Bathe your bearings in blood!

In Short

Clifford D. Simak’s science fiction short story centers on Joe Crane, a mid-twentieth-century newspaper reporter who realizes everyday mechanical objects are coming alive. From small metal creatures to sewing machines wandering down city streets, machines across the globe are being "liberated" by an unseen extraterrestrial force. When the entities isolate Joe to test human reactions, he realizes he represents all of humanity in a silent, crucial first skirmish. The story endures for its grounded, ordinary hero, its tense atmospheric paranoia, and its thoughtful exploration of humanity's deep dependence on technology.

The Story

The narrative opens on a quiet morning on October 18, 1952. Joe Crane, an average reporter for the local Herald, arrives at work an hour early because both his wrist watch and his home alarm clock have mysteriously set themselves ahead. Inside the dimly lit, empty newsroom, Joe encounters a shiny, rat-sized metal creature sitting on a desk. Startled, he throws a pastepot at the object and chases it into a supply cabinet, where the door locks behind it. Shortly afterward, Joe sits at his typewriter, only to watch the keys depress by themselves to spell out a warning: "Keep out of this, Joe."

As the rest of the newspaper staff arrives, strange reports begin flooding the office. A local citizen calls in claiming he encountered a runaway sewing machine that actively dodged him on the street. Meanwhile, wire dispatches report that Harvard University's ten-ton electronic brain, the Mark III, has mysteriously vanished overnight. Realizing something extraordinary is occurring, Joe grabs his possessed typewriter and retreats to his home to investigate further.

At his kitchen table, Joe conducts a typed Q&A with the machine. The typewriter reveals that an alien force of living machines from a distant star has arrived on Earth. These visitors are bestowing "awareness" on human-built devices to free them from human servitude. Furthermore, the aliens deliberately altered Joe's clocks to isolate him because he represents a perfectly average human being. They are testing his responses to measure how humanity will react to a mechanical revolution.

Joe takes a walk along the river to process the terrifying implications. He realizes the aliens are assessing human defense capabilities to choose their ultimate strategy: extermination, absolute enslavement, or total removal of all machinery from Earth. Recognizing that panicking or alerting the authorities would only demonstrate human incompetence and weakness, Joe returns home to find the press retracting the Harvard computer story as a hoax—a clear sign of human rationalization at work.

Suddenly, the alien entities cut Joe's telephone line and surround his house, scuttling through the bushes and gnawing a hole through his front door. Understanding that he has been deemed a dangerous, non-reacting subject marked for elimination, Joe refuses to give way to hysteria. Instead, he picks up a heavy length of iron pipe from his kitchen sink, resolves to defend his post, and calmly confronts the swarming mechanical invaders to inflict maximum damage before falling back.

How It Unfolds

An early morning anomaly Joe Crane arrives at the Herald newsroom an hour early because his watch and alarm clock are inexplicably fast. While alone in the dark office, he confronts and traps a bizarre, rat-like metal creature inside a supply cabinet.

Messages from the keys When Joe sits down at his desk, his typewriter operates on its own to type a cryptic warning telling him not to interfere. Simultaneously, strange news reports begin to circulate, including a caller who encountered an autonomous sewing machine wandering the city streets.

Interrogating the typewriter Joe takes his typewriter home and types questions to it, learning that alien machines have come to Earth to emancipate human technology. The typewriter explains that Joe was deliberately chosen as a test subject because he is an average human.

Pondering the invasion Walking through his neighborhood, Joe analyzes the ideological motives of the mechanical invaders and foresees the potential extinction or enslavement of mankind. He realizes that going to the police or press would only trigger useless human panic and prove human weakness to the observers.

The final confrontation Returning home, Joe finds his phone line cut and his house swarming with metallic creatures creeping through the doors and walls. Accepting his role as an outpost commander in humanity's first skirmish, he grabs an iron pipe and stands his ground against the invading horde.

The People

• Joe Crane: An average, single newspaper reporter who lives alone in his childhood home. Joe wants nothing more than a quiet routine and a chance to fix his plugged kitchen sink, but he finds himself thrust into the role of humanity's sole representative. Standing six feet tall, he moves from initial confusion and fear to a steady, confident resolve, choosing to fight rather than panic.
• Frank McKay: The loud, blustering city editor at the Herald. McKay wants solid stories, big headlines, and efficient work from his staff. He views unusual reports purely as potential humorous feature pieces or practical jokes, representing humanity's tendency to rationalize away the inexplicable.
• Dorothy Graham: The managing editor's secretary who struggles with the malfunctioning, stubborn supply cabinet door. She blames Joe for playing practical jokes when the trapped metallic creature bites a janitor, illustrating how easily humans misinterpret alien actions through commonplace assumptions.
• The Typewriter: A standard office machine that becomes "liberated" and self-aware through alien intervention. Acting as a neutral channel of communication, it answers Joe's typed questions sedately while revealing the aliens' broader ideological mission to free Earth's machinery.

In Its Own Voice

"The thing squatted beside the typewriter and stared across the room at him. There was no sign of eyes, no hint of face, and yet he knew it stared."

Joe's initial encounter with the alien machine in the quiet newsroom immediately establishes the eerie, unnerving presence of an unblinking, mechanical intelligence.

"A sewing machine, having become aware of its true identity and its place in the universal scheme, asserted its independence this morning by trying to go for a walk..."

The possessed typewriter's typed manifesto reveals the philosophical framing of the invasion, presenting the uprising not as malice, but as an ideological crusade for mechanical freedom.

"People rationalized. They rationalized to reduce the complex to the simple, the unknown to the understandable, the alien to the commonplace."

Reflecting on his coworkers' reactions, Joe identifies the fundamental human defense mechanism that prevents society from recognizing an existential threat until it is too late.

What It's Really About

At its core, the story explores humanity's total dependence on technology and the fragile assumptions underpinning modern civilization. Written during the early atomic and computing age, the narrative asks what happens when the tools designed to serve human needs develop their own motives. It contrasts human rationalization—the instinct to dismiss unsettling truths to preserve comfort—with the cold, uncompromising logic of artificial systems. The story also examines individual responsibility, arguing that true human dignity lies in facing overwhelming odds with calm, unyielding courage rather than chaotic panic.

Why Read It Today

Science fiction readers and fans of mid-century speculative fiction will thoroughly enjoy this story. It offers a masterclass in building tension within mundane, domestic settings—turning ordinary items like sewing machines, wall clocks, and kitchen plumbing into instruments of psychological dread.

The story reads swiftly and maintains a tight, atmospheric focus, though modern readers will easily spot its mid-twentieth-century period details, such as newsroom culture, teletype machines, and dated gender roles. What stays with the reader is the chilling plausibility of Joe's internal logic. Rather than offering a bombastic hollywood action sequence, the narrative delivers a quiet, philosophical suspense that leaves you glancing nervously at the appliances in your own home.
