between determinism and free will. Through the mechanism of the Cronus machine, the narrative asks whether knowing the future gives humanity the power to alter it, or if human efforts to intervene merely serve as the exact steps required to bring that preordained future to pass. Captain Marks represents the strict deterministic view, arguing that a observed future is as fixed as history. Furthermore, the tale examines the isolation brought on by technological advancement, contrasting the high-tech, futuristic urban setting with old-fashioned human connections—symbolized by candlelight, unhurried romance, and empathy for the lonely.
