Bonus points if they figure out Dexter's secret murders because of a story they're writing
Bay Harbor Research
Dexter Morgan x Reader
You had known Debra Morgan longer than most people in Miami ever would. Years earlier, when she was still working undercover as a street-level prostitute for a task force that never quite knew what to do with her, you had been the real thing. Cheap rooms, careful calculations of risk, the particular kind of exhaustion that came from selling time and body in equal measure. You never romanticized it, and Deb never pretended the work was glamorous. The two of you shared cigarettes on curb edges and the occasional quiet understanding that neither of you belonged fully to the world you were navigating. When she finally left that assignment, she kept your number. When you left the life entirely, you kept hers.
Now you wrote books.
The current manuscript was a long, carefully researched novel about the Bay Harbor Butcher. You had already spent months on public records, autopsy summaries, and the limited crime-scene photographs that had leaked or been released. Still, the technical gaps frustrated you. Blood patterns, rates of exsanguination, the practical realities of body disposal at sea—those details needed to feel correct if the book was going to hold any weight. Deb had listened to you complain over the phone one evening and, after a long silence, said she knew someone.
“My brother’s a blood-spatter analyst for Miami Metro,” she told you. “Dexter. He reconstructs scenes for a living. If anyone can tell you how long it takes someone to bleed out from a gut wound without looking it up in a textbook, it’s him. I’ll text him. Don’t be weird.”
You were not weird. You were thorough.
Two days later you stood outside a modest apartment building in a quiet stretch of Miami that did not advertise itself. Dexter Morgan opened the door wearing a plain dark shirt and an expression that managed to be both polite and carefully neutral. He was taller than you had expected, neat in the way of someone who measured everything, including the distance between himself and other people.
“Deb said you needed help with research,” he said.
“I do. Thank you for agreeing to this.”
He stepped aside. The apartment was clean to the point of severity. A single couch, a low table, books arranged by height, no unnecessary decoration. The living-room floor was clear except for a few folders already laid out in a precise grid.
“I thought the floor might be easier,” he said. “More space to spread things out.”
You sat cross-legged opposite him, notebook open, pen ready. He sat with one knee drawn up, a posture that looked relaxed until you noticed how little he actually moved. For the first twenty minutes the conversation stayed clinical. You asked about arterial spray versus venous flow. He answered with the calm precision of someone who had measured both. You asked about the effect of water temperature on decomposition rates for bodies recovered from the bay. He gave you ranges, caveats, and the variables that most people overlooked.
Then the questions grew more specific.
You were both quiet for a stretch, reviewing a set of photocopied crime-scene diagrams Deb had somehow obtained for you. The only sounds were the soft turn of pages and the distant hum of the air conditioner. You looked up.
“Theoretically,” you said, “how long would it take for a person to bleed out from a stab wound to the stomach?”
Dexter’s eyes lifted from the paper. For a fraction of a second something unreadable moved behind them. Then the professional mask settled again.
“Depends on several factors,” he answered. “Depth, angle, whether major vessels are involved, the victim’s blood pressure and clotting response. A clean wound that severs the abdominal aorta can kill in under two minutes. Something that only perforates bowel and smaller vessels might take hours if the person remains still. Most people don’t remain still.”
You wrote it down. “And if the knife is left in place?”
“It can act as a partial plug. Removing it often accelerates the bleeding. That’s why first responders are trained not to pull blades out in the field.”
“Right.” You tapped the pen against the page. “What about the difference in blood loss if the person is upright versus lying down?”
He answered without hesitation. Gravity, hydrostatic pressure, the way the abdominal cavity could hold a surprising volume before external signs became obvious. You listened, nodded, and moved on to the next question. He never asked why you needed this level of detail. He treated every query as legitimate research, the same way a specialist might answer a medical student.
An hour later the light in the room had shifted. You were both still on the floor. Papers had migrated into overlapping stacks. At one point you reached for a diagram at the same moment he did. Your fingers brushed. Neither of you pulled back immediately. The contact lasted perhaps two seconds longer than necessary before he released the page and you took it. Neither of you commented.
You continued.
“If someone wanted to minimize blood evidence at a scene,” you said carefully, “what would be the most practical methods that still left the body usable for dumping?”
Dexter considered the question with the same detached interest he had shown everything else. “Plastic sheeting. Controlled environment. Positioning the body so that drainage is directed into a contained area. Some people use tarps with raised edges. The goal is to keep the blood from soaking into flooring or leaving transfer patterns that can be matched later.”
“And cleaning afterward?”
“Bleach is common but imperfect. It can degrade DNA, but it also leaves its own chemical signature. Hydrogen peroxide can foam in the presence of blood residue, which is useful for detection if you’re looking for it. Most people who try to clean thoroughly still miss something. Blood gets into seams, under baseboards, into the weave of carpets that look clean to the eye.”
You wrote steadily. The conversation never became personal. He did not ask about your past. You did not ask about his. The only acknowledgment of how unusual the subject matter was came in the occasional pause he took before answering, as if sorting the information into the category of professional curiosity rather than anything else.
Later that same afternoon you asked about the physics of blood drying on different surfaces—tile versus wood versus fabric—and how long after death a body could still produce usable spatter if moved. He answered each point with measured detail. When you asked whether a person who understood blood evidence intimately would be better or worse at concealing it, he gave a small, almost invisible shrug.
“Knowledge cuts both ways,” he said. “You know what investigators look for, so you know what to avoid. You also know how easy it is to leave something behind that you didn’t intend.”
The session ended when the light outside had turned the color of late afternoon. You gathered your notes. He stood and offered a hand to help you up from the floor. The contact was brief, polite, and again lasted a fraction longer than the simple act required. You noticed. You did not comment.
“Same time next week?” you asked at the door.
“If you still have questions.”
“I will.”
He nodded once. The door closed with a soft, final sound.
The following week you returned with a new set of queries. This time you brought printed photographs of known Butcher dump sites—blurry aerial shots and a few closer images of plastic-wrapped remains pulled from the water. Dexter examined them without visible reaction.
“The wrapping is consistent,” he observed. “Heavy-duty plastic, sealed with care. The knots are practical rather than decorative. Whoever did this understood that the goal was containment during transport and delayed discovery once the bodies were in the water.”
You sat on the floor again, closer to the center of the room this time. He mirrored the position. The questions continued in the same quiet rhythm.
“How long does it take for seawater to compromise fingerprints on plastic?”
“Variable. Temperature, salinity, microbial activity. Days to weeks depending on conditions. Prints on the inner surface of the wrap would last longer if the seal held.”
“And tool marks on bone? If the dismemberment was done with a saw versus a knife?”
He described the difference in kerf patterns, the way a power tool left more regular striations, the way a hand saw produced more variable marks that could still be matched to a specific blade if the tool was recovered. You took notes until your hand cramped. When you set the pen down and flexed your fingers, he watched the motion for a moment longer than conversation required, then looked away.
“You’re very thorough,” he said.
“The book needs to feel real. Readers can tell when the details are invented.”
“Most readers wouldn’t know the difference.”
“I would.”
He accepted that without argument.
A third session followed the same pattern. You asked about the stages of livor mortis and how they could be used to determine whether a body had been moved after death. You asked about the practical difficulties of cutting through cervical vertebrae versus larger joints. You asked, almost casually, how much blood a human body actually held and how that volume changed the logistics of cleanup.
Dexter answered every question. He never once suggested the subject matter was strange. When you paused after a particularly detailed inquiry about the time required for a body to sink versus float after certain preparatory steps, he simply waited until you were ready to continue. The silence between questions felt companionable rather than strained. Two people sharing a specialized language that most of the world preferred not to speak.
At one point you shifted position and your knee brushed his. Neither of you adjusted immediately. The contact remained for several heartbeats before you both moved at the same time, creating a careful space again. No words were exchanged about it.
By the fourth meeting the floor of his living room had become a familiar workspace. Folders, printed photographs, your notebook with its increasingly dense pages of diagrams and time estimates. You asked about the smell of a body in different stages of decomposition and how an investigator might distinguish it from other organic decay. You asked whether a person who worked with blood every day would develop a different sensitivity to its presence—whether the scent or the color or the particular way it dried would register more strongly.
Dexter considered that one longer than usual.
“Possibly,” he said. “Familiarity can dull some responses and sharpen others. You stop noticing the ordinary and start noticing the deviations.”
You wrote that down.
The light had begun to fade when you finally closed the notebook. Your shoulders ached from leaning forward for so long. He noticed and stood, offering the same brief hand as before. This time when your palm met his, the contact lasted long enough that you felt the warmth of his skin and the slight roughness of a small scar near the base of his thumb. He released first.
“You’ve been useful,” you said at the door. “More than I expected.”
“Deb said you were serious about the research.”
“I am.”
He gave a small nod. “Next week, then.”
“Next week.”
You walked to your car with the notebook held against your chest. The questions you had asked circled in your mind, precise and clinical. Somewhere underneath them was the quieter knowledge that the man who answered so readily understood the material at a level that went beyond textbooks and training courses. You did not examine that thought too closely. Not yet.
The manuscript grew. Pages filled with accurate blood volumes, realistic timelines for exsanguination, the practical constraints of disposing of a body in open water. Dexter’s answers gave the fiction its spine. Each session on his living-room floor added another layer of correctness that no amount of public-source research could have supplied.
And still the questions continued, quiet, specific, and unanswered by anyone else you knew.
The invitation had been casual. Debra Morgan texted late on a Thursday and suggested drinks at a bar that was neither fashionable nor particularly clean, the kind of place where the lighting stayed low and the bartenders did not ask questions. You met her there. She was already two beers ahead of you when you arrived, sleeves rolled, posture loose in the way that meant she had decided the night belonged to conversation rather than work.
“You still talking to my brother about that book?” she asked once the second round arrived.
“Yes. He’s been helpful.”
Deb snorted into her glass. “Helpful. That’s one word for it. Dex is specific about everything. Always has been. Blood patterns, schedules, the exact angle a body falls when the knees give out. He notices shit most people walk past. When we were kids he used to rearrange the silverware drawer if Mom put the forks in the wrong slot. Drove her crazy.”
You listened without interrupting. Deb rarely spoke about her brother at length. The alcohol and the low noise of the bar seemed to loosen the usual restraint.
“He’s got this whole system for everything,” she continued. “Laundry sorted by color and fabric weight. Knives in the kitchen block ordered by size. Even the way he parks the car—same spot, same distance from the curb every single time. I used to think it was just him being a freak about control. Now I think it’s how he keeps the world from spinning too fast.”
She took another drink. “You left a pen at his place last week. Blue one, the kind with the rubber grip. He kept it. Put it in the cup on his desk like it belonged there. I saw it when I stopped by to borrow a charger. Told him he should give it back. He said it was fine, you might need it next time.” Deb grinned, a little crooked. “I think he’s interested. In you. In a quiet, Dexter kind of way. Don’t tell him I said that. He’d deny it until the heat death of the universe.”
The information settled in your chest with an unexpected weight. A single pen. Retained. Placed deliberately among his own things. Deb interpreted the act as mild interest, the sort of small claim a careful man might make when he did not know how to express anything larger. You felt something colder move along your spine. The precision she described—the ordered knives, the exact parking, the habit of noticing what others overlooked—aligned too neatly with the man who had answered every forensic question without hesitation. The same man who understood, in measured detail, how long a body could remain useful after certain preparations.
You did not correct Deb’s assumption. You only nodded and let the conversation drift to other subjects: her latest case, the weather, a complaint about a partner who talked too much during surveillance. When the night ended you drove home with the image of that blue pen fixed in your mind.
Over the following days the thought returned with increasing frequency. You began to examine the pattern of your own sessions with Dexter. The way he never needed to consult notes. The calm with which he discussed arterial spray and the practical limits of plastic sheeting. The small scar near the base of his thumb that you had felt when he helped you stand. Deb’s words supplied a frame. Specific. Controlled. Interested enough to keep a pen that did not belong to him.
Interest, however, was no longer the only word that applied.
You started watching him.
It began with small adjustments to your own schedule. You learned the approximate time he left Miami Metro each evening by parking two blocks away and waiting. His car—a nondescript sedan—appeared with reliable consistency. He drove the same route home, stopped at the same grocery store on alternating Tuesdays, bought the same limited selection of items. On one evening you followed at a careful distance and watched him carry a single bag into his building. The next night you observed him leave again after dark, drive to a quiet stretch of the marina, and sit for forty minutes without exiting the vehicle. He did nothing overtly unusual. He simply sat, hands on the wheel, gaze fixed on the water. When he finally left, you remained until the taillights disappeared.
The routines accumulated. Early morning runs along a fixed path. A weekly visit to a self-storage facility on the edge of the city, always at the same hour, always alone. The way he checked the locks on his apartment door twice before walking away. None of it constituted proof of anything. Taken together, the pattern formed a silhouette that matched the careful, methodical figure described in the police files you had studied for the book. The Bay Harbor Butcher had never been careless. Neither, it seemed, was Dexter Morgan.
You told no one. The observation remained private, a parallel research project conducted in silence.
One evening you suggested a change of location for the next research session. Your apartment, you said, would give you easier access to the reference materials you had collected. Dexter agreed without visible concern. He arrived at the arranged time carrying a slim folder and the same neutral expression he wore in every previous meeting. You showed him in, offered water, and led him to the low table in the living room where you had already spread the relevant pages.
This time the questions began differently.
You sat across from him, notebook open, and spoke in the same even tone you had used before. “I’ve been thinking about the packaging. The plastic used on the recovered bodies. The seals were consistent across multiple dumps. What kind of heat source would produce that level of uniformity without melting the material?”
Dexter’s gaze moved from the printed photographs to your face. He answered without hesitation. “A controlled heat sealer, industrial grade. Something with adjustable temperature settings so the plastic fuses cleanly along the edge without warping. Handheld versions exist, but the consistency across multiple bodies suggests either a fixed unit or a very practiced hand.”
You wrote it down. “And the knots. The way the plastic was secured before sealing. Some of the recovered sections still had remnants of the original ties. They weren’t random.”
“No,” he said. “They were functional. Tight enough to hold during transport, positioned to keep the contents from shifting. Someone who understood weight distribution and how a wrapped form moves when carried.”
You turned a page in your notebook. The next question sat ready. “If the goal was to keep the bodies intact long enough for ocean disposal, what would be the optimal window between preparation and release? Too soon and residual air or gases could cause premature floating. Too late and decomposition would complicate handling.”
Dexter was quiet for a moment. The air conditioner hummed. Outside, traffic moved in the distance.
“Twenty-four to thirty-six hours under controlled temperature,” he said finally. “Cool enough to slow bacterial activity, warm enough to avoid rigidity that makes positioning difficult. The plastic itself buys additional time once the body is in the water, but the initial preparation has to account for the delay between the last cut and the final drop.”
You nodded as if the answer were simply useful research. Inside, the chill from Deb’s earlier comments returned with greater force. The level of practical detail he offered went beyond standard forensic reconstruction. It sounded like lived knowledge.
You continued. “The wounds on the earlier victims showed a preference for certain joints. Shoulders, hips, the places where the limbs could be separated with the least resistance. Is that efficiency, or is there another reason to choose those points?”
“Efficiency,” he replied. “Less bone density to cut through. Cleaner edges. Less chance of the tool slipping and creating secondary marks that could be matched later. A person who works with bodies regularly would learn that quickly.”
“And if that person also understood blood evidence?”
“Then they would know exactly how much of a mess those cuts can make if the body isn’t properly drained first.” His voice remained even. “Positioning matters. Gravity matters. Time matters.”
You let the silence sit between you for several seconds. Then you asked the next question, softer this time. “How would someone who knew all of that still leave enough of a pattern for investigators to eventually connect the cases? Or would they deliberately leave just enough consistency to create a signature while remaining untraceable?”
Dexter’s eyes met yours. For a brief interval the professional mask thinned. Something older and more watchful looked out from behind it. Then the expression smoothed again.
“Signatures are dangerous,” he said. “Consistency can be a liability. The smarter approach is variation within a controlled method. Change the dump sites. Alter the exact sequence of cuts. Keep the core technique reliable enough that the work stays clean, but never identical enough to form an easy profile.”
You wrote the words down carefully. Your hand was steady. The notebook page filled with precise notes that no longer felt like fiction.
The session continued for another hour. You asked about the practical difficulties of working alone, the time required to clean a space thoroughly enough that luminol would return minimal results, the way certain plastics retained fingerprints longer than others when exposed to salt water. Each answer came without reference materials. Each answer carried the quiet authority of someone who had measured these variables in practice rather than theory.
At one point you reached across the table for a photograph at the same moment he did. Your fingers brushed. Neither of you pulled back at once. The contact lasted long enough for you to feel the warmth of his skin and the slight ridge of that small scar again. Then he released the page and sat back.
“You’ve been more specific tonight,” he observed.
“The book is reaching the sections that need accuracy,” you said. “I don’t want to invent details that a real investigator would know are wrong.”
He accepted the explanation with a slight nod. “Most writers invent. You’re asking the questions that matter.”
When the light in the room had shifted to full evening, you closed the notebook. Dexter stood, gathered his folder, and moved toward the door. You walked with him. At the threshold he paused.
“Same time next week?” he asked.
“Yes.”
He left. You locked the door behind him and stood for a long moment in the quiet apartment, the notebook still in your hand. The questions you had asked circled back through your mind, each one sharper than the last. The man who answered them so readily understood the work of the Bay Harbor Butcher at a level that textbooks and crime-scene reports could not fully explain.
You sat down at the table again and opened the notebook to a fresh page. This time you did not write research notes. You wrote a single name, underlined once, and then closed the cover.
Outside, the city continued its ordinary noise. Inside, the pattern had begun to resolve.
You arrived at Dexter’s apartment with the notebook held tight against your side and the decision already made. The previous session had left no comfortable room for continued pretense. The answers he had given—precise, practical, unhesitating—had moved past research and into something that felt like confession without words. Tonight you intended to set the notebook on the table, look him in the eye, and ask the question directly.
You knocked once. Waited. Knocked again, harder.
No answer.
You tried his phone. It rang through to voicemail without interruption. You stood on the narrow walkway outside his door and looked down at the parking lot. His car was not in its usual space. The spot sat empty under the late-afternoon light.
He was not home.
The heat of the summer afternoon pressed against the back of your neck. You could have left. You could have returned another day with the same notebook and the same intention. Instead you stayed where you were and considered the lock.
Years earlier, when the work had been different and the rooms less permanent, you had learned certain practical skills. Locks were rarely complicated when you understood their limits. You carried a thin set of picks in the side pocket of your bag for reasons you had never fully retired. The hallway remained empty. You worked quickly, feeling for the pins, applying steady pressure until the cylinder turned. The door opened with a soft click. You stepped inside and closed it behind you.
The apartment was exactly as you remembered: ordered, sparse, almost severe. The living room held the same low table, the same carefully aligned books, the same absence of unnecessary objects. You set the notebook down and began to look.
You moved through the space methodically. Kitchen first. Drawers contained utensils arranged by size and function. The refrigerator held minimal contents, each item placed with deliberate spacing. No photographs. No personal clutter. The bathroom revealed the same precision—towels folded to identical dimensions, toiletries lined in a straight row. Nothing that spoke of the work you suspected.
The bedroom was equally controlled. The bed was made with hospital corners. The closet held shirts hung at identical intervals, shoes placed in a single neat row. You checked the underside of the mattress, the backs of drawers, the narrow space behind the headboard. Nothing.
You returned to the living room. The heat inside the closed apartment had grown noticeable. Sweat gathered at your temples. You crossed to the wall unit and reached for the controls, intending only to start the air. The front panel shifted under your hand. It came free with almost no resistance. No visible screws held it in place. The entire face of the unit lifted away as if it had been designed to do so.
Behind the panel, set into the cavity that should have contained only machinery, sat a dark wooden box.
You stared at it for several full seconds. Then you lifted it free.
The box was heavier than it looked. You carried it to the low table and opened the lid.
Inside, arranged in precise rows, were glass microscope slides. Each one held a single drop of blood, sealed and labeled in the same careful handwriting. Dates. Initials. Small notations that meant nothing to an outsider and everything once the pattern became clear. You counted them without meaning to. There were far more than the official victim list had ever acknowledged.
Your breath left you in a slow, controlled exhale. The notebook still sat on the table where you had placed it. The questions you had planned to ask no longer mattered. The collection in front of you answered every one of them.
Dexter Morgan was the Bay Harbor Butcher.
You remained still for a long moment, the open box between your hands. Then training older than the book reasserted itself. Evidence left disturbed became its own problem. You began to return the slides to their exact positions, matching the order you had found them in, closing the lid with care.
The sound of a key in the lock reached you just as you lifted the box to slide it back into the wall unit.
The door opened.
Dexter stepped inside carrying a single grocery bag. He stopped the instant he saw you. His eyes moved from your face to the open air-conditioning panel, then to the box still in your hands. The grocery bag lowered slowly to the floor. He closed the door behind him without looking away.
For several seconds neither of you spoke.
“You shouldn’t be here,” he said at last. His voice was quiet, almost conversational.
You set the box down on the table but did not step away from it. “I came to talk. You weren’t answering.”
“So you broke in.”
“Yes.”
He studied the open panel, then the box. Something in his posture shifted—not panic, not rage, but a careful recalibration. He set his keys on the counter with deliberate neatness.
“How long have you known?” he asked.
“I didn’t. Not until this.” You gestured at the slides. “But I was getting close. The questions you answered. The way you never needed to look anything up. Deb talking about how specific you are. The pen you kept.”
Dexter’s gaze flicked briefly to the desk where the blue pen still sat in its cup. He said nothing.
“I followed you,” you continued. The words came out steady. “Not every day. Enough. The storage unit. The marina. The same routes, the same times. It started looking less like research and more like something else.”
He walked farther into the room, stopping on the opposite side of the table. The box remained between you. He did not reach for it.
“And now you have proof,” he said.
“Yes.”
Silence settled again. The open air-conditioning panel hummed faintly with residual electricity. Outside, a car passed on the street below. Inside the apartment the only movement was the slow rise and fall of his breathing.
“What are you going to do?” he asked.
You looked down at the slides, at the careful labels, at the years of private collection arranged like a catalog. The notebook still waited on the table, filled with questions that had led exactly here.
“I haven’t decided,” you said.
Dexter’s eyes stayed on yours. The professional mask he wore at Miami Metro was gone. In its place was something more exposed and far more dangerous—an assessment of risk, of options, of the woman who now stood in the middle of his carefully ordered life with the evidence in plain view.
“You realize what this means,” he said.
“I do.”
He nodded once, a small, precise motion. Then he pulled out a chair and sat, as if the conversation had simply moved to the next logical stage. He did not try to take the box. He did not move closer.
“Then we should talk,” he said.
You remained standing for another moment, the weight of the discovery still settling through you. Finally you drew out the opposite chair and sat as well. The notebook lay within reach. The blood slides rested between you like an open confession.
The air in the apartment stayed warm. Neither of you reached to replace the panel.
Outside, the summer evening continued. Inside, the only sound was the quiet, measured conversation that had nowhere left to hide.
