The tablet's glow carved a rectangle of pale light across Juno's lap. She held it at arm's length, the way she had learned to hold things that could wound her. Around her, the ship's medical bay breathed its slow mechanical breath, the overhead panels casting everything in the flat, antiseptic blue of a morgue. Somewhere beyond the sealed door, a pipe ticked. Somewhere further, the ship went on without its captain.
Juno read the report again.
The words did not change. They sat on the screen with the patient weight of things that had already happened and could not unhappen.
Cause of death: respiratory depression secondary to intentional overdose of triazolam-class sedative.
Manner of death: self-administered suicide.
Chief Medical Officer: Imogen Park, MD.
She scrolled back up. The captain's name was there, formal and small, YUKI TANAKA, RANK: CAPTAIN, SERVICE NUMBER redacted for privacy. Below it, time of death estimated between 0347 and 0412 shipboard standard. Below that, the toxicology summary. Below that, the attending physician's signature, a neat block of letters curling into Park's name. Below that, a single line she had already memorized.
The decedent was found deceased in his quarters. No signs of struggle. No defensive wounds. No injection sites inconsistent with prior medical history. No foreign DNA. No forced entry. No note.
Juno closed her eyes. She did not close them long. Closing her eyes for too long meant hearing the transmission burst again, the shriek and the silence after it, the way the comm station had smelled of scorched polymer for three days.
She opened her eyes. She read the report again.
The tablet weighed almost nothing. That was the obscene part. The captain had been a substantial man. Broad across the shoulders, tall, with hands that could palm a regulation datapad the way a parent palms a child's face. He had weighed something. He had occupied space. Now his death was a document weighing four hundred grams and change, held by a woman who could feel the bones of her own wrists through the sleeves of her duty jumper.
She set the tablet face-down on the thin mattress of the observation cot. The screen dimmed but did not go dark. She could not bring herself to tap it fully off. There was still a chance, the small stubborn chance she had carried since she had been dragged out of the comm pit, that reading the report one more time would reveal a flaw. A misspelling. A contradiction. Something to crack the seal on the verdict and let the air back in.
There was no misspelling.
The tablet lay there. The cot smelled of bleach and the faint sweet note of the analgesic spray they used on the sheets. Juno's own breath was shallow, the kind of breathing she had picked up in the weeks after the transmission event, the kind that arrived when her body remembered before her mind did that the air supply could fail.
She picked the tablet up.
The internal temperature of the medical bay read seventeen degrees Celsius on the wall display. That was the doctor's preference, Imogen Park's preference, kept cold for the preservation of specimens and the clarity of the staff. Juno pulled the thin blanket higher on her shoulders. She had not asked for it. A nurse had left it there an hour ago, possibly out of pity, possibly out of habit, and Juno had not refused it because refusing it would have required a sentence she did not have.
A soft chime. The door to the medical bay slid open on its track with the quiet hiss of a properly sealed bulkhead.
Doctor Imogen Park entered carrying a second tablet and a cup of something that steamed. She wore her duty whites, her hair pinned close, a small silver pin in the shape of a medical caduceus at her collar. Her face was composed in the way that Juno's grandmother had once called a still pond: nothing on the surface, anything underneath.
"You are still here," Park said. Her voice was soft, the consonants rounded, the kind of voice you might trust with a secret or a vein. She set the cup down on the narrow steel ledge by the cot. "This is chamomile. It is not going to fix anything. I am not pretending it is. But it is warm, and you have been in this bay for four hours."
Juno looked at the cup. She did not pick it up. "The toxicology summary lists a serum concentration of point-zero-four milligrams per liter."
"Yes."
"That is within the therapeutic range for induction of sleep. It is not a recreational dose. It is not even a strong clinical dose."
"No," Park said. She pulled a small rolling stool from under the counter and sat. The stool was set low. She had to look up at Juno. She did not seem to mind. "It is the dose a competent physician would write for a person who wished to sleep through the night without waking."
"And yet."
"And yet," Park repeated, without inflection. She let the silence hold for a moment. "Juno. I have signed the report. I will not unsign it. I am going to tell you what is in it, in my own words, and you are going to listen, and then you are going to go back to your quarters and try to sleep. That is the order of operations. I am not issuing this as a medical officer. I am issuing it as the woman who has now watched you not sleep for nineteen days."
"I slept on Tuesday."
"For forty minutes. With the lights on. In a chair."
Juno's mouth twitched. It was not quite a smile. "How did you know about the chair."
"Because I am the chief medical officer and also because Lieutenant Okafor mentioned it in passing while she was pretending not to worry about you. Which she is doing badly. They all are."
The chamomile cooled in its cup. Juno stared at the surface of it, at the tiny ring of oil that caught the overhead light.
"Captain Tanaka was on no medication," Juno said. "That is in his file. That is in his last physical. That is in his annual. No anxiolytics. No hypnotics. No off-label anything. He refused the sleep aids the corps offers for long-haul crews. He told me once that he considered them a moral failure."
Park nodded slowly. "I have his file. I have his last physical. I have his pharmacy log. There is no prescription under his name. There is no over-the-counter purchase on his personal account. There is no contraband flagged in his quarters during the last sweep."
"Then how."
"That," Park said, "is the question."
The word then how sat between them, small and enormous.
Juno picked up the chamomile. She held it the way she held the tablet, at a careful distance, and she drank. It was too sweet and not sweet enough. It tasted like someone else's idea of comfort.
"He would not have done this," Juno said.
"I have to be careful with that sentence," Park said. "I have to be careful because you are not the only person who has said it to me. The whole senior staff has said some version of it. Lieutenant Okafor said it with her arms crossed. Commander Vael said it twice. Ensign Berro said it with a face I can only describe as politely furious. You are saying it now. You are all, in different ways, telling me that the captain you knew would not have done this."
"Correct."
"And I have to tell you," Park said, "that in my experience, no one ever thinks the person they knew would have done this. That is true of every overdose I have ever seen. It is true of every gunshot in a bedroom. It is true of every body found on a bridge or under a tree or in a parked car. The people who are left behind always say some version of he would not have done this. And the people who died always, in some way, did."
Juno set the cup down. The ring of oil had spread.
"With respect," Juno said, "you did not know him."
"No," Park said. "I joined this vessel fourteen months ago. You joined it three years before I did. You worked under him. You transmitted under him. You are the only surviving member of the comm team that was on shift the night of the incident. So yes. You knew him longer and better than I did. That is not in dispute. What is in dispute is whether knowing him lets you read a toxicology report and overturn it. It does not."
"It lets me see that something is wrong."
"Something," Park agreed. "Something is always wrong when someone dies aboard a vessel. Something is wrong even when the death is entirely natural. We are far from home. We are far from any other body. Every death is a kind of failure of the system, and every death produces a kind of grief that wants, very badly, to find a culprit other than the one the chart describes. I understand that impulse. I am not dismissing it. I am telling you, as gently as I can, that wanting a culprit is not the same as finding one."
Juno was quiet for a long time. The pipe ticked again. Somewhere deeper in the ship, a ventilator cycled.
"He sent me a message," Juno said.
Park did not move.
"The night of the incident. The night of the transmission event. Forty-one minutes before the burst, he sent me a personal message on the secondary channel. I have it. It is on my personal drive. It is not in any official log because it was not an official transmission. It was a note. It said, If anything happens to me, do not let them tell you it was my idea. "
The medical bay was very quiet.
Park's hands, which had been resting on her knees, came together in her lap. She did not look down at them. She kept her eyes on Juno's face.
"I have not included that in my report," Park said, "because it is not a medical finding. It is a personal statement. It could be the ravings of a man who had already decided to end his life and wanted to make it harder for the people who loved him. It could be the message of a man who genuinely feared something. I cannot tell you which."
"You think he was depressed."
"I think," Park said carefully, "that the captain of a vessel that has just lost most of its senior crew in a catastrophic transmission event has the right to be depressed. I think he had the right to be exhausted. I think he had the right to make a choice that I would grieve and that I would document honestly. I do not think the existence of a private note changes the toxicology."
Juno looked at the tablet face-down on the mattress. The screen had gone fully dark now. The report was still there. The verdict was still there. She thought about the captain's hands. She thought about the way he had once corrected her pronunciation of a sector code, gently, on the bridge, in front of three other officers, without ever making her feel small.
"Doctor Park."
"Yes."
"Will you sign a second report."
"No," Park said. "I will not. Not yet. Not until you bring me something I can sign. A witness. A recording. A timestamped anomaly. A pharmacy discrepancy. Something. Until then, the report stands as written, and you are welcome to grieve the captain, and you are welcome to be angry, and you are welcome to stay in this bay until the chamomile goes cold, which it has."
Juno picked up the cup. She drank the rest of it in one go. It was lukewarm and faintly bitter at the end.
She stood. The blanket fell from her shoulders onto the cot. She picked it up, folded it once, set it at the foot of the cot.
"Thank you for the chamomile," she said.
"It was nothing," Park said, and they both knew that was a lie.
Juno walked to the door. She stopped with her hand on the frame.
"Doctor."
"Yes."
"If I bring you something. Something real. You will look at it."
"I will look at it," Park said. "I cannot promise what I will find. But I will look."
Juno nodded once. She stepped into the corridor. The door hissed shut behind her, and the medical bay went quiet again, and the tablet on the cot kept the captain's name in its memory, and the chamomile ring dried on the steel ledge like the small print of a verdict no one had agreed to accept.
The yeoman's voice was still in her ears when Juno turned around.
It had been a short walk from the yeoman's berth to the medical bay. It was a shorter walk back. The corridor was the same corridor. The overhead lights were the same pale yellow that never quite matched the ship's day cycle. The air smelled the same: recycled, faintly metallic, the ghost of the galley two decks up drifting down through the ventilation.
She had gone to the yeoman first. She had needed a witness to the small things, the things doctors did not see. The yeoman had looked her in the eye and had not looked away.
There was a bottle, the yeoman had said. On her nightstand. Brown glass. No label. The cap was off. I noticed it because it was the only thing on the nightstand that did not belong there.
Juno had asked: Are you certain.
The yeoman had said: I am certain.
The yeoman had said: It was not there in the morning.
Juno pressed the door chime.
The door hissed open. Park was standing exactly where Juno had left her, by the counter, by the sink, holding the same cup in the same hand. The only difference was the tablet: it had been picked up from the cot and set face-down on the steel counter, screen against the metal, as if Park could not bear to look at it any longer but could not quite put it away.
"You came back," Park said.
"I did."
"I made more chamomile. It is on the warmer. If you want it."
"I do not want chamomile. I want to ask you three things."
Park set her cup down. She folded her hands in front of her. "Ask."
"The exit vial."
Park's expression did not change. "What about the exit vial."
"The captain did not have one in her quarters. The inventory list from the morning shows no exit vial in the captain's quarters. I would like to know why the captain did not have an exit vial in her quarters."
"I issued her one at the beginning of the voyage. Standard protocol for senior officers on long deployments. She returned it to me. Two months in. She said she did not need it. She returned it with the seal unbroken."
"You are certain the seal was unbroken."
"I am certain. I logged it. I resealed the cabinet. I have the log."
"I would like to see the log."
"You will see it. I will pull it for you in the morning. What is the second thing."
"The concentration."
Park was quiet for a moment. The ship's hum filled the pause, low and constant, the sound of the vessel moving through the dark the way a heart moves blood through a body.
"The sedative," Park said. "In the captain's bloodstream. You want to talk about the level."
"I want to talk about the level."
"The level was consistent with chronic therapeutic use. I wrote that. I would write it again. I have the chromatograph."
"I read the chromatograph," Juno said. "I am not a doctor. I am a communications officer. I have read enough medical reports in three years to know that a level consistent with chronic therapeutic use is also consistent with a single large dose taken within the hour before death. I would like you to tell me which one it was."
Park looked at her. The look was long, and steady, and careful.
"I cannot tell you which one it was," Park said. "My instrument cannot distinguish between them. The reference ranges overlap. The metabolite ratio is the only reliable marker, and my instrument does not measure metabolite ratios. It measures concentration. The concentration was within the therapeutic reference range."
"So you cannot rule out a single large dose."
"I cannot rule it out. I also cannot rule in chronic use. I can only report what the chromatograph showed."
"Could the flag vessel's laboratory distinguish."
"Yes."
"Have you sent them the sample."
"No."
"Why not."
"Because no one has asked me to. Because the cause of death is not in dispute. The cause of death was sedative intoxication. The manner of death is a separate determination, and it is not within my authority to make."
Juno let that sit. She let the ship's hum fill the silence. She let Park see that she was not satisfied.
"What is the third thing," Park said.
"The bottle."
Park's hand moved, just slightly, toward the cup she had set down. She did not pick it up. She let her hand rest on the steel counter beside it.
"There was a bottle," Juno said. "On the captain's nightstand. The night she died. Brown glass. No label. The cap was off."
"I was not in the captain's quarters that night."
"I know you were not. The yeoman was. The yeoman saw it."
"The yeoman is not a medical officer."
"The yeoman is a witness. The yeoman saw the bottle. The yeoman did not see it the next morning. The nightstand was empty except for the lamp, the tablet, and the captain's pin. The bottle was gone."
Park did not answer immediately. She looked at the cup. She looked at the tablet, face-down on the counter. She looked at the steel ledge where the chamomile ring was drying.
"I inventoried the body," Park said. "I drew the blood. I ran the chromatograph. I filed the report. I did not inventory the nightstand."
"You did not see the bottle."
"I did not see the bottle."
"You did not see it the next morning, either."
"I did not see anything the next morning except the captain."
"Security saw the nightstand. Security inventoried the room. Security would have noted a bottle."
"Yes."
"Security did not note a bottle."
"I would not know. I was not present for the security sweep. I was not shown the security inventory."
"Doctor. I am telling you that there was a bottle. I am telling you that the bottle is gone. I am telling you that I would like to know where the bottle is."
"I cannot tell you where the bottle is," Park said. "I can only tell you what I have. I have the chromatograph. I have the body. I have the report. I do not have the bottle."
"If I find the bottle."
"There is no bottle."
"If I find the bottle and bring it to you. Will you analyze it."
Park was quiet for a long time. The ship's hum filled the silence. The chamomile on the warmer sent up a thin curl of steam that caught the overhead light and disappeared.
"I will analyze whatever you bring me," Park said. "I cannot promise what the analysis will show. I cannot promise that it will show anything at all. But I will analyze it."
"Thank you."
"Do not thank me yet."
Juno nodded. She looked at Park for a moment, at the cup she had not drunk, at the tablet face-down on the counter, at the careful hands folded in front of her.
"One more thing," Juno said.
"Yes."
"The exit vial. The one the captain returned. The one in your locked cabinet."
"Yes."
"Has anyone accessed that cabinet since the captain returned it. To your knowledge."
Park did not move. Her hands stayed folded. Her eyes stayed on Juno's.
"I have accessed it," Park said.
"When."
"This morning. To confirm the log. To verify the seal."
"And before this morning."
Park was quiet. The ship's hum filled the silence.
"Not to my knowledge," Park said.
"Doctor."
"Yes."
"I am asking you specifically. Has anyone accessed that cabinet, by your knowledge, between the time the captain returned it and this morning."
Park's hand moved, just slightly, toward the cup. She stopped herself. She folded her hand back into the other one.
"I am not aware of anyone accessing that cabinet," Park said. "I cannot speak to what I am not aware of."
"Thank you," Juno said.
She turned toward the door. She stopped with her hand on the frame.
"Doctor."
"Yes."
"If the seal on the cabinet was broken this morning. Would you have known."
Park did not answer immediately. The ship's hum filled the silence. The chamomile ring on the steel ledge caught the overhead light.
"I would have known," Park said.
"Thank you," Juno said.
She stepped into the corridor. The door hissed shut behind her. The medical bay went quiet again. Park stood by the counter and looked at the cup she had not drunk from and did not move for a long time.
The corridor stretched long and cold, the emergency strip lighting casting everything in a thin amber wash. Juno's boots made no sound on the deck plating. She had taken them off without thinking, the soft soles of her station socks pressing flat against the metal, and she stood now in the dim half-light between Bays 4 and 5 with her shoes dangling from two fingers and the ghost of Doctor Park's chamomile still clinging to her sinuses.
She let herself breathe.
Then she turned and padded toward the captain's quarters.
The door was sealed. Of course it was sealed. A yellow strip of crime scene tape crossed the frame at chest height, the kind they used aboard the vessel for any incident under formal review. The tape bore a date and an authorization code in stamped black ink. Juno did not touch it. She stood at the threshold and studied the deadbolt housing the way she had once studied signal arrays during her first watch rotation, with the patient hunger of someone trying to read a language she had only begun to learn.
The deadbolt was a standard Fleet model. The throw was a quarter inch of hardened steel. The housing was brushed alloy. It threw to the right when locked. It threw to the left when unlocked. The throw, in this case, had been forced.
She saw it in the faint scoring on the alloy face. Two hairline crescents, parallel, at the height of the bolt's travel. They caught the amber light at a different angle from the brushed finish around them. Someone had slid a thin instrument into the gap between the door and the jamb and pried the bolt back. They had done it from the outside. The crescents curved away from the door. They curved toward the corridor.
Someone who knew the lock's tolerances. Someone who had practiced.
She let that settle in her chest.
The override code was four digits long and rotated every seventy-two hours. Only the captain and the executive officer held override authority in case of catastrophic failure. The captain was dead. The executive officer was dead. Juno had the secondary override, which every junior officer carried for emergencies, but the secondary did not bypass a forced bolt. It simply unlocked the door once the bolt was retracted. It assumed the bolt would be where it was supposed to be.
She keyed her secondary into the wall panel.
The door hissed open.
The captain's quarters smelled of paper and soap and something faintly resinous, like pine sap, though there were no pine trees within a hundred light-years. The air had been recycled so many times it had lost its mineral bite and taken on the flat, sweet undertone of the ship's filtration system. Juno stood on the threshold and let the room breathe against her face.
It was a small space. Two bunks, the upper one folded flat against the bulkhead, the lower one made down. A desk with a fixed chair. A sealed viewport, the polarizer on, showing only a dim grey wash. A narrow closet with the captain's dress uniform hanging in its bag. A single mug on the desk.
Juno stepped inside. She did not close the door behind her. The corridor light fell across the floor in a long, thin rectangle.
The mug first.
She circled the desk without touching it. The mug sat on a square of paper towel that had not been there before. She did not need to ask how she knew this. She had helped the captain unpack during the third week of the cruise. She had watched the captain set her mug, her own mug, brought from home, on the bare corner of the desk nearest the chair and adjust it three times until the handle pointed to the wall.
The paper towel had been laid by someone with steady hands. It was centered. The mug was centered on it. There was no ring. The surface of the paper towel was dry and pale, unmarked, and Juno understood, with the slow click of a tumbler falling into place, that someone had anticipated a ring and prepared for it. Someone had placed the mug down with extraordinary care, lifted it, examined the surface beneath it, found nothing, and replaced it on a fresh square.
No one drinks from a mug that carefully.
She crouched. The underside of the desk showed a faint shadow where a previous mug had sat, the ghost of a ring etched into the finish over years of use. The captain's ring. The mug on the paper towel was the same model. Same color. Same handle orientation. The replacement was precise.
She straightened.
The bunk.
Juno crossed the small space and stood over the lower berth. The bedding was regulation cotton, ship-issue, grey. The captain had made her own bunk every morning of the cruise, a fact Juno knew because she had stood watch at the door of these quarters more times than she could count and had watched, through the crack of the hinge, the captain's hands smoothing the sheet, tucking the corner, folding the blanket into a tight hospital square.
The bunk in front of her was made, but it was wrong.
The sheet was tucked at the foot. The sheet was not tucked at the head. The blanket was folded into a square, but the square was oriented with its open end toward the bulkhead, not toward the door, which was the convention aboard a Fleet vessel where every bunk could be inspected from the corridor by a passing officer. The pillow had been fluffed. No one aboard this ship fluffed a pillow. The pillowcase had a crease across its center that ran longwise, the way a pillow was folded for storage in a kit, not the way it was arranged on an active berth.
Someone had re-made this bunk who had never made a bunk aboard a Navy vessel.
Someone who had seen the procedure. Someone who had perhaps watched tutorials, or read a manual, or studied photographs. Someone who had the discipline to make the attempt and not the training to make it correctly.
Juno stood very still.
The captain had not made this bunk. The captain had not drunk from that mug. The captain had not closed that bolt from the inside. The captain had not, in any meaningful sense, occupied this room in the way the crime scene report assumed she had.
Juno looked at the mug. She looked at the bunk. She looked at the door.
She thought of Park's hands folded in front of her. She thought of Park's hand moving toward the cup and stopping. She thought of the chamomile ring on the steel ledge and the lock that only two people could open.
She thought of the override code that had not been used.
She sat down on the deck plating, cross-legged, her shoes still dangling from one hand, and let the captain's quarters hold her while the pieces arranged themselves into a shape she did not yet want to name.
The mug waited. The bunk waited. The deadbolt housing held its thin crescents like a pair of old scars.
Somewhere below her, in the medical bay, Doctor Park was still standing by her counter, looking at a cup she had not drunk from, listening to the ship breathe the way a guilty woman listens to a house settle after she has told a careful, technical lie.
Juno closed her eyes.
The chapter turned over like a leaf.
