Eleanor Voss wiped the sweat from her brow with the back of her gloved hand and stared at the cold slab in front of her.
The man's skin was a sickly gray, the kind of color that made the light in the morgue appear thin and weak.
A thin line of black, almost like a printed code, ran across his chest, four bars, each of different thickness, separated by tiny gaps. It was clearly a barcode, but the ink was carved into flesh, not printed.
Behind her, the hum of the refrigeration units sounded like distant insects. The air had a slight smell of formaldehyde, a scent that had become as familiar to her as her own breath. Eleanor took a breath, let it out slowly, and began the work she had been trained to do.
"Clive, you see that?" she asked without turning. Detective Clive Fletcher stood near the door, his coat still damp from the rain that had followed them from the alley where the body was found. He pulled his hat off and tucked it under his arm, the edge still dripping onto the linoleum.
"I see it," Clive said, his voice low, a little too calm for a man who had just walked past a corpse that looked like a canvas for some sick artist. "Who… could have done this?"
Eleanor shook her head. "No one we know. The only thing we have is the body and the… barcode."
The autopsy technician, Daniel, approached from the back. He was a quiet man, his eyes always glancing at the specimens and tools rather than to the people around him. He set down his tray of instruments with a soft clink and laid a scalpel on the stainless steel table.
"All set on my end, Dr. Voss," he said quietly.
Eleanor nodded. She lifted the lid of the cold case and placed a clean sheet over the body. The room felt smaller, the fluorescent lights above them glaring down. She pulled a sheet of paper from her pocket and wrote the case number: 06‑212—BarcodedCorpse. Then she started the external exam.
Step One: Documentation.
She ran a digital camera over the body, capturing the barcode from every angle. The bars were precise, each about a centimeter long, cut deep enough to feel the small bumps under the glove. She noted the depth with a ruler, then turned her attention to another strange detail, his mouth.
The man's jaw was slightly open, as if he had been trying to speak when he died. Inside the throat, just beyond the teeth, a thin, moving mass dangled from the back of the tongue. It was pale, translucent, and moved like a piece of living rope.
Eleanor's stomach knotted. She had seen parasites before, tapeworms, lung flukes, even the rare brain-eating amoeba, but this was something else.
She lifted the lid of the mouth with a small pair of forceps and gently moved the organism onto a slide. The parasite, about two centimeters long, was covered in tiny hooks along its sides. It appeared to be attached to a small, hard lump at one end, which was stuck in the soft tissue of the throat.
"Daniel, bring me a scalpel and a pair of scissors," she said in a low voice.
He obeyed, placing the tools within reach. Eleanor cut a small incision just below the jaw, careful to avoid the parasite's anchor. With a soft motion, she freed the creature and placed it in a sterile container. The parasite twisted once more, then fell still.
Step Two: Internal Examination.
She turned the body onto its back and made the usual Y‑incision, starting from the chest down to the pubic bone, then across the shoulders. The incision was clean, the skin parting like a curtain. She lifted the ribs, exposing the heart and lungs. The chest cavity was bright, the organs shining with the artificial light. Nothing else looked abnormal.
She examined the heart, feeling for any strange markings. It was normal, beating no longer but still whole. The lungs were pink, though a few dark spots showed signs of old damage, nothing out of the ordinary for a man in his late thirties.
"Any idea why someone would carve a barcode on a chest?" Daniel asked, his eyes never leaving the instruments.
Eleanor's gaze moved back to the barcode. "It could be a brand. A way to mark something. Or a message we can't read yet."
Clive leaned against the wall, his arms crossed. "You think it's a gang thing? Like a symbol to claim a body?"
"Possibly," Eleanor said, "but the precision… this isn't a random spray paint. Whoever did this knew anatomy."
She moved to the abdomen, cutting through the layers with a scalpel. The liver was a healthy brown, the kidneys smooth. She opened the stomach, expecting perhaps a hidden object, a drug packet, or a weapon. Instead, the stomach's interior was empty, save for a few undigested food particles, bread crumbs and a small piece of fruit.
She turned to the throat again, now open from the internal cut. The lump that had held the parasite was a mass like stone, hard and about the size of a pea. She probed it with a needle, feeling a rough, firm texture.
"Is it something growing?" Daniel asked.
"It could be a cyst," Eleanor replied, "but the hooks on the parasite suggest it was feeding on something."
She took a sample of the tissue around the lump and placed it in a separate container. Then she stood back, looking at the corpse as a whole, the barcode glaring from the chest, the parasite hanging like a harsh ornament.
"Let's get this to the lab," she said, "I want a full histology of the lump and DNA on the parasite. I'll also run the barcode through the criminal database, see if it matches any known patterns."
Clive nodded. "I'll start digging. Anything else?"
"Take a look at his phone," Eleanor added. "If he had a digital life, maybe we can find a link."
The three of them left the morgue in silence, the door hissing shut behind them. Outside, the rain had stopped, and the streets were shining under the streetlights. The night pressed in, like the city itself was holding its breath.

The Lab
Back in the pathology lab, Daniel set up the microscope while Eleanor prepared the samples. She placed the slice of the lump on a slide, added a drop of iodine, covered it with a cover slip, and turned the knob to bring it into focus. The view that appeared was a tangle of fibers, some smooth, some spotted, all mixed together with tiny calcified beads.
She scribbled notes: Calcified tissue containing metallic particles. Metallic particles? She frowned. She knew the lab's equipment could detect trace metals, so she called the chemist on duty.
"Hey, Tom," she said, "I need a metal analysis on this tissue."
"On it," Tom replied, already pulling up the spectrometer.
While Tom ran the test, Eleanor examined the parasite under the microscope. The creature's body was translucent, but the hooks were clearly visible, each one a tiny barbed structure, almost like a fingerprint. She noted the shape and size, then turned to the slides of the victim's blood.
The blood sample showed something odd, a dim, luminous glow when exposed to ultraviolet light. It was not the usual fluorescence of hemoglobin; it was a different wavelength, a pale green.
She called Clive back to the station. "We have something in his blood. It glows under UV light."
Clive raised an eyebrow. "Could it be a tracer? Some kind of tag?"
"Possibly. It could be a marker used to track him," Eleanor said. "Or it could be a contaminant from whatever made that barcode."
Tom returned with the metal analysis. "There's a high concentration of titanium and beryllium," he said, tapping his tablet. "And a trace of a rare earth element, yttrium."
Eleanor's mind raced. Titanium and beryllium are used in aerospace metals. Yttrium is found in certain high tech electronics. The barcode wasn't just a symbol; it might have been a physical imprint of a tool made from those metals. Someone had used a laser cutter or a scalpel with a titanium tip, carving the bars deep into the flesh.
"Clive, I need you to pull up any reports of missing high tech equipment from local manufacturers," she said. "And check if there have been any reports of strange markings on bodies."
"Will do," he replied.

The Detective's Trail
Clive spent the next few hours in the precinct, scrolling through databases, calling contacts. He found a recent theft at a small tech firm, Vanguard Micro Systems. The report listed stolen items: a prototype laser cutter, a batch of titanium blended metal blades, and several containers of rare earth metals. The theft had taken place three weeks earlier, and the case was still open, no suspects, no leads.
He called Eleanor back to the station.
"Vanguard had a laser cutter stolen," he said, sliding a copy of the police report across the table. "The cutter's specifications match the metals we found in the tissue."
Eleanor looked at the report. The cutter was described as a "precision barcoding laser," used for creating microscopic barcodes on thin slices of computer chips. It could mark at a depth of micrometers, but with enough power could cut through soft tissue.
"What if someone used it on a human?" she whispered.
"Then the barcode would be perfect," Clive said, "and the person could be tracked. Maybe the glow in the blood is a tracer the same group uses for their products."
Eleanor stared at the barcode again. "If we decode it, maybe it will tell us something."
She took a photo of the barcode with a high resolution camera, then used a free online decoder. The code translated to a series of numbers: 019‑837‑54. She typed it into a search engine, and a single result popped up, a product code for a Vanguard Micro Systems inventory item: BarcodeEngraver Model 019‑837‑54, discontinued five years ago. It was a handheld device, used for marking medical implants.
"It's a medical device," Eleanor said. "A tool to mark implants. Someone repurposed it for… for a killing."
Clive looked tense. "Who would have access to such a device? And why the parasite?"
"Perhaps the parasite is part of a delivery system," Eleanor mused. "What if the parasite carries something... maybe a virus or a nanotech?"
She pulled the parasite out of the freezer, placed it under a lamp, and watched it twitch. It looked asleep now, but the hooks on its body could latch onto tissue, maybe even inject something.
"Let's run a PCR test on it," Daniel suggested, already setting up the equipment. "See if it has any genetic material we recognize."

After Midnight
Hours slipped by. The lab was quiet except for the soft beeps of machines. Eleanor's eyes were heavy, but she forced herself to stay awake. She knew that if the parasite held a pathogen, it could be highly dangerous. She also felt a growing worry, a small thread of fear twisting in her mind.
The PCR results came back in minutes. The machine printed a single line: UNKNOWN.
Eleanor stared at the word. "It's not bacterial, not viral, not fungal," she said. "It's a placeholder."
